Answer:
1/3
Step-by-step explanation:
The average rate of change of a function f(x) on an interval [a, b] is given by the formula ...
rate of change = (f(b) -f(a))/(b -a)
__
For the given function and interval, this is ...
(log₂(4·8) -log₂(4·2))/(8 -2) = (5 -3)/(6) = 1/3
The average rate of change is 1/3.
_____
In the attached graph, the line between the points at the ends of the interval can be seen to have a rise of 1 for a run of 3. Its slope is 1/3.
12 times 3.14 = 37.68 CM
C=D x 3.14
Answer: 
Step-by-step explanation:
You have the following information given in the problem:
- The number of soccer fans that are going to a soccer game is 27.
- A ticket to the game costs $18 per person.
- The cost of the lunch for all 27 fans is $172.
-
represents the total cost of attending the game for all 27 fans.
Therefore, keeping the above on mind you can write the following expression that closely estimates the total cost of attending the game for all 27 fans:

1. 11; 4
2. -64; 81
3. X+5; x+22,500
4. -13; -3
5. 8
6. 56F; 6F
7. -29/10 or -2 and 9/10
8. >; <; <
9. -2/9
