Question 148067: s(t)=-16t^2+75t+407, Where t is the number of seconds elapsed. How long will it take the ball to reach a height of 450 feet above the ground? You may use the Quadratic formula or completing the square. You might get two answers. Think about this: 450 feet may not be the highest elevation it gets. Unless 450 is the highest (think vertex), then it will reach that height as it comes up, reaches it again as it comes down. Round your answer(s) to the nearest tenth!
