While the vertex of the function f(x) = x^2 is (0, 0), the vertex of the function g(x) = x^2 + 2x + 1 is (-1, 0).
Whereas both function has same y-cordinate, their x-coordinate are different which indicates that the function g(x) = x^2 + 2x + 1 is a horizontal translation of the function f(x) = x^2.
Answer:
Answer: The percentage increase is 78.68%
Step-by-step explanation:
There are two acceptable ways of solving this. I'll show both (just in case one of them doesn't align with the information from your textbook).
Option 1 (fast and easy):The following is the equation for the area of a regular pentagon with side length s.

Plug s=12 into the equation.


The third choice should be your answer.
Option 2 (much more complicated):The area of a regular polygon can be solved with the following formula.

Let's solve for the apothem.
A pentagon can be divided into 5 congruent isosceles triangles. The vertex angle will be 360/5, or 72 degrees.
An isosceles triangle can be divided into two right triangles. One of the angles of the right triangle will be 72/2, or 36 degrees.
The leg opposite of the 36 degree angle will be 12/2, or 6 inches long.


The apothem is about 8.26 inches.
The perimeter is 12*5, or 60 inches.



(it seems that we're off by 0.1 due to rounding errors)
The answer is the third choice. Hope this helps! :)
