Answer:
The relation represents a growth when b>1 and a decay when 0<b<1
Step-by-step explanation:
Any function in the form 
, where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b. If 0 < b < 1. It is an example of an exponential decay. The general shape of an exponential with b > 1 is an example of exponential growth. An exponential function is expressed in the form 
The relation represents a growth when b >1 and a decay when 0<b<1.
Um well its quite common when going to the store and something is 50% off
Answer: 2.01%.
Step-by-step explanation:
Suppose Alex invests $1 into the account for one year. The formula is A=P0⋅(1+rk)N⋅k with P0=$1. We know that r=0.02 and k=2 compounding periods per year. Now, N=1 year. Substituting the values we have A=$1⋅(1+0.022)2=$1.0201. Now, to calculate the effective annual yield, we will use the formula rEFF=A−P0P0. rEFF=1.0201−11=0.0201 or 2.01%. When rounded to two decimals, rEFF=2.01%. However, do not include the % in your answer.
Answer:
Yes
Step-by-step explanation:
First you pull them into the equation
2(-4)-5(3)=-23
Distribute
-8-15=-23
-23=-23
Answer:
r + 7 is a factor.
Step-by-step explanation:
You have to divide 
by r + 7. If the remainder is 0, then r + 7 is a factor of .
I did that and the remainder was 0.
So, yes, r + 7 is a factor.
You will need to learn how to do that division in order to solve this problem. OK?
