The height y, in feet, of a football x seconds after it is thrown is modeled by the equation y = �16x2(squared) + 24x + 1.
----------------------------------------------
What information does the solution of the equation 6 = �16x2(squared) + 24x + 1 represent?
========
-16x^2+24x+1 = 6 means the ball is at a height of 6 ft.
----------
Solving::
16x^2 - 24x + 5 = 0
-------
x = 1.25 seconds (time at which the ball is 6 ft above the ground)
