Question

the height y of a baseball thrown by a child is

y = 1/10x^2 + 3x + 6

where x is the horizontal distance in feet from where the ball was thrown. Will the ball fly over the head of another child 30 feet away trying to catch the ball. The child who is trying to catch the ball holds a baseball glove at a height of 5 feet.

Answer 1

y = 0.1*30² + 3*30 + 6 = 186

Yes. Sign that kid to a major league contract. In fact, the ball will continue to rise forever.
