Question 1085745


{{{h = -16t^2 +60t}}} where {{{t}}} is the time in seconds.

A. Factor the expression.

{{{H = -16t^2 + 60t = 4t (-4t + 15)}}}

B. What is the height of the rocket after {{{2}}} seconds?
When {{{t = 2}}}
{{{H = 4*2(-4*2 + 15) = 8(-8+15)=8(7)=56}}}

C. What is the height of the rocket after {{{3.75}}} seconds? Explain the solution.
When {{{t = 3.75}}}
{{{H = 4*3.75(-4 * 3.75 + 15) =15(-15+15)=15*0 =0}}}
The Bottle Rocket should have landed after {{{3.75 }}}seconds.
