Answer:
The answer to your question is t = 50 s
Explanation:
Data
Function
H(t) = -t² + 100t + 100
Process
1.- Find the derivative of the function to get the maximum
H'(t) = -2t + 100
2.- Equal to zero the derivative
-2t + 100 = 0
3.- Solve for t
-2t = -100
t = -100/-2
t = 50 s
4.- Conclusion
It takes 50 s to reach the maximum height
