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.

Answer:
Yes
Explanation:
The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
For a normal distribution with a mean of μ and standard deviation σ, For any sample size (n) drawn from this population, the sample mean is normally distributed, with mean 
and standard deviation 
.
Hence given that a mean of μ = 20.6 years and standard deviation σ = 5.3 years, for a sample size of 100:
mean 
and standard deviation 
.
The question requires that we identify the past continuous form of the sentence. The answer to the question will be:
- When we were in the middle of our sleep, a burglar broke into our house.
The past continuous form of a sentence describes an action that started sometime in the past and continued for a while after it began.
The sentence above describes a past continuous sentence because it described an action that was ongoing sometime in the past.
