Succubus on Top CHAPTER 18

â€Å"That's not funny,† I said. â€Å"Seems like a sensible question.† I took a gander at him and afterward folded my arms over myself. â€Å"Is that all you're going to say?† â€Å"I†¦I don't generally have the foggiest idea what else to say.† â€Å"This is where you holler at me.† His eyebrows rose. â€Å"Oh, I see. I didn't have the foggiest idea about this was at that point scripted out. â€Å" â€Å"That's not what†¦look. I laid down with another person. Furthermore, not simply rested. I didn't need to do it†¦not the manner in which I need to with people. You get that, right?† â€Å"Yes,† he stated, still dead quiet. â€Å"And I wasn't smashed or anything. Woozy possibly, yet at the same time in charge of my senses.† â€Å"Yes.† â€Å"So aren't you mad?† â€Å"Stunned is the prevailing feeling right now. Discovering somebody mimicked you is practically more alarming than the sex part.† â€Å"He didn't imitate you, perse†¦I mean, I realized it was him.† â€Å"I know. In any case, it's still weird.† At the point when he fell quiet once more, I could just gaze with doubt. He got my look and retuned it. â€Å"What do you want?† This time he sounded irritated, practically irate. â€Å"Do you need me to be distraught? Will that like†¦punish you or something? Is that what you want?† I didn't utter a word and understood that was actually what I needed. I had perused a book once where a person unintentionally murdered a young lady while driving alcoholic. His amazing family had figured out how to keep him out of prison, and he'd abhorred it. He'd needed the purifying cleansing of genuine discipline, of paying for his violations. At the present time, I required something very similar. â€Å"I merit it,† I told Seth. His voice was cold. â€Å"Well, I'm not going to offer it to you at the present time. You can't direct what I feel. Sorry.† My mouth began to drop open, uncertain how to manage this unforeseen development. The ringing of my phone intruded on my rumination. I looked at my handbag, at that point let the telephone go to phone message. After a second, it rang once more. â€Å"You should answer it,† Seth let me know. I would not like to converse with anybody. I needed to creep into an opening. Be that as it may, I got the telephone and read the presentation. Nobody I perceived. At times that was Jerome. On the off chance that I didn't reply, the evil presence was probably going to transport on finished, and that was conceivably the main thing that could exacerbate this situation. â€Å"I'm sorry,† I said delicately to Seth, not long before I replied. I didn't have the foggiest idea whether I was saying 'sorry' for the interference or what I'd finished with Bastien. â€Å"Hello?† â€Å"Hey, Georgina. This is Wyatt.† It took me a second. From Doug's band. â€Å"Hey, how's it going?† â€Å"Bad. I didn't have the foggiest idea who else to call. I'm at the medical clinic with Doug. â€Å" My heart halted. â€Å"Oh my God. What happened?† â€Å"He, uh, took some pills.† â€Å"What sort of pills?† â€Å"Not sure. Be that as it may, he took an entire jug of them.† Wyatt's news prodded Seth and me to activity. It was interesting how catastrophe could abrogate outrage. Whatever uncertain issues caught us, we put them on pause as I drove us downtown. Wyatt had quickly recounted to the remainder of the story as I'd left my loft at a run. Alec hadn't come through with his most recent shipment. Doug had slammed once more, diving into that terrifying dimness I'd saw previously. Wyatt didn't totally have the foggiest idea what had set off the overdose. He accused everything from a self-destructive inclination to a urgent endeavor at recovering the high through different methods. The crisis room had siphoned his stomach, and the specialist said he was alright until further notice, however he hadn't yet recaptured awareness. Wyatt had called me in light of the fact that Doug had no family here, and nobody realized how to contact the ones who lived away. Corey and Min were there when we showed up. They explained more for us and said there was no adjustment in Doug's condition. Seth remained quiet, yet I could tell he was as worried as I might have been. I inquired as to whether I could see Doug, and a medical attendant disclosed to me I could. I went into the room alone and discovered him snoozing, snared to tubes and a bleeping machine. I had watched clinical innovation change throughout the years, from bloodsuckers to defibrillators, yet that didn't mean I felt OK with any of it. Machines that kept individuals alive annoyed me. They weren't regular, regardless of whether they did great. â€Å"Oh, Doug,† I mumbled, sitting at his bedside. His skin was pale, his hand cold and sticky. The bleeping machine enlisted a consistent heartbeat, so that was something. None of different readouts implied anything to me. I watched him, feeling vulnerable. Humans, I thought, were delicate things, and there was no way around that. Many, numerous years prior, Bastien and I had worked at a ballroom in Paris. Artists in those days were quite often whores as well, yet I hadn't disapproved. The open door had furnished me with both succubus vitality and money related salary. Bastien had been a bouncer and apparently my sweetheart. This permitted him to praise me excitedly, reinforcing my notoriety and sending me a huge customer base. â€Å"There's a youngster who appears each night,† the incubus revealed to me one day. â€Å"He has ‘virgin' stepped all over him, yet he's rich as well. I've conversed with him a couple of times. He doesn't care for paying for sex, yet he's totally fixated on you.† The news satisfied me, and when Bastien brought up the respectable man, I reached him all through the exhibition. Sufficiently sure, a steward of his discretely requested me in the interest of his manager a short time later, and I rushed to set myself up behind the stage. â€Å"Josephine,† called a voice adjacent to me. I turned and saw another artist, a particular companion of mine named Dominique. â€Å"Hey,† I advised her, smiling. â€Å"I have a decent possibility I must get to.† Her troubling face made me delay. â€Å"What's wrong?† Dominique was little and fair, with a nearly waifish appearance that made her seem as though she wasn't getting enough to eat. That wasn't an astonishment, in any case. None of us in that calling at any point got enough to eat. â€Å"Josephine†¦Ã¢â‚¬  she mumbled, blue eyes wide. â€Å"I need your assistance. I think†¦I believe I'm pregnant.† I halted abruptly. â€Å"Are you sure?† â€Å"Pretty sure. I†¦I don't have a clue what to do. I need this activity. You know I do.† I gestured. From the wings, Jean †the man who took cuts from our contacts †hollered at me to hustle just a bit and meet my youngster. I gave Dominique a brisk embrace. â€Å"I need to go do this. I'll see you later, alright? We'll figure something out.† Be that as it may, I never truly got a later. The youngster, Etienne, end up being lovable. He was a lot more youthful than my evident age, and connected with to be hitched. He was torn on the issue of sex. Some portion of him felt he should have been unadulterated for his lady of the hour; the other part needed to be experienced on his wedding night. That was the part that won out, the part that carried him to my bed and gave me the succubus reward of both an ethical debasement and a vitality yield. He hated me for both my way of life and my hold over him, however that didn't prevent him from returning each day for the following hardly any weeks. â€Å"I detest you for this,† he disclosed to me one day after we'd been together. He lay back against the sheets, in a sweat-soaked, postcoital rest. I remained close to the bed, getting into my garments while he viewed. â€Å"Marry me.† I roared with laughter, hurling my hair †at that point nectar light and wavy †more than one shoulder. He flushed irately. He had dim eyes and hair and a perpetually agonizing look. â€Å"Is that funny?† â€Å"Only in light of the fact that you despise me in one breath and love me in the other.† I grinned as I bound up my underpants. â€Å"I assume there are a great deal of relationships like that.† â€Å"Not everything's a joke,† he said. â€Å"Maybe not,† I concurred. â€Å"But this comes pretty close.† â€Å"Are you turning me down?† I pulled my dress over my head. â€Å"Of course I am. You have no clue about what you're inquiring. It's ridiculous.† â€Å"You treat me like I'm a kid sometimes,† he proclaimed, sitting up fix â€Å"You're not that a lot more seasoned than me. You reserve no privilege to act so wise†¦especially since you're a†¦Ã¢â‚¬  I smiled at him. â€Å"A whore?† He had the elegance to look humiliated. â€Å"And that, sweeting, is the issue. Quit worrying about your family's scandalized response. Regardless of whether we figured out how to pull it off, you'd never get over that. You'd spend the remainder of our marriage †which would likely be fleeting †fixating on all the men I'd been with. Thinking about whether one of them had been something more. Thinking about whether I'd accomplished something with them that you thought was new and novel with you.† Irate, he stood up and pulled on his jeans. â€Å"I would have thought you'd be grateful.† â€Å"Flattered,† I said icily, â€Å"but nothing more.† That wasn't altogether evident. The reality of the situation was, in spite of his energetic conviction and emotional episodes, I loved Etienne. A ton. Something about him spoke to me. Perhaps it was on the grounds that all that emotionality and pride originated from a masterful nature. He painted as a leisure activity. There it was once more, my heartbreaking fixation on imaginative men. Fortunately, around then in my life, I had enough sense to stay away from profound entrapments with people. â€Å"I wish you could pick who you love,† he said sharply. â€Å"Because I wouldn't pick you, you know. Be that as it may, here we are. I can't quit pondering you. I feel like there's some draw to you I can't fight.† â€Å"I'm sorry,† I said delicately, astonished at the little throb in my heart. â€Å"Wait until you're hitched. Your significant other will cause you to overlook me.† â€Å"No. She doesn't even compare.† â€Å"Plain?† Egotistical of me, maybe, yet I heard it a great deal. â€Å"B

You know what would be cool

“You know what would be cool” That phrase is probably the most uttered string of words I hear. Its 0400 Saturday morning, and my roommate and I sit listening to whatever Pandora has queued up for us, sipping homemade sweet tea and tossing ideas around like basketballs of our more athletically inclined friends. Weve spent hours at a time like this, discussing topics ranging from Computer Science to Student Life, the best way to get free food and every tangent in between. Its in these aloof conversations that I really appreciate one of the more unsung parts of MIT: People here are very clever. You see, lets be honest here for a second. There are plenty of very respectable universities that you can go to for your education. Its not like MIT teaches some secret form of Math that no one else knows about. Heck you can even kill yourself with homework if you really want to try and emulate what its like to be here (as a sidenote, I recently learned that going for 35 hours without sleeping makes your thoughts indistinguishable from someone with a severe mental disorder in an MRI. This makes me want to wear a tactical vest and be very nice to everyone on campus). But what really sets MIT apart from other institutions is the incredibly stimulating thinktank nature of people around here. Thinking is a hobby for many people around here, and for the hard stuff, theyre really good at it. The more trivial things, like Does orange plaid match with a floral green print? or Should I wash my hair this week? seem to stump some people, but given that they could make a supercomputer using nothing but soda cans, hairspray, 3 rubber bands, and Karmic Koala; its definitely forgivable. You neednt click further than the Notable Alumni page to see a good number of people whos accomplishments Id venture to say started off as the sort of humble ideas that populate the dialogue of students around here. But it doesnt even have to be serious stuff. People here drop pumpkins off buildings for fun, and turn grocery carts into high speed go-karts for no other reason than because they can. Its a sort of art really, engineering as expression. Its no surprise then to see this creativity transfer to problem solving, seeing people win grants and contests is a such a regular occurence that its not until Im away from campus that it really sinks in how cool that is. Thats nothing short of exhilarating to me, to know that the people eating lunch at Subway next to me are future Nobel Laureates (scientific ones nonetheless. You know, the ones that are hard to get), engineers of advances in space travel, and doctors who will cure cancer. The guy getting his bagel from LaVerdes could be a MacArthur fellow, whose annoyance with the local price discrepancy (read: gouging) spurs him to invent a bagel tree that solves world hunger. Who knows what paradigm shifting idea is starting right now in someones room or the coffee table in lobby 7. This is a place of dreamers, thinkers, and creators. The impossibles dying breath is you know what would be cool? because with it comes the beginning of ingenuity so profound that it makes the all the hours spent reading, tooling, and being awake well worth it.

For this assessment all names have been removed or altered to protect the individuals involved which is in accordance with the Privacy Act 1993 (Parliamentary Counsel Office [PCO], 2009).

Also this will be established once the breach report has been completed and if investigations result in a breach of opinion. According to the HDC (2008) the Health Practitioners Competence Assurance Act 2003 has accepted the naming of health practitioners at the discretion of the Commissioner as the decision to name is not within the scope of the HPDT name suppression order.

Marco Polo Essays - Marco Polo, Eurasia, Asia,

Marco Polo Marco Polo is one of the most well-known heroic travelers and traders around the world. In my paper I will discuss with you Marco Polo's life, his travels, and his visit to China to see the great Khan. Marco Polo was born in c.1254 in Venice. He was a Venetian explorer and merchant whose account of his travels in Asia was the primary source for the European image of the Far East until the late 19th century. Marco's father, Niccol?, and his uncle Maffeo had traveled to China (1260-69) as merchants. When they left (1271) Venice to return to China, they were accompanied by 17-year-old Marco and two priests. Early Life Despite his enduring fame, very little was known about the personal life of Marco Polo. It is known that he was born into a leading Venetian family of merchants. He also lived during a propitious time in world history, when the height of Venice's influence as a city-state coincided with the greatest extent of Mongol conquest of Asia(Li Man Kin 9). Ruled by Kublai Khan, the Mongol Empire stretched all the way from China to Russia and the Levant. The Mongol hordes also threatened other parts of Europe, particularly Poland and Hungary, inspiring fear everywhere by their bloodthirsty advances. Yet the ruthless methods brought a measure of stability to the lands they controlled, opening up trade routes such as the famous Silk Road. Eventually ,the Mongols discovered that it was more profitable to collect tribute from people than to kill them outright, and this policy too stimulated trade(Hull 23). Into this favorable atmosphere a number of European traders ventured, including the family of Marco Polo. The Polos had long-established ties in the Levant and around the Black Sea: for example, they owned property in Constantinople, and Marco's uncle, for whom he was named, had a home in Sudak in the Crimea(Rugoff 8). From Sudak, around 1260, another uncle, Maffeo, and Marco's father, Niccol?, made a trading visit into Mongol territory, the land of the Golden Horde(Russia), ruled by Berke Khan. While they were there, a war broke out between Berke and the Cowan of Levant , blocking their return home. Thus Niccol? and Maffeo traveled deeper into mongol territory, moving southeast to Bukhara, which was ruled by a third Cowan. While waiting there, they met an emissary traveling farther eastward who invited them to accompany him to the court of the great Cowan, Kublai, in Cathay(modern China). In Cathay, Kublai Khan gave the Polos a friendly reception, appointed them his emissaries to th e pope, and ensured their safe travel back to Europe(Steffof 10). They were to return to Cathay with one hundred learned men who could instruct the Mongols in the Christian religion and the liberal arts. In 1269, Niccol? and Maffeo Polo arrived back in Venice, where Niccol? found out his wife had died while he was gone(Rugoff 5). Their son, Marco, who was only about fifteen years old, had been only six or younger when his father left home:thus; Marco was reared primarily by his mother and the extended Polo family-and the streets of Venice. After his mother's death, Marco had probably begun to think of himself as something of a orphan(Rugoff 6). Then his father and uncle suddenly reappeared, as if from the dead, after nine years of traveling in far-off, romantic lands. These experiences were the formative influences on young Marco, and one can see their effects mirrored in his character: a combination of sensitivity and toughness, independence and loyalty, motivated by an eagerness for adventure, a love of stories, and a desire to please or impress(Li Man Kin 10). Life's Work In 1268, Pope Clement IV died, and a two- or three-year delay while another pope was being elected gave young Marco time to mature and to absorb the tales of his father and uncle. Marco was seventeen years old when he, his father and uncle finally set out for the court of Kublai Khan(Stefoff 13). They were accompanied not by one hundred wise men but by two Dominican friars, and the two good friars turned back at the first sign of adversity, another local war in the Levant. Aside from the pope's messages, the only spiritual gift Europe was able

Essay Sample on Mathematics The System of Linear Equations

Essay Sample on Mathematics The System of Linear Equations PATTERNS WITHIN SYSTEM OF LINEAR EQUATION A system of linear equation is basically dealt with in the algebra unit. It is a collection of the linear equations involving variables of the same set in the in the equations that are involved. For example a 2Ãâ€"2 system of linear equations includes: x + 2y=10 3x + 4y=15 Here in both the cases the equations only involve two variables that is x and y and no other variable is included. In the example of a 33 system of linear equations it mostly includes the variables x, y and z for example; 2x + y-z =11 x- 2y + 2z =-2 3x-y+2z =5 Where only the three variables are involved There are also various properties of the patterns of the linear systems. We will start with the consistency property. If the systems of the equations have common solutions, then they are said to be consistent. This therefore means that graphically the lines should be straight lines. The independence property is also termed as the linear independence. The systems of equations are usually independent since to start with, they are derived algebraically from others. For example the system 3x+4y =9 and 6x +8y =18. There are different ways of solving the systems of linear equations that includes; The elimination of variables The substitution of variables technique The row reduction method The crammers’ rule The matrix method In the mathematical field, the general linear equation in the x and y is Ax+By=C where both the A and B in the equation are not zeros. The y-intercept in the line is the y-coordinate of that point where graphically, the non-vertical line that is drawn either manually or graphically intersects the y-axis. Also, the x-intercept is the point where the non horizontal line crosses the x-axis. Therefore the most general equation for a line with slope m and the y-intercept passing through b as the y intercept is written as y= mx + b. Therefore, one can easily find the slope and at the same time the y-intercept of any line. For example finding the slope and the y-intercept for 4x+5y=40 Solution: first and foremost, solve the equation for y to put it in the slope intercept format 4x+5y=20 5y=20-4x y=4-4/5x y=-4/5x+4 therefore the slope m=-4/5 and the y intercept is b=4 Consider this 2Ãâ€"2 system of linear equations 4x+3y=7 3x-2y=9 When we examine our first equation 4x+3y=7, there is a pattern in the constants of the equations used. Here 4 is the constant associated with the variable x and it therefore precedes the variable x. Also 3 is a constant that is preceding the variable y and the equation results to 7. In the second equation, 3x-2y=9, the constant 3 precedes our variable x and the constant -2 precedes the variable y making the equation to result to 9. It is also clear that in the two equations, the constants both have a difference of one. Solving the equations simultaneously, we first multiply the first equation by 3 and then multiply the second equation by 4 in order to eliminate the variable x and solve for the variable y. The equation then becomes; 12x+9y=21 12x-8y=36 17y=-15 Therefore solving the equation yields y=-15/17. Putting the value of x in any of the solution to obtain the value of x; 4(x) +3(-15/17) = 21 X=41/17 Graphically the system of equation is solved as This is first done by putting the two equations in the form of y=mx+b. The solution of the equations is by observing the point of intersection of the two lines that are plotted graphically. In this system of equation the solution therefore is (41/17, -15/17) Consider this 2Ãâ€"2 system of linear equations x+2y=3 and 2x-y=-4 The two equations are linear because the unknowns only appear to the first power, no unknown in the denominator of a fraction is in the equations and there are no products of unknowns. Therefore, the most general linear equation is a11x1 + a12x2 ++ a1nxn=b1 a21x1 +a22x2++a2nxn=b2 am1x1+ am2x1 +..+amnxn=bm m With unknowns x1, x2..xn and coefficients a1, a2an . In x+2y=3, the constant is 3 and the unknowns are x and y whereby x= 3-2y and y= (3-x) à ·2. The gradient of the linear equation is -1/2 and the y- intercept is 3/2. The gradient is negative therefore it is negatively sloped. In 2x-y =-4, the constant is -4 and the unknowns are x and y where x= (y-4) à ·2 and y=2x+4. The gradient of the line is 2 and the y- intercept is 4. The gradient is positive and therefore positively sloped. Each of the unknown variables can be solved using the graphical calculator in the matrix calculation area [1 2: 3] and [2 -1: -4] The inverse is The solution therefore is; 1 2: x =3 2 -1: y =-4 1/5 2/5 3 =x 2/5 -1/5 -4 =y The graphic calculator here was used during this step to solve the matrix equation, normally if the equation is Ax= B then the solution is x= A-1B X=-1 y=2 The first function from the graph is sloped from left to right that is it is negatively sloped since the gradient is negative and the second equation is sloped from right to left since the gradient is positive. From the graph the solution of the equations is x and y2. This is read directly from the graph where the two lines intersect. In short, the solution to the system of equation is unique in that there is only one solution set to the system of equations and the solution satisfies the individual equations in the system of equations. Therefore, when x=-1 and y=2. Then -1+ (2Ãâ€"2) =3 and (2Ãâ€"-1) 2 = -4 which satisfy the equations that are given. Another example of linear equations is x+2y =3 3x-5y=9 This is a system of equations since it contains more than one equation. The solution set to the system of linear equation is the set of numbers n and m such that if we let x=n and y=m then we will obtain the result of the right hand side of the equation. For instance ax+by =c, if x=n and y=m then we obtain the result c given a and b are known constants. Each of the unknown variables can be solved using the graphical calculator in the matrix calculation area 1 2: x =3 3 -5: y =9 The inverse of the equation is -5/11 -2/11 -3/11 1/11 The solution therefore is, -5/11 -2/11 3 =x -3/11 1/11 9 =y Therefore xand y The graph of the two equations is as shown below This is so since (3 1) + (2 0) =3 and (33)-(50) = 9 as proven from the equation. Now consider the 2 2 system below x2y=4 5x-y=1/5 In the first equation, x2y=4 f(x) = x/8. Therefore (0, 0) In the second equation, 5x-y=1/5 then f(x) = 5x-1/5. The gradient is 5 and the y intercept is -1/5 The matrix of the equation therefore is [1/8 -1: 0] [5 -1: 1/5] Each of the unknown variables can be solved using the graphical calculator in the matrix calculation area -39/8 39/8: 0 = x -195/8 39/64: 1/5 = y Consider the following two by two system of equation y + 2x=7 y + x/2=3 In the first equation, the line is negatively sloped since y= f(x) = -2x+7. The gradient is -2 which means that the change in x compared to the change in y is -2. The y intercept is 7 and therefore when x=0, y=7 In the second equation, the equation line is also negatively sloped. The equation y= f(x) =-x/2 +3. The gradient is -1/2 and the y- intercept is 3 meaning when x=0, y=3 Each of the unknown variables can be solved using the graphical calculator in the matrix calculation area Therefore the solution to the equation is x=8/3 and y=5/3 The graph of f(x) =-2x+7 and f(x) =-x/2+3 are as follows: From the graph both the linear equations are negatively sloping but that of f(x)= -2x+1 is steeper than that of –x/2 + 3. The equations above are linear equations that results to linear curves and therefore two equations are enough to solve the equations. This two equations result into a square matrix. In the multiplication of matrices for instances, if A is an np matrix and B is a pm, then AB is the product of A and B denoted by AB and AB will be an nm matrix. That is AB exists if and only if number of columns of A is equal to the number of rows of B and that it should be noted that ABBA therefore the matrices do not commute. Therefore in solving the equation for example Ax=B, to find the values of x, the inverse of A is first found then multiplied by B. That is x= A-1B If A is a square matrix, we can find another matrix B known as the inverse of the matrix such that AB=BA=I. The inverse however can be a right inverse or a left inverse most commonly denoted as A-1. If AB=BA=I then A-1= B. Therefore if B exists then A is said to be invertible and non singular matrix. If B does not exist then A is said to be singular matrix. For the solution to be found in the equations, the matrix involved should be non singular. Theorem If A is a non singular matrix then A-1 is unique Proof Let A-1 =B then AB=BA=I Suppose B is not unique, then there exist C such that CB Then CA=AC=I But B=IB therefore (AC) B= (CA) B and thus C (AB) =CI =C Therefore B=C, a contradiction that B is unique An example of invertible matrix can be solved by looking at the following question. Solve the equations -4x-2y=8 and 6x+3y=12 The matrix of the equation is a 22 matrix and therefore the equation can written in the augmented form as shown Any matrix is said to be in reduced row echelon form if it satisfies the following conditions: Any row of all zeros appear at the bottom If a row does not consist of all zeros then its first non zero entity is called a leading 1 and it is one If any two successive rows the leading 1 of the lower is further to the right of the leading 1 of the highest row If a column contains a leading 1 then all the other entries are zero However, each of the unknown variables can be solved using the graphical calculator in the matrix calculation area But the inverse of the matrix does not exist since in fact the determinant is zero (-43) (6-2) =0. Therefore there is no solution to the equation above. Graphically, the lines to the equations are parallel and never intersect therefore there is no solution to the problems From the graph, it is clear that the two lines are parallel and are never to intersect and therefore this means that the equations do not have a solution. In some cases, the system will have many solutions in the algebraic sense, however geometrically, the lines will collide and look like there is only one line and therefore all the points along that line are indeed solutions to the equation. For example the equation -2x+y=8 and -4x+2y= 16 matrix to the equation is One of the solutions is x=0 and y=-4 and many other solutions. The matrix does not have an inverse as shown by the graphical calculator in the matrix calculation area since the determinant of the matrix is zero. This means that the solution of the equation is not one hence the equation has many solutions. In general, given any systems of linear equation with two unknown solution, the two lines will graphically intersect at one point. The point of intersection is the solution to the systems of linear equations. Also, the lines can be parallel to each other meaning that the system does not have any solution and finally the lines can collide and the solution to the system is not unique that is there are many solutions to the system of linear equations. The system with many solutions can be presented in the graph below using the equation given above. Note that: -4x+2y=16 2 {(-2x+y) =8} and therefore one equation is a multiple of the other which basically means that the equation is more or less the same. Remember that a system such as 2x-3y=7 and x+7y=11 can be written in the form = It is normally represented as Am=b where A= , b= and m= If b=0, then the system Am= b has m=0 as a trivial solution but if A-1 exists then m=0 is the only solution to the system. There is also the possibility of graphing those equations with piecewise defined functions. For instance there are functions such as |x| = In our example, we will graph one of the most commonly used piecewise defined functions. f (x) = In this case, the entire function is considered as one function in who’s the domain is the real numbers. APPLICATION OF LINEAR FUNCTIONS There are times when the solutions for the complicated functions cannot easily be obtained. This lead to the use of the linear equations that is the equations that are to only one degree to be used in the approximation of the complicated functions since they gives some little bit of accuracy and the linear functions are easy to work with. This is basically known as linearization. This is mostly used in conjunction with the differential functions. Here if the function, normally denoted as f is differentiable at x=a, then in this case the approximation function denoted as L(x) = f (a) +f’ (a) (x-a) is now what is known as the linearization of the function f at a. For example we will try to find the linearization of the function f(x) = at x=0 The above graph is now the linearization of the function at x=o and x=3. We now know that f’(x) =1/2(1+x)-1/2. We will therefore see that f (0) =1 and also that f’ (0) =1/2. Therefore this concludes that the linearization will therefore be: L(x) = 1+1/2(x-0) = 1+x/2 These are some of the general applications of the linear equations/functions and many other that are dealt with at the higher level of the course work Theorem in the solution of system of equation If A is invertible, then there is only one solution to Am=b which is the unique solution Proof Let w be any solution such that wA-1b That is Aw=b but since A is invertible A-1 exists that is Aw=b Therefore multiplying both sides to the left with A-1 we have A-1Aw = A-1b I w = A-1b w = A-1b which is a contradiction and therefore A-1b is the only solution to the system Next there are equations that are to the second degree and the linear equations are used to find the gradients at particular points through the use of the tangent line and the normal lines to the equations that are being considered in this case. These equations mostly include the parabolas and other quadratic equations among others. Though our main interest is not the parabolas and such equations, the linear equations are particularly used here to serve various mathematical purposes. The parabola for instance is a set that usually consist of all points in a plane that is equal in distance sense from a point that is given and also a given line. Mostly the parabolas will have a graph of equations of the form y= ax2+bx+c. We will for instance plot a graph of y=x2. In this case the graph is a simple graph that is curved in u shape. But mathematically, we may want to find the gradient of the graph at particular points. We will therefore use the current technology for graph plotting to plot both the graphs as shown; The tangent line is used to find the gradient of the curve at that particular point. The graph shown is a curve with the equation y=x2. The axis of the parabola is the y-axis that is it is the axis of symmetry.lso, the vertex of the parabola as seen from the graph is at the origin. The parabola is seen to open upwards when the values of the constant are positive and increasing and open up downwards if the values of the constant are negatively increasing. Now if we consider the 33 matrix system, there are 3 variables that are involved, we will concentrate on the variables x, y and z. For instance, let as consider the matrix below 2x+y-z=11: Here the constants are 2 that precede the variable x, 1 that precedes the variable y and -1 that precedes the variable z. The system can be solved using the usual matrix method, the elimination method or the use of a three dimension matrices. When we deal with the matrix method the graphing calculator here is used to find the inverse of the matrix. The system of equations can be basically being written as; M X=A Using the graphing calculator to find the inverse of the matrix will yield X= M-1A X= And therefore the solution to the equation becomes X = In this type of system, there are also the possibility of obtaining a unique solution, the; possibility of many solution and the option of no solution. The possibility of many solutions or no solution is as a result of having a singular matrix that is a matrix with a zero determinant. For example looking at the following system of solution x+2y+3z=4 4x+6y+8z=10 2x+y=-1 The determinant of the matrix is zero and therefore there can be the case where there are many solutions and graphically in a three dimension graph, the lines are common or the case where there are is no solution and the lines are parallel to each other. We can also use our technology to create a family of linear equations that are usually similar in characteristics. On the same set of the axis, we usually display the equations and evaluate them mathematically. The family of curves will include several lines which usually have a wide range of equations. This can be represented as; The family of linear equations above all have different gradients fro negative to zero to positive. In a 33 matrix, the solution can also be obtained geometrically and algebraically. This is so because the graph of the equations can be plotted in the graph especially with the current technologies and calculators and it can be done algebraically through various methods which include the elimination methods and the current modern methods. Therefore the 33 matrix can be dealt with in the same manner as the 22 matrix. There are many ways of proving mathematical theorems and terms such as the contradiction method, proving by induction and many others in the above matrix we have used the contradiction method. In the 33 matrix, we are going to basically see how to prove by induction the conjectures that are involved. Conjectures in mathematics are some of the propositions and they are easily not disapproved since they are believed to be true For instance the sequence an= n (n-1) is the sequence such that a1= 1*0 a2= 2*1 : : an= n*(n-1) When we sum up the sequence of the first n numbers we obtain a series and therefore sn= a1+a2++an. Therefore; S1=0 S2=2 Sn= Sn-1+an Next, the difference between successive sums is made until the constant term in the series is obtained so long as the nth term n0, This will result to a polynomial of the third degree in order for the constant terms to be obtained in that the equation for the series will therefore be Sn = Ax3+Bx2+Cx+D where A,B,C and D are constants that are and xâ ± ¤ Now replacing x in the equation with the natural numbers 1,2,3,4,5.. we get the A+B+C+D=0 8A+4B+2C+D=2 27A+9B+3C+D=8 64A+16B+4C+D=20 This is a four equation system since there are four different unknown variables. Therefore we will use the graphing calculator to find the solutions to the unknown variables 1 1 1 1: 0 8 4 2 1: 2 27 9 3 1: 8 64 16 4 1: 20 We will find that A=1/3, B=0, C=-1/3 and D=0 Sn=1/3 x3-1/3 x The graph for the equation is therefore as follows Proving the equation by the induction method therefore will be (for n0); For n=1: =1/3*13 1/3* 1 =0 For n=3: =1/3*33 -1/3*3 =8 For n=5: =1/3*53 1/3*5 =40 Therefore we can assume that the equation is true for all values of natural number that is n0, We therefore assume that the equation is true for n=k Therefore for n=n+1, Sk+1= Sk+ (k+1)*k =1/3k3 -1/3k +k2 +k =1/3(k+1)3 -1/3(k+1) Since the expression is true for n=k+1 is true, the equation is true by induction. In the mathematical sense, a function of a polynomial p is normally written as p(x) =anxn+an-1+.+a1 x+ a0. In this case the n are non negative integers and the a’s are the coefficients of the polynomial itself. Usually all the polynomials have the domain of (-, ). In this case we can say that the linear functions themselves are polynomials of degree one while the quadratic functions are polynomials of the second degree and so on. As with our 33 matrix, the polynomial involved was a cubic function of the third degree. For instance the polynomial y=84-143-92+11x-1 Linear Algebraic Equations A teacher is looking for the best option in purchasing school supplies for a classroom. Company A is offering a discount for every dollar amount spent; Company B is offering a higher discount for every dollar spent above $20. Determine which company will offer a better price based upon the dollar amount the teacher spends on the school. In this scenario, it mostly involves the computation of the purchase of the school inventories at a cheaper price. Inventory generally is the stock of raw materials, work in progress units, finished goods, consumables and spare parts being held in store at a given time period. There are different kinds and groups of inventories that includes; movement inventories which are inventories on transit from one point to another, safety stock or the buffer stock which are the inventories that must always be maintained in the store so as to meet the unexpected demand, cyclical inventory, anticipatory inventory and the decoupling inventory. However, in this scenario we will focus on how to purchase inventory while at the same time using the mathematical knowledge to reduce inventory related costs. Here, the teacher is looking for the best option in purchasing school supplies for a classroom and therefore the best option is the option with reduced costs. The customer also has to ensure that tho ugh the goods are purchased at a cheaper price, they are of the best and desirable quality. The supplier of the goods should also be in a position to supply goods to the customer when they are needed both in the short term period and in the long term period and in time as to the date of the specifications. Therefore the customer has to look deep into these needs before making the decision on where to make their orders. The hypothetical customer, the teacher in this case has to make an informed decision based on questions such as how many units to order at that time, how often should the school supplies be made, how many orders are to be placed in that particular year and this is mainly done to reduce cost. In this scenario therefore we will focus mainly on two cost options that are for Company A which is offering a discount for every dollar spent. This is where a constant rate of discount for every dollar spent. This is where a constant rate of discount is offered irrespective of the number of units purchased and it is commonly known as a single discount. We will assume that the unit price of each product that is to be purchased is $5 and that the discount for every dollar spent is 5 percent (5%). In this scenario, the discount offered is for every dollar that will be spent and no conditions as to the amount and the limit of expenditure. The second option is for Company B which is offering a higher discount for every dollar spent above $20. This therefore guarantees the teacher discount after spending $20 in the purchase of school supplies which will be a much higher discount than that of the purchase of the goods worth $20. In this case the teacher will get a discount similar to that of the single discount up to the expenditure of $20 and later the discount is increased accordingly. We will therefore assume that the unit purchase price is $5 and that every dollar spent to the expenditure of $20 is 5%, with more dollars spent, the discount increases to 7.5%. In our scenario, the demand should be known in advance with certainty and will remain constant within the relevant range. The algebraic equations to represent the cost of each option are: Company A: Offers a discount for every dollar spent Here there are many cost related to the purchase of the school supplies which includes the purchase cost, the ordering cost, the holding cost and in some cases the shortage cost. However we will only focus on the purchase cost and ignore all the other related cost inorder to come up with the required linear equations. Let’s assume further that the teacher purchases x units of the school supplies Unit price = $5 Discount =5% Let the total cost=y Total purchase cost =$5 * (100% -5%) *x Total purchase cost = $5 *0.95 *x = 4.75x Company B: Offers a higher discount of 7.55 for every dollar spent above $20. The teacher here should know that for the first $20 spent, the discount is 5% and above the expenditure of $20, the discount increases to 7.5%. This will probably lure customers desire to purchase more but we will try evaluating the two equations. The equation for company B is therefore as follows Let’s assume that the teacher purchases x units of the school supplies The discount for the first 4 purchases of the school supplies =5% i.e ($20/5) Unit price =$5 Let the total cost=y The discount for the purchase of more than 4 =7.5% Total purchase cost = ($5*4*0.95) + ($5*0.925)(x-4) Total purchase cost = $19+4.625x –$18.5 =$0.5+4.625x The equation of company A is used since the company only offers a single discount for all the purchases that are made by the customer. Therefore the discount will be distributed equally. For Company B, there is a constant in the algebraic equation since in the purchase of the first $20 items, the discount is 5% that is it is constant and since the customer has to purchase more than this to gain the discount of 7.5% then that part of the equation will vary with the extra units purchased. The solution to the equation can be done through several ways such as elimination method, substitution method or the graphical method; the equations are normally written as y= 4.75x y= 0.5+4.625x We are going to solve the equation using the substitution method. Since in the first equation y=4.75x, we will substitute this to the second equation.4.75x= 0.5+4.625x and we therefore solve the equation mathematically. In this equation, the solution is x=4. Where the total costs will be the same. But with the increase in the purchase of the school supplies, the total cost will be higher for the purchase related to Company A than that of the purchase from Company B. Also, with the decrease in the purchase of the school supplies, the cost purchases from Company A are less than that of Company B. The graph of the two scenarios can be represented as follows. Though the cost associated in the two scenarios are close, there is a negligible difference as a result of the discounts. It is therefore correct to conclude that if the teacher is in need of less than four units of purchase, it is advisable to purchase the school supplies from Company A, if the teacher wants to purchase 4 units of item, this can be done from any company and if it is more than 4 company, it is cost effective to purchase from Company B. At the lower levels of purchase, presence of discount appears attractive for the company with a single discount for any unit of purchase made. That is, there is no constant related to the purchase of goods in the algebraic equation.. However beyond a certain level of purchase, taking up a discount results into a net increase in total cost in the company using a single discount method. In the other case for company with an increased discount after purchase of some discount, the purchase of many items become cost effective in this company. Therefore the teacher should ensure that he or she takes up the least quantity required to qualify for the highest discount in order for the total cost to be less than that of company A. Since the principle of discount states that only the least quantity required to qualify for the discount should be purchased.

Algebraic Operations on ACT Math Strategies and Formulas

Algebraic Operations on ACT Math Strategies and Formulas SAT / ACT Prep Online Guides and Tips Variables, exponents, and more variables, whoo! ACT operations questions will involve all of these (and so much more!). So if you ever wondered what to do with or how to solve some of those extra long and clunky algebra problems (â€Å"What is the equivalent to ${2/3}a^2b - (18b - 6c) +$ †¦Ã¢â‚¬  you get the picture), then this is the guide for you. This will be your complete guide to ACT operations questions- what they’ll look like on the test, how to perform operations with multiple variables and exponents, and what kinds of methods and strategies you’ll need to get them done as fast and as accurately as possible. You'll see these types of questions at least three times on any given ACT, so let's take a look. What Are Operations? There are four basic mathematical operations- adding, subtracting, multiplying, and dividing. The end goal for any particular algebra problem may be different, depending on the question, but the operations and the methods to solve them will be the same. For example, when solving a single variable equation or a system of equations, your ultimate objective is to solve for a missing variable. However, when solving an ACT operations problem, you must use your knowledge of mathematical operations to identify an equivalent expression (NOT solve for a missing variable). This means that the answer to these types of problems will always include a variable or multiple variables, since we are not actually finding the value of the variable. Let’s look at two examples, side-by-side. This is a single variable equation. Your objective is to find $x$. If $(9x-9)=-$, then $x=$? A. $-{92/9}$B. $-{20/9}$C. $-{/9}$D. $-{2/9}$E. $70/9$ This is an ACT operations problem. You must find an equivalent expression after performing a mathematical operation on a polynomial. The product $(2x^4y)(3x^5y^8)$ is equivalent to: F. $5x^9y^9$G. $6x^9y^8$H. $6x^9y^9$J. $5x^{20}y^8$K. $6x^{20}y^8$ (We will go through exactly how to solve this problem shortly) Let's break down each component of an operations problem, step-by-step. (Also, bonus French braid lesson!) Operation Question How-To's Let us look at how to identify operations questions when you see them and how to solve for your answer. How to Identify an Operations Problem As we said before, the end goal of an operations problem is not to solve for a missing variable. Because of this, you can identify an operations problem by looking at your answer choices. If the question involves variables (instead of integers) in the given equation and in the answer choices, then it is likely you are dealing with an operations problem. This means that if the problem asks you to identify an â€Å"equivalent† expression or the â€Å"simplified form† of an expression, then it is highly likely that you are dealing with an operations problem. How to Solve an Operations Problem In order to solve these types of questions, you have two options: you can either solve your problems by using algebra, or by using the strategy of plugging in numbers. Let’s begin by looking at how algebraic operations work. First, you must understand how to add, multiply, subtract, and divide terms with variables and exponents. (Before we go through how to do this, be sure to brush up on your understanding of exponents and integers.) So let us look at the rules of how to manipulate terms with variables and exponents. Addition and Subtraction When adding or subtracting terms with variables (and/or exponents), you can only add or subtract terms that have the exact same variable. This rule includes variables with exponents- only terms with variables raised to the same power may be added together (or subtracted). For example, $x$ and $x^2$ CANNOT be combined into one term (i.e. $2x^2$ or $x^3$). It can only be written as $x + x^2$. To add terms with variables and/or exponents, simply add the numbers before the variable (the coefficients) just as you would add any numbers without variables, and keep the variables intact. (Note: if there is no coefficient in front of the variable, it is worth 1. $x$ is the same thing as $1x$.) Again, if one term has an additional variable or is raised to a different power, the two terms cannot be added together. Yes: $x + 4x = 5x$ $10xy - 2xy = 8xy$ No: $6x + 5y$ $xy - 2x - y$ $x + x^2 + x^3$ These expressions all have terms with different variables (or variables to different powers) and so CANNOT be combined into one term. How they are written above is as simplified as they can ever get. Multiplication and Division When multiplying terms with variables, you may multiply any variable term with another. The variables do not have to match in order for you to multiply the terms- the variables instead are combined, or taken to an additional exponent if the variables are the same, after multiplying. (For more on multiplying numbers with exponents, check out the section on exponents in our guide to advanced integers) $x * y = xy$ $ab * c = abc$ $z * z = z^2$ The variables in front of the terms (the coefficients) are also multiplied with one another as usual. This new coefficient will then be attached to the combined variables. $2x * 3y = 6xy$ $3ab * c = 3abc$ Just as when we multiplying variable terms, we must take each component separately when we divide them. This means that the coefficients will be reduced/divided with regard to one another (just as with regular division), as will the variables. (Note: again, if your variables involve exponents, now might be a good time to brush up on your rules of dividing with exponents.) $${8xy}/{2x} = 4y$$ $${5a^2b^3}/{15a^2b^2} = b/3$$ $${30y + 45}/5 = 6y + 9$$ When working on operations problems, first take each component separately, before you put them together. Typical Operation Questions Though there are several ways an operations question may be presented to you on the ACT, the principles behind each problem are essentially the same- you must manipulate terms with variables by performing one (or more) of the four mathematical operations on them. Most of the operations problems you’ll see on the ACT will ask you to perform a mathematical operation (subtraction, addition, multiplication, or division) on a term or expression with variables and then ask you to identify the â€Å"equivalent† expression in the answer choices. More rarely, the question may ask you to manipulate an expression in order to present your equation â€Å"in terms of† another variable (e.g. â€Å"which of the following expressions shows the equation in terms of $x$?†). Now let’s look at the different kinds of operations problems in action. The product $(2x^4y)(3x^5y^8)$ is equivalent to: F. $5x^9y^9$G. $6x^9y^8$H. $6x^9y^9$J. $5x^{20}y^8$K. $6x^{20}y^8$ Here, we have our problem from earlier, but now we know how to go about solving it using algebra. We also have a second method for solving the question (for those of you are uninterested in or unwilling to use algebra), and that is to use the strategy of plugging in numbers. We’ll look at each method in turn. Solving Method 1: Algebra operations Knowing what we know about algebraic operations, we can multiply our terms. First, we must multiply our coefficients: $2 * 3 = 6$ This will be the coefficient in front of our new term, so we can eliminate answer choices F and J. Next, let us multiply our individual variables. $x^4 * x^5$ $x^[4 + 5]$ $x^9$ And, finally, our last variable. $y * y^8$ $y^[1 + 8]$ $y^9$ Now, combine each piece of our term to find our final answer: $6{x^9}y^9$ Our final answer is H, $6{x^9}y^9$ Solving Method 2: Plugging in our own numbers Alternatively, we can find our answer by plugging in our own numbers (remember- any time the question uses variables, we can plug in our own numbers). Let us say that $x = 2$ and $y = 3$ (Why those numbers? Why not! Any numbers will do- except for 1 or 0, which is explained in our PIN guide- but since we are working with exponents, smaller numbers will give us more manageable results.) So let us look at our first term and convert it into an integer using the numbers we selected to replace our variables. $2{x^4}y$ $2(2^4)(3)$ $2(16)(3)$ $96$ Now, let us do the same to our second term. $3{x^5}{y^8}$ $3(2^5)(3^8)$ $3(32)(6,561)$ $629,856$ And finally, we must multiply our terms together. $(2{x^4}y)(3{x^5}{y^8})$ $(96)(629,856)$ $60,466,176$ Now, we need to find the answer in our answer choices that matches our result. We must plug in our same values for $x$ and $y$ as we did here and then see which answer choice gives us the same result. If you are familiar with the process of using PIN, you know that our best option is usually to start with the middle answer choice. So let us test answer choice H to start. $6{x^9}y^9$ $6(2^9)(3^9)$ $6(512)(19,683)$ $60,466,176$ Success! We have found our correct answer on the first try! (Note: if our first option had not worked, we would have seen whether it was too low or too high and then picked our next answer choice to try, accordingly.) Our final answer is again H, $6{x^9}y^9$ Now let us look at our second type of problem. For all real numbers $b$ and $c$ such that the product of $c$ and 3 is $b$, which of the following expressions represents the sum of $c$ and 3 in terms of $b$? A. $b+3$B. $3b+3$C. $3(b+3)$D. ${b+3}/3$E. $b/3+3$ This question requires us to translate the problem first into an equation. Then, we must manipulate that equation until we have isolated a different variable than the original. Again, we have two methods with which to solve this question: algebra or PIN. Let us look at both. Solving Method 1: Algebra First, let us begin by translating our equation into an algebraic one. We are told that the product of $c$ and 3 is equal to $b$. A â€Å"product† means we must multiply $c$ and 3 and so our equation looks like this: $3c = b$ Now we are asked to find the sum of $c$ and 3. This means we must isolate $c$ so that we can add them together. So let us first isolate $c$ by using our knowledge of algebraic operations. $3c = b$ $c = b/3$ Now, we can sum $c$ and 3 by replacing our $c$ with $b/3$. $c + 3$ ${b/3} + 3$ Our answer matches answer choice E. Our final answer is E. Solving Method 2: Plugging in numbers Alternatively, we can use our technique of plugging in numbers. Because our question deals with variables, we can choose our own numbers (so long as they follow the rules of our given information.) We are told that the product of $c$ and 3 is equal to $b$. So let us assign a value to $c$ and use this information to find the value of $b$. So let us say that $c = 4$. (Why 4? Why not!) If $c = 4$, then the product of $c$ and 3 is: $3c = b$ $3(4) = b$ $b = 12$ So, when $c$ equals 4, $b$ equals 12. Now we must find the sum of $c$ and 3. $3 + c$ $3 + (4)$ $7$ Now that we have found our sum, we must identify the answer choice that gives us this sum. All of our answer choices are presented to us in terms of $b$, so we will use our found value of 12 to replace $b$ for each. As with all PIN questions, let us start with the middle answer option. Answer choice C gives us: $3(b + 3)$ We can tell just by looking at it that this will be far larger than 7, but we can always test this out. $3(12 + 3)$ $3(15)$ $45$ We can eliminate answer choice C. Just by glancing, we can see that answer choices A and B will also be larger than 12, which means we can eliminate them as well. Let us try answer choice D. ${b + 3}/3$ ${12 + 3}/3$ $15/3$ $5$ Answer choice D did not match our sum, which means we can eliminate it as well. By process of elimination, we are left with answer choice E, but let us test it to be sure. ${b/3} + 3$ ${12/3} + 3$ $4 + 3$ $7$ Success! We have found the answer choice that matches the sum we found. Our final answer is, once again, E, ${b/3} + 3$. As you can see, the answer to your operations questions will always be in variables and the problem will always require you to interpret and manipulate expressions with variables, but there are always multiple options for how to solve these types of problems. You've got the power to decide how you would like to solve and manipulate your operations problems. Magic! Strategies for Solving Operations Questions Now that we’ve seen the types of operations questions you’ll see on the ACT, let’s review our solving strategies. #1: Use PIN when needed (or to double-check your answer) If you ever feel concerned that you may be going down the wrong path while manipulating your operations problems, or if you simply want to double-check your answer, it's never a bad idea to use the strategy of plugging in numbers. Although it can take a little longer plug in your own numbers for your variables, you'll never have to fear misremembering how to manipulate your exponents, your variables, or your equations as a whole. Once you're able to use real numbers for your variables, the math will be a piece of cake. #2: Focus on one aspect of the term at a time It can become all too easy to lose yourself when working with multiple variables at once, especially when it comes to multiplication and division. The test-makers know this and will provide bait answers for any number of common mistakes. In order to keep all your components organized, focus on just one piece of each expression at a time. First, look at the coefficients, then look at the variables. This will help keep all your moving pieces in order and lessen the odds of mix-ups and mistakes. #3: Eliminate your answer options as you go Operations problems can sometimes mess with your head, not because they are inherently difficult, but because the ACT is a marathon and your brain can get tired and confused (and lazy). This, combined with the fact that all the answer choices generally look quite similar, with only small differences- a minus sign instead of a plus sign, one coefficient difference, etc.- can lead you to select the wrong answer, even when you know what the correct one should be. To avoid this kind of careless error (the worst kind of error!), eliminate your answer choices as you go through your problem. Know that the coefficient for your $y$ value must be 3? Immediately cross out any answer choices that give you anything other than $3y$. It may seem inefficient to solve problems this way, but it will keep your answers much more clear. #4: Keep careful track of your negatives Not only can it be difficult to keep track of multiple variables, but it's even easier to mix-up the proper negative and positive signs. Many students make careless errors with their negative signs and the ACT test-makers are all too aware of this. They will provide all manner of bait answers for anyone who misplaces even a single negative sign, so be very careful. $(a+2b+3c)-(4a+6b-5c)$ is equivalent to: A. $-4a-8b-2c$B. $-4a-4b+8c$C. $-3a+8b-2c$D. $-3a-4b-2c$E. $-3a-4b+8c$ For a problem like this, we are being asked to subtract the entire expression, $4a + 6b - 5c$, from the entire expression, $a + 2b + 3c$. This means that the negative sign will be negating every term in the expression $4a + 6b - 5c$. So we must put a negative sign in front of each term. $4a$ becomes $-4a$ $6b$ becomes $-6b$ $-5c$ becomes $- -5c$ or $+5c$. Now let us put these pieces together with the first expression. $a - 4a = -3a$ $2b - 6b = -4b$ $3c + 5c = 8c$ Our final expression will be: $-3a - 4b + 8c$ Our final answer is E, $-3a - 4b + 8c$. [Note: many (many!) students put a negative sign only in front of the first term in the parenthesis, which in this case the $4a$. If you had done this, you would have gotten: $a - 4a = -3a$ $2b + 6b = 8b$ $3c - 5c = -2c$. This would have given you answer choice C, $-3a + 8b - 2c$. Again the test-makers know this is a common error and there will always be a bait answer to tempt anyone who makes this kind of mistake.] Operations in the "real world." Hyuk, yuk, yuk. Test Your Knowledge Now that we’ve gone through the tips and tricks of operations questions, it’s time to put your knowledge to the test with more real ACT math problems. 1. Which of the following is an equivalent simplified expression for $2(4x+7)-3(2x-4)$? F. $x+2$G. $2x + 2$H. $2x+26$J. $3x+10$K. $3x+$ 2.Which of the following expressions is equivalent to ${1/2}y^2(6x+2y+12x-2y)$? A. $9xy^2$B. $18xy$C. $3xy^2 + 12x$D. $9xy^2-2y^3$E. $3xy^2+12x-y^3-2y$ 3.$t^2-59t+54-82t^2+60t$ is equivalent to: F. $-26t^2$G. $-26t^6$H. $-81t^4+t^2+54$J. $-81t^2+t+54$K. $-82t^2+t+54$ 4.The expression $-8x^3(7x^6-3x^5)$ is equivalent to: A. $-56x^9+24x^8$B. $-56x^9-24x^8$C. $-56x^18+24x^15$D. $-56^18-24x^15$E. $-32x^4$ Answers: H, A, J, A Answer Explanations: 1. As always, we can solve this question using algebra or using PIN. Let us look at both ways. Method 1: Algebra First, we must distribute out our terms. Only afterwards will we subtract them. Let us take each half of our expression by itself. $2(4x + 7)$ $8x + 14$ $ -3(2x - 4)$ $-6x + 12$ (Note: keep careful track of your negatives here, especially in the second half of our expression.) Now, we can put the two together. $8x + 14 - 6x + 12$ $2x + 26$ We cannot go any further, as we have combined all our like terms. Our final answer is H, $2x + 26$ Method 2: PIN As an alternative to algebra, we can always use plugging in numbers. So let us assign our own value to $x$, which we will call 3. (Why 3? Why not!) This means that we will replace any $x$ in our given equation with a 3. $2(4x + 7) - 3(2x - 4)$ $2(4(3) + 7) - 3(2(3) - 4)$ $2(12 + 7) - 3(6 - 4)$ $2(19) - 3(2)$ $38 - 6$ $32$ Now, let us find the answer choice that matches with our found answer of 32, once we replace the $x$ with 3. As usual, when using PIN, let us start with the middle answer option. $2x + 26$ $2(3) +26$ $6 + 26$ $32$ Success! We found our answer on the first try. But remember- when using PIN, always check your other answer options to make sure there are not repeat correct answers. We can see straightaway that answer choices F and G will be too small, since answer choice H was a match. So let us try answer choice J. $3x + 10$ $3(3) + 10$ $9 + 10$ $19$ This answer choice is too small and we can see just by looking that answer choice K will be too small as well (since they only differ by 1). This means we are safe with our answer choice H, as no others produced a match. Our final answer is H, $2x + 26$. As we saw from earlier in the guide and from the example problem above, we can always use algebra or PIN for our operations problems. Knowing that, we will only go through one method each for the rest of our answer explanations. 2: For this problem, let us do our solve using algebra (again, we could also use PIN, but for the sake of brevity, we are only choosing one method for each problem). We are given the equation: ${1/2}y^2(6x + 2y + 12x - 2y)$ Now, let us first make life easier by combining the like terms in the parenthesis. $(6x + 2y + 12x - 2y)$ $(6x + 12x + 2y - 2y)$ $(18x)$ The $y$ terms cancel one another out, so we are left with only $18x$ in the parenthesis. Now, we must multiply our $18x$ by ${1/2}y^2$. As always, when multiplying, we must multiply first the coefficients and then combine them with the combined variables. So: ${1/2}y^2 * 18x$ $(1/2) * 18 = 9$ $y^2 * x = y^2x$ Put the two together and we have: $9y^2x$ So our final answer is A, $9xy^2$ 3: Because we used algebra last time, let us try our hand at solving this question using PIN. Because we are using our own numbers, we don’t have to worry about whether or not we are matching up the right terms, or if we are combining them incorrectly; we can bypass all the mess and use numbers instead. We have one variable, $t$, so let us say that $t = 2$. (Why 2? As always, why not!) $t^2 - 59t + 54 - 82t^2 + 60t$ $(2)^2 - 59(2) + 54 - 82(2)^2 + 60(t)$ $4 - 8 + 54 - 328 + 120$ $-268$ Now, we must find the answer choice that matches our found answer of 102, once we replace $t$ with 2. Let us start in the middle, with answer choice H. $-81t^4 + t^2 + 54$ $-81(2)^4 + (2)^2 + 54$ $-81(16) + 4 + 54$ $-1296 + 58$ $-1238$ We can see just by looking that answer choice G will be too small as well ($-26 * 16 = -416$), and answer choice F will be too large (-26 * 4 = -104). So let us try answer choice J. $-81t^2 + t + 54$ $-81(2)^2 + 2 + 54$ $-81(4) + 56$ $-324 + 56$ $-268$ Success! And we can also see that the only difference between answer choices J and K are the coefficient in front of $t^2$ (-81 vs. -82), so we know that answer K would produce an incorrect and smaller number than answer choice J. Our final answer is J, $-81t^2 + t + 54$ 4: Because we used PIN last time, let us use algebra for this problem. Because we do not have like terms in the parenthesis, we must distribute out our expression using multiplication. $-8x^3(7x^6 - 3x^5)$ $-8x^3(7x^6) - -8x^3(3x^5)$ And take each piece separately. $-8x^3(7x^6)$ = $-8 * 7 = -56$ and $x^3 * x^6 = x^[3 + 6] = x^9$ (for more on this, look to the section on exponents in our advanced integers guide). So, combined, we have: $-56x^9$ And the other half of our expression will be the same. $- -8x^3(3x^5)$ $8x^3(3x^5)$ = $8 * 3 = 24$ and $x^3 * x^5 = x^[3 + 5] = x^8$ So, combined, we have: $24x^8$ Now our equation looks like this: $-56x^9 + 24x^8$ Our final answer is A, $-56x^9 + 24x^8$ (Take care! The only difference between answer choice A and B is the negative sign. If you weren’t careful with your double negatives, you may have fallen for this bait answer.) Ten thousand gold stars for solving your operations problems! The Take-Aways Though operations problems are easy to get wrong if you’re going too quickly through the test (or trying to solve them in your head), the basic elements are the same as any problem with variables- combine like terms, keep your work organized, and use PIN if you feel overwhelmed (or simply want to double-check your answer).

Middle east geography Essay Example | Topics and Well Written Essays - 500 words

Middle east geography - Essay Example Although Islam is the largest religion in the Middle East, the region also represents other faiths such as Christianity and Judaism. Survey reports indicate that Arabic, Persian, Turkish, Berber, and Kurdish are the major languages in the Middle East. While analyzing the region’s population growth trends, it is clear that Middle East has experienced a dramatic rise in population since 1970s. To illustrate, statistical reports (as reported by The New York Times, 2007), indicate that the region’s population increased from 127 million in 1970 to 305 million in 2005. During the period between 1976 and 1986, Iran’s population grew by 50%. According to a World Bank report, an annual population growth rate of 1.73 was reported in Middle East in 2010 whereas this rate was 1.75 in 2009 (Trading Economics, 2012). In many parts of the Middle East, average population growth rate is 3% or above; this trend indicates that population is a given state is likely to double in every 20 to 30 years (Imagery for Citizens, n.d). It is observed that high rate of population growth in the Middle East has serious impacts on the region’s social, economical, and political landscape. As a result of this issue, the Middle East governments struggle to provide necessary services to their people. This region is already suffering from water scarcity issues, and the high population growth has exacerbated the issues over water. As per the The New York Times (2007) report, rising population growth contributes to the region’s mounting needs of food imports; and in an attempt to respond to issues over water and food and search for improved living conditions, rural inhabitants heavily migrate to urban areas. This practice raises many potential challenges to urban infrastructure too. Similarly, huge population growth puts strains on the region’s economic landscape. As discussed earlier, the rising population growth has forced Middle East

Anishinabee social movment Essay Example | Topics and Well Written Essays - 500 words

Anishinabee social movment - Essay Example Through military expedition, the British tried to conquer the natives, but they were unsuccessful as the former migrated to various states in Canada. The biggest blow for Ojibway came when America got her independence from England. The new US government put an end to the Indian free movements. They were thus, confined in reservation areas with less hunting and fishing grounds and unlike their predecessors, Americans military force was more brutal and led to a lot of massacres. Through trickery and false accusations of Indian chiefs, Americans tried to contain the natives who they deemed hostile. However, military warfare seemed a futile way of trying to control the Indians as they were natural warriors. They therefore turned on indirect ways of ‘civilizing’ the natives. By the late 1800s, Indian children were accepted in large numbers into American schools. The strategy was to indoctrinate and incorporate American values and culture into the children while at the same time teaching them to abscond their native customs. Therefore, children were forbidden to speak their native language, their long hairs were cut short and their tribal regalia and medicine were openly burned. The ultimate result was children turned against their elders and customs. Indians were therefore forced to relocate to towns after they lost their lands. Currently, the situation is worse. Apart from the fact that Indian culture and history is deliberately ignored in the school system, the portrayal of the natives is shocking and false. The social, economic and political injustices that American Indians faced have been swept under the rug and what is taught in schools is utter nonsense that tries to justify the unjust occupation of Indian land. However, a recent crop of young Indians have begun retracing their roots. They are busy searching for elders who are accustomed to their olden

The growing importance of business ethics

The growing importance of business ethics This essay discusses the growing importance of business ethics in todays business world. It identifies and analyses the dilemma the multinational corporations are facing and the standards and principles they need to apply when facing these situations. It also identifies how a companys code of conduct can help it to achieve its ethical standards in its global market and create an image of a responsible company providing fair working environment and high ethical standards. In addition, It critically discusses the role and responsbilities that how an MNC can encourage ethical business practice in todays complicated and competitive business environment. The business world is becoming a global village. Various countries markets are becoming available to foreign investors and companies, this allows companies to go across the international borders to do business. It also results in greater competition and opportunities. Many companies become multinational corporations in this process. Multinational corporations are active and important players in todays international business. MNC refers to firms that have extensive and intensive involvement in global market, it also refers to firms that engage in foreign direct investment and own or control resources and activities in more than one country MNC generally coordinate their activities from a central headquarters, but may also allow their affiliates or subsidiaries in foreign markets considerable latitude in adjusting their operations to local circumstances. Businessmen nowadays are not merely satisfied with their home countrys markets and will go overseas to gain a market share in its global business. This leads to globalisation. Globalisation is defined as the expansion and deepening of ties across national borders, has gained ground in all aspects of the business environment. (Morrison, J 2006, p448) It enables individuals, corporations and organisations to reach around the world farther, faster, deeper and cheaper than ever before. It is the product of a particular form of governance rooted in the domestic political economies of the early industrialisers. (Prakash, A Hart, J 2000, p32) Some people argue that globalisation enables firms from developed countries to increase unemployment rate from their home countries by transferring job opportunities to a foreign country with low labour cost and serious environmental protection issue. According to the law of comparative advantage, the citizens of each nation can gain by spending more of their time and resources doing those things where they have a relative advantage. (Carbaugh, R, 2007, p14) Success in international trade comes from the interaction of four country-and firm-specific elements. Porters national competitive advantage Porters Diamond Factors conditions Includes not only land, labour, capital factors, also include factors such as educational level of workforces and infrastructure of a county Demand conditions A large and complicated domestic consumer demand would enable the country and companies to compete more effective and more competitively advantaged with other countries. -Related and supporting industries This includes industries supporting the main industry of the country. For instance, Swedens strong paper industry enables its country to have a strong truck manufacturing industry such as Scania. -Firm strategy, structure, rivalry This factor recognises the positive aspect of competition. Thus government might establish an environment that fosters such factors. The problem of international resource allocation, determinants of the pattern of world trade, and gains from trade, all relate to trade, profits and benefits. (Meier, G 1998, p417) However, when a MNC explores its foreign markets, there are cultural and ethical barriers. A MNC will have to encounter a variety of business practices, moral behaviour, ethical standards and cultures which are quite different from their home country. . The main dilemma is MNC are required to use more than their corporate code of conduct, they are also encouraged to apply a higher standard level of ethical business practice. Ethics are defined as the process of distinguishing the right and good from the wrong and bad, and they imply a moral duty to pursue the good and the right. Business ethics is the good or bad behaviour companies carry on in their business. It shows that business should act responsible rather than just seeking profit and economic gains. It forces the companies to adapt themselves in a more ethical and morally correct behaviour and enable companies not only consider profits also have to take the whole society into consideration such as environmental issue. A companys code of conduct sets out what a company can do and what a company cannot do. It establishes a level of business ethics when it operates both in host and home country. A MNCs ethical behaviour should be consistent in its global market. MNC should apply laws and ethical standards at home country and foreign markets where they operate. It should be followed consistently anywhere the MNC has its international business. A universal business ethics standard should be enforced for a MNC to the all the counties where it operates. Its ethical values and integrity should not be changed or damaged to pursue an economical gain or profit. The most important thing is that right ethical vales must be applied in anywhere in the world where the corporate operates its business no matter where it is. A good corporate code of conduct should have the following characteristics: a uniform standard of ethics in its global market set it as high and as practical as possible apply the code of conduct strictly and consistently employees should be fully aware of the code A strong code of conduct would assist a company to gain respect and support from its customers, local authorities even its competitors. To achieve success in todays competitive environment, a MNC should adopt a global standards and a common set of values which it can apply to everywhere it operates business. Besides establishing an ethical culture of a company, a good conduct code will also help the company to create an image of responsible and fairness in its global market. Moral principles might become a minor issue when a company explores its opportunities in a country where laws are not strong enforced and a fragile legal system exists. MNC might adopt a lower standard of moral behaviour in foreign countries where laws are not restrictive as in their home countries. The questions for MNC might be: Are we still going to stick into our principles? Are we going to accept and adapt ourselves to principles and standards that are lower than ours? A recent case is that Levi Jeans. It exited Chinas jean market a few years ago because of its notorious human rights records. The violation of human rights in China makes Levi in a dilemma whether it continues to operate in China or not. However, its global high standard of business ethics make it exited this major market because they cannot lower their moral standards so as to gain pure economic profits in China. In the world of business ethics today, the impact of ethical standards on MNC activities is becoming more and more important. As business ethics becomes more integrated into activities, we must pay attention to the risk of applying ethical standards from the home country to host country where MNC operates. For example, should an American company apply the same ethical behaviour and standard to a developing country such as Thailand? MNC also have to consider how to respect the local culture and apply to the ethical standards of the host country. An important problem for corporations is how to define ethical and unethical behaviour in a variety of countries. In todays world, the behaviour seems difficult to define and distinguish. If MNC apply correct behaviour, it would increase its image and reputation of good corporate governance, otherwise they will damage their reputations in its global market. As differences in the nature, methods, and scope of regulation highlight variations in models of economic organization, these can tighten trade tensions (Pollack, M Shaffer, G 2001p179) The more MNC interacts in a foreign market and country, the more they are going to testify whether their own values and moral judgment are right and absolute since the standards varies from one country to another. However, MNC should be aware that cultural differences and local traditions can be so different that they are contrary to MNC standard in their home country to a large extent. An MNC is usually expected to find itself unprepared in dealing with ethical behaviour in a foreign country. Even if the problems are the same in a foreign country, the ways to solve it might be different. A typical example here is gift-giving. In many countries and cultures, gift giving is allowed and tolerated. For example, in Japan, give giving is not unethical and often encouraged. It represents a kind of relationship between business and business or business and governments. This is quite different from the perspective of western society or ethical standards. This clearly illustrates the importance of nature of differences between different counties and cultures when evaluating different practices, while MNC have to consider whether it complies with its global ethical standards and principles. The main ethical dilemma here is what kind of ethical behaviour should MNC adopts when values conflict with another. Should a company invest in a country where weak labour laws exist or environmental issues are not considered seriously? Or should a company invest in a country where bribery is a common practice? Business ethics can help employees to be prevented from exploitation by profit seeking companies. It is quite clear that some activities are unethical and would not be tolerated no matter where it happens. For instance, forced labour should not be allowed in anywhere in the world. A recent case is that in Thailand, almost 200 people were killed in an international toy manufacturing factory. The cause of the deaths not only pointed to the ineffective sprinkler system, it also because the management level the facotory locked employee in the factory and eventually caused 200 deaths. This kind of behaviour should not be allowed and tolerated in any ethical standards and norms. Responsibilities of MNS to encourage ethical business practice Bribery issue There are two kinds of corruptions: State Capture Individuals, organizations, corporations exercise their power to influence the formation of regulations and policies to benefit themselves to some extent, usually achieved by bribing government officials Administrative corruption Government official use their power and influence to force companies, individuals, groups to pay certain fees by distorting laws and regulations. MNC will often encounter different practices, standards of business behaviour and cultures. They might face the situation that whether to bride a local government official in order to obtain a business contract or deal. A major and common problem in todays international business is how MNC can deal with bribery. In theory, there is no any country on this planet would allow businessmen to bribe government officials and officials are not allowed to take bribe offered by a businessman. However, in practice, this happens quite often. Corruption is a mutual mechanism. Corruption will never happen without demand and supply. Many MNC said that they would not accept and tolerate any kind of bribery. They would prefer not to compete for the business contracts if bribery has to be taken in the whole process. In many developing and less developed countries (LDC), a main problem is that the rising of corruption and bribery in local governmental bodies is leading to both politital and social instability. This problem is more prevalent and serious in these developing or less developed countries law enforcements are not so strong or undeveloped. Child labour issue Another main unethical practice facing MNC is the use of child labour. The labour market difficulties in developed countries are important and deserve full consideration (Michie, J 2003, p194) In most developed countries, use of child labour morally not allowed and more importantly it is prohibited by legislation. Hence, MNC operates in developing and LDC countries are expected to apply the same standards and rules. However in some countries in the world, use of child labour are often allowed and sometimes encouraged. Children are often expected to help their parents to sustain financial problem. This has been a culture or tradition in those countries. This is mainly because of the poor education provided by the local government and insufficient funds to help those children to be well educated. In this instance, children would not be able to survive if they do not work. MNC have to face these situations when they operate in these countries. In these countries, child labour is encouraged to have economical gains. Further, because these societies often do not have the finance, facilities and manpower to provide necessary and appropriate education, children would not be able to survive if they do not work. In Europe, it is concerned with the upheaval caused by globalisation. It must determine how best to use education and training to commit European countries to a process of job creation, whilst ta king control of the globalisation and economy. (Prakash, A Hart, J 2000 p90) However, for MNC, they should not employ children without assessing the consequences. A detailed analysis should be conducted by MNC to assess whether children are suitable to conduct work for them. In addition, they should also provide a fair and safe working environment for those children. Another effective way is to work and cooperate with the local government to provide necessary education and ensure children have necessary education and training before they can start in the workforce. Conclusion: Multinational corporations have become an important and active role in todays globalisation. They have strong power and influences on a foreign countrys policies, regulations even legal issues. The way how they perform in a foreign market has become quite important for both the home country and host country it operates. The moral and ethical standards and principles MNC applies overseas should be consistent with those standards in their home countries. They have a strong responsibility to encourage, promote and apply a globally consistent ethical standards and principles.
