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:
2,6
Step-by-step explanation:
2 2/3 means 2 + 2/3
2 2/3 = 8/3
8/3 = 2,6
So 2 2/3 = 2,6
Answer:
Five times nine plus twenty
Step-by-step explanation:
Just remember the order of operations... multiplication and division are done first before adding and subtracting.
Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b

a∆b=
=3
Similarly, for the right hand side.

Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
