Answer:
Step-by-step explanation:
The max is a point with coordinates (-b/2a, s(-b/2a))
s(t) = - 4t ² + 237t + 744
-b/2a = -237 /2*(-4)= 237 / 8 ≈29.625
s(237/8) = -4(237/8)² +237*237/8 +744
= -(237²/ 16 ) +(237²/8 ) +744
≈4254.563
The time when the maximum height is reached is t ≈ 29.625 seconds
The maximum hight is at s(t) ≅4,254.563 feet
