You keep getting 79 because that's the answer silly!
Answer:
1. 
2. 
Step-by-step explanation:
1. Solution for 1st part.
Given:
Ben shared his post with 2 friends
Each of those friends shares with 3 more every day.
the number of shares triples every day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

2. Solution for part 2.
Given:
Carter shared his post with 10 friends.
each share with only 2 people each day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

Answer:
x^12
Step-by-step explanation:
Answer:
$613.04
Step-by-step explanation:
<em>Compound Interest Formula:</em>
n = number of compounds
t = time
r = interest rate
P = principle amount (original amount)
A = final amount
Since it's compounded quarterly, that means there will be 4 compounds per year, so n=4. The interest rate has to be converted to the decimal value, and this is done by simply dividing it by 100 to get r=0.06.

Answer:

Step-by-step explanation:
We find slope by; change in y ÷ change in x,
Change in y = -4 - 3 = -7
Change in x = 7 - - 2 = 9
Slope of line MN = -7 ÷ 9 =
