WORD PROBLEM USING VERTEX FORM
The flight path of a firework is modeled by the relation h=-5(t-5)2+127 where h is the height, in metres, of the firework above the ground and t is the time, in seconds, since the firework was fired.
a) What is the maximum height reached by the firework?
The maximum height is 127 m.
b) How many seconds after it was fired does the firework reach this height?
The firework reaches 127 m after 5 seconds.
