## Suggested Questions And Answer :

### what is each part of the equation y=mx+b mean and who do you find them using math vocabulary

The normal meaning for this standard linear equation is that x and y are coordinates in a rectangular arrangement of axes. The y axis is North-South while the x axis is East-West. Where they cross is called the origin with coordinates (0,0), that is, x and y are both zero. The equation y=mx+b defines a straight line. It slopes at a value given by m, the slope or gradient, and m is a number which can be a whole number, a fraction, or whatever, as long as it is constant so that the line remains straight. The slope, m, is also known as the tangent, and the tangent of the angle that the line makes with the x axis has a value of m. When the straight line is at an angle of 45 degrees to the x axis, its tangent is 1 so m=1. If the line slopes backwards at 45 degrees to the x axis, it's tangent is -1 and m=-1. Forward sloping lines have a positive m, while backward sloping lines have a negative m. The value of b is also called the y intercept, because it's the point on the y axis where the straight line crosses that axis. It can have a positive or negative value. b is a constant, just like m. mx is m times x. The x axis is divided by equally spaced numbers, 0, 1, 2, 3 etc to the right, and -1, -2, -3 etc to the left of the origin. The y axis is similarly divided, postitive numbers going up and negative numbers going down. By putting numbers in the equation you can work out where points go on the line. m will have a value, like 2, for example, and b a value, say, 3, so we have y=2x+3. If we put x=0 we get y=3 which is the y intercept. So we mark that point (0,3) by going up 3 divisions on the y axis. Now put x=1, then y=5. So we move to the point (1,5), which is right 1 and up 5. We can join that point to (0,3) and continue beyond these points. What we find is that, although we have only plotted two points, other values of x and y actually fit on the line. If we look at where x=3 and go up to meet the line, then go horizontally back to the y axis, we should find it meets the point 9 on the y axis. So the line represents the relationship between x and y as given by the equation for all points including points in between our whole number divisions, like, for example, 1.5 or one and a half, halfway between 1 and 2.

### how do u turn a fraction into a decimal using bar notation?

First of all bar notaiton means to put a bar on top of a or any numbers that repeat in decimal form. An example: 2/3 = .666666666......repeating so we write it .6 with a bar on top of the 6. Since the 6 repeats. Keep in mind when working with  fractions:  2/3 MEANS 2 divide by 3. If you can use a calculator this is actually the best method.  Keystrokes would be: 2                                      Divide symbol                                      3                                     = Should be .666666......number of 6's depends on number of places your calculator displays. Just write .6 with a bar on top of the 6.  In case you forgot or don't know: To change a mixed fraction into a single fraction such as 3 1/4. 1.   4 * 3     Multiply denominator (bottom number) with whole number (3)  which equals 12. 2. 12 + 1  Now ADD that 12 to the numerator (Top number) which is 1. That equals 13  this is your NEW numerator  Your denominator is the same which is 4 Therfore, your single fraction is 13/4 If you have a calculator you can compare. Take 13/4 = 3.25 which in decimal form is 3 1/4.   I hope this covers it. I hope this wasn't too confusing. Sorry if it was.

### solving for x

I interpret the first number in brackets as the base.You need a calculator to do this because, although the bases 2 and 4 are related to one another because 4 is 2 squared, there's no easy relation between 2 and 3, 3 and 10, or 2 and 10. 10 in base 2 is approximately 3.322; log 2 in base 10 is approximately 0.3010 which is the reciprocal of 3.322. Log 3 in base 2 is approximately 1.585 and log 2 in base 3 is 0.6309 which is the reciprocal of 1.585. Log 4 to base 2 is 2 so log 2 to base 4 is 0.5. To convert log x in one base to another we use the conversion factor of the log of one base of the other base. Let's choose base 2 as the common base. This is what the equation becomes: 0.5logx+logx+logx/log3=logx/log10. Put y=logx (base 2) and we get 0.5y+y+0.6903y=0.3010y. If we were to divide through by y we would have an inequality because 2.1903 is not equal to .3010. Therefore y=0 and logx=0, so x=1. That was the longwinded way of proving the solution. We can see that x=1 makes all the terms in the original equation zero and 0=0 is always true! Why go to all the trouble of using a calculator when the only answer is x=1? It was just possible that the sum of the numbers on the left side of the equation came to the result on the right side of the equation, in which case we would have had an identity instead of an equation, which would have been true for all values of x (except x=0).

### if i have a positive base and negative exponset the solution positive or negative

Of course, you can always get a quick answer by trying some examples in your calculator.  But that wouldn't be much fun, would it?  :) Let's consider a positive base of 2. Clearly, 2^1 =                           2                2^2 =            2 * 2 =   4                2^3 =       2 * 2 * 2 =   8                2^4 = 2 * 2 * 2 * 2 = 16 and so on. . . Notice that everytime the exponent increases by 1, the answer gets twice as big. Now, run things in reverse.  What happens every time the exponent decreases by 1? Clearly, we divide by 2 each time.  We go from 16 -> 8 -> 4 ->2. So, if 2^1 = 2, what would you expect 2^0 to equal? Hopefully, you can see that we simply divide by 2 again to get from 2 to 2/2 = 1. Continuing this pattern of dividing by 2 when the exponent decreases, we get. . . 2^-1 = 1/2 2^-2 = 1/4 2^-3 = 1/8 etc. Notice that each time, the number gets closer to 0 each time (in fact, twice as close), but it never changes sign.  Hopefully, you see that we can divide by 2 as many times as we want and we'll never change sign.  We'll just get closer to 0. If we had a different base than 2, then we would just be dividing by a different positive number each time the exponent decreased.  But no matter how many times you divide by a positive number--when you start with a positive number, the result will remain positive. So, in general, a positive number raised to a negative exponent will always be positive. Hope this helps!

### integral from 0 to infinity of (cos x * cos(x^2)) dx

The behaviour of this function f(x)=cos(x)cos(x^2) is interesting. The integral is the area between the curve and the x axis. If the functions cos(x) and -cos(x) are plotted on the same graph, the latter form an envelope for f(x). Between x=(pi)/2 and 3(pi)/2, the curve has 4 maxima and 3 minima; between x=3(pi)/2 and 5(pi)/2 there are 7 maxima and 6 minima; between x=(2n-1)(pi)/2 and (2n+1)(pi)/2 there are 3n+1 maxima and 3n minima (integer n>0), a total of 6n+1. (These are based purely on observation, and need to be supported by sound mathematical deduction.) As n becomes large the envelope appears to fill as the extrema become closer together. As x tends to infinity n also tends to infinity. The envelope apparently has as much area above (positive) as below (negative) the x axis so the total area will be zero as the positive and negative areas cancel out. The question is: do the areas cancel out exactly? As x gets larger, the curve starts to develop irregularities and patterns, but it stays within the envelope, and positive irregularities appear to be balanced by negative irregularities, so the overall symmetry appears to be preserved. f(x)=0 when cos(x)=0 or cos(x^2)=0, which means that x=(2n-1)(pi)/2 or sqrt((2n-1)(pi)/2), where n>0. Between 3(pi)/2 and 5(pi)/2, for example, we have sqrt(3(pi)/2), sqrt(5(pi)/2), ..., sqrt(13(pi)/2), because sqrt(13(pi)/2)<3(pi)/20, and this lies between (2n-1) and (2n+1); so n is defined by 2n-1<(2m+1)^2(pi)/2<2n+1.  For m-1 we have 2(n-z)-1<(2m-1)^2(pi)/2<2(n-z)+1, where z is related to the number of zeroes in the current "batch". For example, take m=3: 2n-1<49(pi)/2<2n+1; 49(pi)/2=76.97 approx., so 2n-1=75, and n=38. Also 2(n-z)-1<25(pi)/2<2(n-z)+1 so, because 25(pi)/2=39.27 approx., 2(n-z)+1=41, n-z=20, and z=18. When m=2, 2n-1=39, n=20; 2(20-z)-1<9(pi)/2<2(20-z)+1; 2(20-z)-1=13, 20-z=7, z=13. The actual number of zeroes, Z, including the end points is 2 more than this: Z=z+2. Now we have an exact way to calculate the number of zeroes in each batch. So Z and n are both related to m. The number of extrema, E=Z-1=z+1. In fact, E=int(2(pi)(m-1)+1), where int(a) means the integer part of a, so as m increases, there are proportionately more extrema over the range (2m-1)(pi)/2 to (2m+1)(pi)/2. The figure of 6n+1 deduced earlier by observation approximates to the mathematical findings, because 2(pi) is approximately equal to 6. But we still need to show, or disprove, that the areas above and below the x axis are equal and therefore cancel out. Unfortunately, if we consider the area under the first maximum (between x=(pi)/2 and sqrt(3(pi)/2)), and the area above the first minimum (between x=sqrt(3(pi)/2) and sqrt(5(pi)/2)), they are not the same, so do not cancel out.

### how to evaluate expression

The quadratic x^2+10x+23=0 has roots -5+sqrt(2). We can write the quadratic x(x+10)=-23, so x=-23/(x+10). We can bring in sqrt(2) iteratively: put x=-5 into the expression on the right: x=-23/5=-4.6. Then we put x=-4.6 into the expression so we have x=-23/5.4=-4.259259... Put x=-4.259259 into the expression we get x=-4.0064516, and then we get x=-3.83746, and so on until after numerous iterations (repeating the process) we get to -3.585786438. This is very close to one of the roots of the equation, in other words -5+sqrt(2). The initial value of -5 guides the process to this root rather than the other root. Therefore, we can evaluate sqrt(2) by adding 5 to this number: 5-3.585786438=1.414213562. This iterative process can be performed by a calculator by repeatedly putting the value of x back into the same expression to get the next value of x. Some calculators allow you to build up an expression and keep applying it iteratively as you get each approximation. Using this method you can see the values converging until you reach the accuracy limits of the calculator and you get an unchanging result. You can apply this method using x=1/(x-2). Start with x=1, then you get x=-0.5, then -0.4, then -0.4167 up to -0.4142135624. Then you add 1 to get sqrt(2). This gives you a more accurate answer because we have an extra digit 4 at the end. The iterative process can give you slightly better accuracy than simply working out sqrt(2) directly on your calculator.

### How many different distributions can the manager make if every employee receives at least one voucher?

There must be 100 vouchers because each is worth RM5 and the total value is 500 ringgits or RM500. (i) Each employee receives at least 1 voucher, so that means there are 95 vouchers left to distribute. We can write each distribution as {A,B,C,D,E}: starting with {0,0,0,0,95}, then {0,0,0,1,94}, {0,0,0,2,93}, ..., {0,0,0,95,0}, {0,0,1,0,94}, ..., {0,0,95,0,0}, ..., ..., {95,0,0,0,0}. So when A=B=C=0, {D,E} range from {0,95}, {1,94}, ..., to {95,0}, 96 ways. When A=B=0 and C=1, {D,E} range from {0,94} to {94,0}, 95 ways. Finally when C=95 so {C,D,E}={95,0,0} we will have covered 96+95+...+1=96*97/2=4656 ways. (The sum of the whole numbers from 1 to n is given by S=n(n+1)/2.) That was for B=0; when B=1, {C,D,E} ranges from {0,0,94} to {94,0,0} to cover 95*96/2=4560 ways. When B=2 it's 94*95/2=4465 ways. So for A=0 we have 4656+4560+4465+...+3+1 = 96^2+94^2+...+2^2 = 4(48^2+47^2+46^2+...+2^2+1^2)=4*48*49*97/6=152096 (the sum of the squares of the whole numbers from 1 to n is given by S=n(n+1)(2n+1)/6. Also, the sum of whole numbers between 1 and n taken in pairs gives us: n(n+1)/2+(n-1)n/2 for each pair. This is n^2/2+n/2+n^2/2-n/2=n^2. For the next pair we get (n-2)^2 and so on.) That was just for A=0! For A=1 we have {1,0,0,0,94} to {1,94,0,0,0}. This will give us 4560+4465+...+10+6+3+1 = 95^2+93^2+...+5^2+3^2+1. There is a formula for this sum. It is S=(n+1)(2n+1)(2n+3)/3, where 2n+1=95, so n=47. So for A=1, the number of ways is 48*95*97/3=147440. For A=2 we have {2,0,0,0,93} to {2,93,0,0,0} which produces 94^2+92^2+...+4^2+2^2 = 4(47^2+46^2+...+1) = 4*47*48*95/6 = 142880. So we alternate between two formulae as A continues to go from 3 to 95.  More to follow...

### Polynomial Functions

Polynomial functions are functions that have this form: f(x) = anxn + an-1xn-1 + ... + a1x + a0 The value of n must be an non-negative integer. That is, it must be whole number; it is equal to zero or a positive integer. The coefficients, as they are called, are an, an-1,..., a1, a0. These are real numbers. The degree of the polynomial function is the highest value for n where an is not equal to 0. So, the degree of
