Answer:
the equation is (y-3)^2 = 4(x+3)
The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be 226.08 square feet.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Ellis is painting wooden fenceposts before putting them in his yard. They are each 6 feet tall and have a diameter of 1 foot. There are 12 fenceposts in all.
The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be
The area of the one fence post will be
Area = πdh
Area = 3.14 x 1 x 6
Area = 18.84 square feet
Then the paint for 12 fence posts will be
Total area = 12 x 18.84
Total area = 226.08 square feet

Answer:
y was not substituted for every x
Step-by-step explanation:
To find the inverse of ...
y = f(x)
you need to solve ...
x = f(y)
Here, f(x) = x^2 +12x, so f(y) = y^2 +12y
This is not the expression we see on the right of ...
x = y^2 +12x
Apparently y was not properly substituted into f(x).
I believe the correct answer is (D). Because it stands for donuts and I like them
