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:You answered 19 questions correctly and 1 question wrong
Step-by-step explanation:First you have to divide 20 by whatever number that can get you to the number 100 by 20,which is 5(100 divided by 5 equals 20)Lastly you have to divide 95 by 5 and you get 19!
Answer: 1. HA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
2. HL can be a reason to show given triangles are congruent as the triangles are right triangle with equal legs and hypotenuse.
3. SAS can be a reason to show given triangles are congruent as there are two congruent sides in both triangles and included angles ∠A=∠D=90° [right angle].
4. LA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
5. AAS cannot be a reason to show given triangles are congruent as it is not given that they have two angles common in both the triangles.
6.SSS can be a reason to show given triangles are congruent as it is shown that all the sides of one triangle is congruent to the other.

Answer:
The mean length of the 13 people's big finger is 15.45 cm
Step-by-step explanation:
Given;
mean length of 4 childrens' big finger, x' = 14cm
mean length of 9 adults' big finger is 16.1cm, x'' = 16.1cm
Let the total length of the 4 childrens' big finger = t
![x' = \frac{t}{n} \\\\x' = \frac{t}{4}\\\\t = 4x'\\\\t = 4 *14\\\\t = 56 \ cm](https://tex.z-dn.net/?f=x%27%20%3D%20%5Cfrac%7Bt%7D%7Bn%7D%20%5C%5C%5C%5Cx%27%20%3D%20%5Cfrac%7Bt%7D%7B4%7D%5C%5C%5C%5Ct%20%3D%204x%27%5C%5C%5C%5Ct%20%3D%204%20%2A14%5C%5C%5C%5Ct%20%3D%2056%20%5C%20cm)
Let the total length of the 9 adults' big finger = T
![x'' = \frac{T}{N} \\\\x'' = \frac{T}{9}\\\\T = 9x''\\\\T = 9*16.1\\\\T = 144.9 \ cm](https://tex.z-dn.net/?f=x%27%27%20%3D%20%5Cfrac%7BT%7D%7BN%7D%20%5C%5C%5C%5Cx%27%27%20%3D%20%5Cfrac%7BT%7D%7B9%7D%5C%5C%5C%5CT%20%3D%209x%27%27%5C%5C%5C%5CT%20%3D%209%2A16.1%5C%5C%5C%5CT%20%3D%20144.9%20%5C%20cm)
The total length of the 13 people's big finger = t + T
= 56 + 144.9
=200.9 cm
The mean length of these 13 people's big finger;
x''' = (200.9) / 13
x''' = 15.4539 cm
x''' = 15.45 cm (2 DP)
Therefore, the mean length of the 13 people's big finger is 15.45 cm
