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

height of zinger 1 after 6 second=6(-16×6+150)= -96×6+900

height of zinger 2 after 6 second=6(-16t×6+165)= -96×6+990

zinger 2 is 90 units higher than zinger 1
