Answer:
3.6 x 10^3
Step-by-step explanation:
<u>Given</u>:
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.
<u>Height of an object:</u>
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.
Say you have the fraction 1/2 to the power of 2, so 1/2^2. You could also write this down as: 1/2*(times)1/2 or 0,5*0,5. Whenever you multiply by a number smaller than one, the outcome will get smaller. Whenever you multiply by a number larger than one, the outcome will be larger.
