Gi is standing on the top of a 275 feet building she throws a ball straight up into the air. the balls velocity is given as 48 ft/sec. the height, in feet, of the ball after t seconds is given by h=-16t^2+48t+275. a. how long will it take for the ball to reach its maximum height above the ground? b. what is the maximum height that the ball reaches? c. how many seconds does it take for the ball to finally hit the ground? (round answer to the nearest tenth of a second)

John is hitting baseballs. the height of the ball is given by y=-16x^2+25x+5 (x is seconds, y is height in feet) 1.) what is the original height of the ball hitting the bat? 2.) what is the maximum height that the ball reaches? 3.) how long does it take for the ball to reach its maximum height? 4.) when does the ball hit the ground? find the vertex of the parabola. 1.) k^2-56=k 2.) b^2+10b=-24
