Suppose the height of a cylinder is 2155.13 ft cubed and the height is twice the radius of the cylinder. determine the radius, rounded to the nearest whole foot. you in advance : )

The radius is 7 feet.

Step-by-step explanation:

I am assuming you meant to write volume of a cylinder is 2155.13 ft cubed.

The general formula for volume of a cylinder is

with r the radius, and h the height. We are given V=2155.13 ft^3, and h=2r:

The radius is 7 feet.

i think c. but don't trust it.

step-by-step explanation:

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! : )
