Question 313975: A baseball player throws a ball from the outfield toward home plate. The ball's height above the ground is modeled by the equation y =16x^2+48x+6, where y represents height, in feet, and x represents time, in seconds. The ball is initially thrown from a height of 6 feet. how many seconds after the ball is thrown will it again be 6 feet above the ground? what is the maximum height, in feet, that the ball reaches?

Question 314607: Jack throws a ball straight up in the air. The equation, h(t)= 16tsquared+64t+5 gives the height (in feet) of the ball from the ground t seconds after it is thrown. How long does it take for the ball to hit the ground?
I have already figured out the maximum height, I think, as 75 feet. Which takes 5 seconds.
Thanks.
