Question 1056328
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 -16t^2 + 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?
:
Replace t with 6 sec in the given formulas
diff in height = (-16(6^2) + 165(6)) - (-16(6^2) + 150(6))
-16(6^2) cancel each other, so we are left with
d = 165(6) - 150(6)
d = 990 - 900
d = 60 ft
