Given:

The height of an object project upward is given by the polynomial

where t represents the time, in seconds.

We need to determine the height after t = 2.5 seconds.

Height of an object:

The height of an object after 2.5 seconds can be determined by substituting t=2.5 in the polynomial, we get;

Simplifying, we get;

Thus, the height of an object is 140 feet.
