3. 147  4.

Step-by-step explanation:

3. Volume of a square pyramid = ×

Variables:

V = volume

x = base edge length

h = height

V =  ×

x = 7 ft

h = 9 ft

Plug the values in the equation:

V = ×

V = 49 × 3

V = 147

4. Volume of cone =

Variables:

V = volume

r = radius

h = height

V =

r = 8ft /2 = 4 ft (radius is half of the diameter)

h = 10 ft

V =  

V = × 16 ×

V =

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! : )
