Answer:
1)The rocket hit the ground at     
2)The maximum height of the rocket = 12.468 feet
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equation  
                 y = -2 x² + 5 x + 7 ...(i)
Differentiating equation (i) with respective to 'x' , we get
              
 Equating zero 
             
⇒      -4 x +5 =0
⇒      -4 x = -5
⇒           
 
<em> The rocket hit the ground at     </em> <em></em>
<em></em>
<u><em>Step(ii):</em></u>-
      ...(ii)
  ...(ii) 
Again differentiating equation (ii) with respective to 'x' , we get
  
The maximum height at x = 
   y = -2 x² + 5 x + 7
  
 
 
<em>The maximum height of the rocket = 12.468 feet</em>
