A company bought a total of 412feet of cable to connect 3 computers to the wall outlet. Each computer needs the same amount of cable. How many feet of cable are needed to connect each computer?

Each computer needs 3/2, or 1.5 feet of cable

Step-by-step explanation:

Firstly, we need to divide 4 1/2 by 3

Then we can make 4 1/2 an improper fraction.

We will also multiply 4 by 2 and then add 1

= 8 + 1

= 9

But;

9/2 = 4 1/2

In order to divide 9/2 by 3/1, we will change 3/1 to 1/3 and then multiply

= 9/2 × 1/3

= 9/6

= 3/2 or 1.5

Therefore, each computer needs 3/2, or 1.5 feet of cable.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

the answer is 8/21

hope this
