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:

Your answer to this is
V= a²
Answer:
-68
Step-by-step explanation:
X/17=-4
X=-68
So the answer is -68
This is the concept of financial arithemetic;
We are required to calculate the total cost of leasing a new luxury car.
Here we shall use the formula;
total cost=[deposit+title fee+licence]+(monthly payment*number of months)
deposit=$658
title fee=$105
license=$80
monthly payments=6000
number of months=60
thus;
total cost=[6000+105+80]+[658*60]
total cost=6185+39,480
total cost=$45,665
Answer:
x=6
Step-by-step explanation:
Since y=7 when x=2, we can from here simplify and see that y=3.5 when x=1. If y=21, then we multiply 7 by 3 which is 21, and since we must keep a proportion, we must multiply 2 by 3 and get 6 as the answer.
