<h3>
Answer: Choice C</h3>
=================================================
Explanation:
For choice C, the x values are out of order, so it might be tricky at first. I recommend sorting the x values from smallest to largest to get -2, -1, 0, 1, 2. Do the same for the y values as well. Make sure the correct y values stay with their x value pairs. You should get the list of y values to be 4, 2, 1, 1/2, 1/4
Check out the attached image below for the sorted table I'm referring to
We can see the list of y values is going down as x increases. This is a good sign we have decay. Further proof is that we multiply each term by 1/2 to get the next one
4 times 1/2 = 2
2 times 1/2 = 1
1 times 1/2 = 1/2
1/2 times 1/2 = 1/4
and so on. Effectively we can say the decay rate is 50%
The expression that represents the cost of y books is 12y + 3.
Given that,
- The charge for the first copy of the book is $15.
- For each extra copy, the charge is $12.
- Here we assume the number of books be y.
Now based on the above information, the expression should be
= 12y + (15 - 12)
= 12y + 3
Therefore we can conclude that option F is correct.

The geometric mean of 8 and 253 is;
<h3>Geometric mean of numbers</h3>
According to the question;
- The task requires that the geometric mean of 8 and 253 be determined.
The geometric mean of a two numbers is the square root the product of the he numbers.
Hence, in this scenario;
The geometric mean of 8 and 253 is;
G.M = 45.
Ultimately, the geometric mean of 8 and 253 is approximately 45.

Answer:
Interest rate is 5.25% a year.
Step-by-step explanation:
r = (1/54)((22252.5/18000) - 1) = 0.004375
r = 0.004375
Convert decimal to percentage
R = 0.004375 * 100 = 0.4375%/month
Calculate annual rate
0.4375%/month × 12 months/year = 5.25% per year.
Non linear means not a straight line so answer C or the third answer.
