an object is thrown off a platform that is 15 ft high with an initial velocity of 8.5 ft/is what function models the height h of the object after t seconds

Therefore the function that models the height of the object after t seconds is given by "H (t) = 15 + 8.5*t + 16.09*t²".

Step-by-step explanation:

Since the object has a initial velocity and it's being accelerated by gravity, than it's height is defined by:

H (t) = H (0) + V (0) * t + 0.5*g*t²

Applying the data from the problem, we have:

H (t) = 15 + 8.5*t + 0.5*32.17405*t²

H (t) = 15 + 8.5*t + 16.09*t²

Therefore the function that models the height of the object after t seconds is given by "H (t) = 15 + 8.5*t + 16.09*t²".
