Consider the function f(x)=2x+6x^(-1). For this function, there are three numbers A<B<C which are either critical or not in the domain of the function. A= B= C=

The function crosses the origin so I see it as A = ∫ x(x^2+16)^(1/2) dx from 0 to 3 = [ (1/3)(x^2+16)^(3/2) ] from 0 to 3 = (1/3)(25)^(3/2) - 0 = (1/3)(125) = 125/3

Solve the equation 2x + 5y - 3z = -1. Write the general solution as a matrix equation. I did some guessing and ended up getting this much: [x]= [-1/2 _ _ ] X  [y]= [ 0 1 0 ] X [s] [z]= [ 0 0 1 ] X [t] however I still can't figure out the last two values in the first row

I still don't really understand how to do it... I did some guessing and ended up getting this much: [x] [-1/2 _ _]  [y]= [0 1 0] X [s] [z] [0 0 1] [t] however I still can't figure out the last two values in the first row.

In the interval (0 is less than or equal to x which is less than or equal to 5), the graphs of y=cos(2x) and y=sin(3x) intersect four times. Let A, B, C, and D be the x-coordinates of these points so that 0<A<B<C<D<5. Which of the definite integrals below ...

If you are asking what it is, consider this: u=INT (x-c)^n * f(x) dx is the definition of the nth moment about the mean c. so in math, u=INT xf(x)dx is the first moment about the y axis (xo=c=0). That is the definition, if that is what you were looking for. To calculate it, as...
