Answer:
60
Step-by-step explanation:
The given function is:

The average rate of change of h(t) from t=a to t=b is given by:

We can rewrite this function as: 
The maximum height of the rocket is 231 and it occurs at t=3.75

The initial launch occurs at: t=0
and 
The average rate of change from the initial launch to the maximum height is

Answer:
Step-by-step explanation:
The associative property states that you can add or multiply regardless of how the numbers are grouped.
Answer:
The answer is the letter B.
The first column represents the x-values, and the second row represents the y-values.
For that reason, if we have:
2x - 7y = -1
x + 3y = -5
Then, the matrix will be given by:
[ 2 -7
1 3]
Then, the third colum will be the equality:
[ -1
-5]
So the correct option is the letter B.
1. x+9
2. (b-5)+6
3. 15+5v
4. 2/3k
