uadratic Equation Word Problem. A model rocket is launched from the deck in Janes backyard and the path followed by the rocket can be modelled by the relation h = -5t^2 + 100t + 15, where h, in meters, is the height that the model rocket reaches after t seconds. What is the height of the deck? What is the height of the model rocket after 2s? What is the maximum height reached by the model rocket and when does it reach the height? How long was the model rocket above 200m
