Answer:
y = (x - 2)² + 9
Step-by-step explanation:
To obtain the equation in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 13
= (x - 2)² + 9 ← in vertex form
Answer:
c = 43.96
Step-by-step explanation:
First you have to find the diameter of the trampoline which would be 14

The question would be:
Which is the best measure of center for first period and why?
