F(x) = 3x + 2 and g(x) = x + 5

g[f(x)] =

A. 3x + 7
B. 3x + 17
C. 4x + 7

A

Step-by-step explanation:

g[f(x)]=g(3x+2)=3x+2+5=3x+7

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 !

unless if u could do my questions, if not i wouldn't want to
