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.1So you get the time = 1.5 d(1.5) = 85 * 1.5 = ?
