Question

A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t2 + 150t gives the height in feet of Zinger 1 at t seconds after launch. The polynomial -16t2 + 165t gives the height of Zinger 2 at t seconds after launch. If the rockets are launched at the same time and both explode 6 seconds after launch, how much higher is Zinger 2 than Zinger 1 when they explode?

Answer 1

t=6
Zinger 1: -16 * t^2 + 150 * t = -16 * 6^2 + 150 * 6 =324
Zinger 2: -16 * t^2 + 165 * t = -16 * 6^2 + 165 * 6 = 414

414-324=90

Answer 2

so substitute t = 6 into each equation

so zinger 1 h(6) = - 16*(6)^2 + 150 * 6

zinger 2 h(h) = -16*(6)^2 + 165 + 6
