The equation h(t) = −16t^2 + 115t + 15 gives the height of a toy rocket, in feet, t seconds after it is launched from a platform. What is the height of the platform?
Given that the height of the rocket at time t after it was launched is given by: h(t)=-16t^2+115t+15 the height of the platform which the rocket was launched from will be given by the intercept of h(t), at the intercept, t=0 thus plugging t=0 in the function we get: h(0)=-16(0)^2+115(0)+15 h(0)=15
