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.

<u>Explanation:</u>
x² - 8x + 19
a=1 b=-8 c=19
Use the Quadratic formula to find the solutions for x:






= 4 ± i√3
Solutions are: Factors are:
x = 4 + i√3 x - (4 + i√3) = 0
x = 4 - i√3 x - (4 - i√3) = 0
