6. Write the equation of the parabola in vertex form.

A. y = x2

B. y = 1/4x^2 + 1

C. y = 1/4x^2

D. y = 1/4( x - 2)^2 + 1

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.

answer is  

minor arc – sw

major arc – stu

semicircle – wst

i got it down chief.

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
