0.07 is 7 hundredths, and can be represented as 7/100.
7/20 = 35/100 (or 0.35) 35/100 ≠ 7/100.
Multiplying both the top and bottom by the same number, the ratio will not change, like how one half, 1/2, is equal to two quarters, 2/4.
Using geometric sequence concepts, it is found that:
a) The rule is:
.
b) An exponential relationship exists between the two variables.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
![a_n = a_1q^{n-1}](https://tex.z-dn.net/?f=a_n%20%3D%20a_1q%5E%7Bn-1%7D)
In which
is the first term.
A geometric sequence represents an exponential relationship between the variables.
In this problem, considering that the first-place finisher wins half of $1.500.000 in total prize money, and each finisher earns half of the one who finished above, the first term and the common ratio are given by:
.
Hence the nth term of the sequence is given by:
![P_n = 750000(0.5)^{n-1}](https://tex.z-dn.net/?f=P_n%20%3D%20750000%280.5%29%5E%7Bn-1%7D)

Answer:
-2a-4n+14
Step-by-step explanation:
A. 696 - take 1200 (the population of the school) and multiply by the result you found (.58 or 58%). 1200 * .58 = 696
