A soccer ball is kicked from the ground with an initial upward velocity of 90 feet per second. The equation h=-16t^2+90t gives the height "h" of the ball after "t" seconds.

Find the maximum height of the ball.

126.56 feet

This can be found by finding the vertex of the parabola. You can find the t value using -b/2a and then plug that in to find the h value.
