1. Jamie throws a ball to her sister, who is standing on a third-story balcony with her hands 38 feet above the ground. If Jamie throws the ball with an initial velocity of 40 feet per second, the equation h=-16t2 + 40t + 5 gives the height h of the ball after t seconds. · How long does it take the ball to reach its highest point? · How high does the ball reach? · Will her sister be able to catch the ball? Explain. 2. A player hits a baseball at a 45 degree angle with the ground with an initial velocity of 80 feet per second from a height of three feet above the ground. The equation h=-0.005x2 + x +3 gives the path of the ball, where h is the height and x is the horizontal distance the ball travels. · What is the equation of the axis of symmetry? · What is the maximum height reached by the baseball? · An outfielder catcher the ball three feet above the ground. How far has the ball traveled horizontally when the outfielder catches it? Holliday, B., Cuevas, G., Moore-Harris, B., & Carter, J. (2005). //Algebra 1//. New York, New York: Glencoe McGraw Hill.
