Answer:
-5/2
Step-by-step explanation:
The average rate of change is the slope of the line between the two points. You can see from the graph that the slope is ...
slope = rise/run = -5/2
The average rate of change on the interval is -5/2.
You would convert one of the units to the other, then find the ratio between them when they are the same.
Example: 2 inches and 10 centimeters
1 inch = 2.54 cm
2 x 2.54 = 5.08
10 / 5.08 = 1.969
10 cm is 1.969 times longer than 2 inches.
Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:
This is the same as: 
Example 1:
We are trying to find what to raise 9 to, in order to get a result of 9.
When you have same bases, you equal exponents.
Therefore; 
Example 2:
In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: 
which is 2*2*2*2*2
Rewriting this example we have;
Since we have the same base, we equal exponents.
Therefore; 
Example 3:
729 can have a base of 3 if expressed as: 
We can use PEMDAS to help us:
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
PEMDAS states what occurs first in order of which letter pertains to which mathematical operation and how you are suppose to do it from left to right. Since multiplication and division comes before addition and subtraction, we know C isn't the answer since it is subtraction. This leaves us with A, B, and D. They all happen to be either multiplication and division. Although multiplication SEEMS to come before division, multiplication and division are actually paired together (just like addition and subtraction) meaning that if either a multiplication or division comes before a division and multiplication operation, you do it left to right. For example, 2 x 2/2. You do 2 x 2 first equaling 4 and then divide by 2 to get 2. Another example is 10/2 x 5. You DO NOT do multiplication first since multiplication and division are paired together meaning you do 10/2 equaling 5 and then do 5 x 5 equaling 25. Enough explanation for that part. Since 20/4 is the first multiplication/division operation, that is what you do first. The answer is A.
