Question

A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t^2 +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

if -16t^2 +150t gives the height after t seconds, what is the height after 6 seconds, for zinger 1?

Answer 2

lets take a simpler example. suppose you are traveling at 10 feet per second, what does that mean?

Answer 3

I think i figured it out.
zinger2 -zinger1 = (-16t^2 +165t) - (-16t^2 +150t) = 15t
then plug in 6
15*6 = 90

Answer 4

exactly! very good!
