If f(x) = 3x + 2 and g(x) = x^2 + 1, which expression is equivalent to (f . g)(x)? a. (3x + 2)(x^2 + 1).
b. 3x^2 + 1 + 2
c. (3x + 2)^2 + 1.
d. 3(x^2 + 1) + 2.

d

Step-by-step explanation:

for this function you have to replace the function of g(x) where there's x in the function f(x) that's what the expression f.g(x) means and so this is going to be

3(x²+1)+2

I hope this helps

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
