Lucy tosses a ball up to Carry, waiting at a third-story window, with an initial velocity of 30 feet per second. She releases the ball from a height of 6 feet. The equation h=-16t^2+30t+6 represents the height, h, of the ball after t seconds. If the ball must reach a height of 25 feet for Carry to catch it, does the ball reach Carry? Explain.

(Hint: Substitute 25 for h and use the discriminant.)
