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 -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? 414 ft

90 ft

324 ft

990 ft

    Answer:

    90 feet

    Step-by-step explanation:

    If we put t  = 6 into both the formulas, we will get the height of each.

    Zinger 1:

    Height = -16t^2 + 150t

    Putting t = 6,

    -16(6)^2 + 150(6)=324

    Zinger 2:

    Height = -16t^2 + 165t

    Putting t = 6,

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

    The difference in height is 414 – 324 = 90 feet
