Give answers to the nearest hundredth. Graphed 1.5 and 35 e) Determine the y-intercept, by graphing (2nd - trace - value, x = 0) Graphed : 2 Use the following information to answer the next 3 questions. The height in feet, h, of a ball thrown in the air after t seconds is modeled by the equation h(t) =-16t2 + 48t +3. 20. What is the maximum height that the ball reaches? (2nd - trace - max, y-coordinate) 1. To the nearest tenth, how long does it take for the ball to reach the maximum height? (2nd - trace - max, x-coordinate) 22 seconds 2. To the nearest hundredth of a second, how long is the ball in the air? (2nd - trace - zero)
