<PRE><B>Question 937420</B>
A placekicker kicks the football, which reaches a maximum height of 8 yards and lands 50 feet away. Assuming the football was at the origin when it was kicked, write and equation for the height of the football.
-------------------
Draw the picture.
x-intercepts at (0,0) and (50,0)
---
high point = (25,8)
----
Form:: y = ax^2 + bx + c
y = ax(x-50
8 = a*25(-25)
a = 8/-625
------
-b/(2a) = 25
b = -50a = -50[-8/625] = 400/625 = 16/25
-----
c = 0
------------------
Equation::
y = (-8/625)x^2 + (16/25)x
--------------------------
