<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>
