Part A A toy cannon ball is launched from a cannon on top of a platform. The equation h(t) = –5t2 + 30t + 8 gives the height h, in meters, of the ball t seconds after it is launched. What equation can be used to tell whether the ball reaches a height of 34 m?

A. –5t2 + 30t + 8 = 0

B. –5t2 + 30t + 8 = 34

C. –5t2 + 30t + 4 + 34 = 0

D. –5t2 + 30t + 4 = t + 34
