Answer and Step-by-step explanation:
7.
The <u>volume</u> of a cylinder is , in which:
r = radius
h = height
d = 2 × r
will equal 3.14.
Plug it in to the equation.
18990.72 is the answer. (2nd Answer choice)
8.
x = -2
Expression is:
Plug -2 in for x.
1 is the answer choice. (1st Answer choice).

the function f(x) = 4(x+3) − 5
Lets find the inverse function f^-1(x)
step 1: Replace f(x) with y
y = 4(x+3) − 5
step 2: Replace x with y and y with x
x = 4(y+3) - 5
step 3: Solve for y
x = 4(y+3) - 5
x = 4y +12 -5
x= 4y + 7 (subtract 7 on both sides)
x - 7 = 4y (divide by 4 on both sides)
Given : x = 3
We plug in 3 for x in the inverse function
= -1
the inverse function when x = 3 is -1
