Answers A and <span>D
</span><span>
</span><span>9x − 3(x+8) [distribute] = 9x − 3x − 24 = 6x − 24 [combine like terms]
</span>
<span>8(x−3)−2x = [distribute] 8x−24−2x = 6x−24 [combine like terms] </span>
<span>It is required to find the highest altitude (in meters) .
</span>
For the given <span>quadratic function ⇒⇒ A(t) = −(t − 11)² + 115</span>
From the attached figure which represents the graph of the given function
the maximum will be at point (11,115)
So, <span>
the highest altitude (in meters) = 115 meter</span>
<span>
and it will reach it at t = 11 </span><span>
seconds</span>
