Question

The path of a marble rolling off of a desk can be modeled by the parametric equations:
x (t) = 2.5t
y (t) = -16t² +3
In these equations, the horizontal and vertical positions of the marble z (t) and y (t) are in feet and t is measured in seconds. Use Desmos and scratch paper to complete the following prompts.
