Y=x^2-5, solve for x
y+5=x^2
x=√(y+5) so
f^-1(x)=√(y+5)
SA of a cylinder: 2

r² + 2

rh
r = radius of base
h = height of cylinder
Plug in 3 for r and 5 for h in the formula.
2

3² + 2

(3)(5)
Use a calculator to solve.
2

3² + 2

(3)(5) =
150.8 ft²
Answer:
z = 6
Step-by-step explanation:

The equation is x=-6
Step-by-step explanation:
In standard form the equation is y=4
And this is a horizontal line so the perpendicular line will be a vertical line of the form x=a
so that is why the equation is x=-6
