A baseball player hits a ball toward the outfield. The height h of the ball in feet is modeled by h(t) = 16t2 + 22t + 3, where t is the time in seconds. In addition, the function d(t) = 85t models the horizontal distance d traveled by the ball. If no one catches the ball, how long will it stay in the air?

Best ResponseYou've already chosen the best response.0im also suppose to find out what the horizontal distance that the ball travels before it hits the ground? I got 127.5 can anyone tell me if im wrong?

Best ResponseYou've already chosen the best response.0So you get the time = 1.5 d(1.5) = 85 * 1.5 = ?
