The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.
The given parameters;
- s(t) = -9t² + 103t + 403
- time interval (4.499, 4.5), and (4.5, 4.501)
The average velocity of the bottle rocket over the intervals is calculated as follows;
when the interval = [<em>4.499, 4.5</em>]
when the interval = [<em>4.5, 4.501</em>]
The instantaneous velocity of the bottle rocket at time t=4.5;
Thus, the average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

Hoods become necessary any time water temperatures drop below: 20°C/68°F.
<h3>Why is it necessary to use
Hoods any time
water temperatures drop below:
20°C/68°F?</h3>
It is important to use hood so as to adjust the cold temperature, so as to be able to gain heat.
Therefore, hood serves as a covering for the head as well as the neck which has a opening face that prevent cold.

Answer: D) The Continental army faced defeat most times they fought the British.
Explanation:
I got it right
The answer would be B., because the Practice SAT is not designed to help students practice presentation skills.
There is no part that requires presentation in the PSAT!
It is a test of multiple choice in the areas of English and Math
