A model rocket is launched from the deck in Jim's backyard and the path followed by
the
rocket can be modeled by the relation h = -5t^2 + 100t + 15, where h, in metres, is
the
height that the model rocket reaches after t seconds.
a) What is the height of the deck?
b) What is the height of the model rocket after 2 s?
c) What is the maximum height reached by the model rocket?
formula:
x=
-b ± √b² - 4ac
2a
