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

Zinger 1 = -16(6)^2 +150(6) = 324 feet

Zinger 2 = -16(6)^2 + 165(6) = 414 feet

414-324 = 90 feet

Zinger 2 is 90 feet higher
