The given equation ⇒⇒⇒ h(t)=−16t² + 115t +15
Represents the height of a toy rocket, in feet, t seconds after it is launched from a platform.
So, at t = 0 ⇒⇒⇒ h(t)=−16 * (0)² + 115 * (0) +15 = 15
At t = 0 represents the height at the instant of launching the toy rocket and it is equal to the height of the platform.
∴ The height of the platform = 15 feet
