Option 1 is correct. The correct solution about these functions is that The original population of State A was double of the original population of State B.
How to solve for the solutionThe function in the question is given as
For A:
[tex]F(x) = 4*(1.08)^x[/tex]
For B
[tex]g(x) = 2*(1.08)^x[/tex]
The exponential growth equation that is used to solve this is
[tex]h(x) = A(r)^x[/tex]
such that A is the initial and r is the rate of growth.
f(x) and g(x) are at the same rate but the exponential function is known to grow faster.
Hence the correct option is The original population of State A was double of the original population of State B.
Complete question:Which conclusion is correct about the population of State A and State B? 1. The original population of State A was double of the original population of State B.
2. The original population of State A was half of the original population of State B.
3. The original population of State B was one-fourth of the original population of State A.

so that BM = CN. Prove:
∆BAM ≅ ∆CAN
∆AMN is an isosceles triangle.
From the statements and reasons given below as regards the Isosceles Triangle, we have been able to prove that; ∆BAM ≅ ∆CAN
How to prove an Isosceles Triangle?Isosceles Triangle means that two sides of the triangle are equal and also 2 angles are equal.
Now, we are told that triangle ABC is an Isosceles and as such, AB and AC are congruent.
We are given that BM and NC are congruent. Now, due to the fact that Triangle AMN is an isosceles triangle, it means that the sides AM and AN are congruent to each other.
Thus, from the proofs above and from the definition of the isosceles Triangle, we can say that triangles BAM and CAN are congruent.

Answer & Step-by-step explanation:
To prove ∆BAM ≅ ∆CAN:
1. Given that ∆ABC is an isosceles triangle with base BC, and BM = CN, we know that AB = AC.
2. Using the Side-Angle-Side (SAS) congruence criterion, we can show that ∆ABM and ∆ACN are congruent.
3. Therefore, corresponding angles ∠BAM and ∠CAN are congruent.
4. Similarly, ∠BMA and ∠CNA are congruent.
5. By showing that corresponding angles in ∆ABM and ∆ACN are congruent, we can conclude that ∆BAM ≅ ∆CAN.
To prove ∆AMN is an isosceles triangle:
1. From the given information, we know that BM = CN.
2. By proving ∆BAM ≅ ∆CAN, we have shown that ∠BAM ≅ ∠CAN.
3. Since ∠BAM and ∠CAN are congruent, we can conclude that ∠BAN ≅ ∠CAM using the Transitive Property of Congruence.
4. By establishing that ∠BAN ≅ ∠CAM, we can conclude that ∆AMN is an isosceles triangle because it has two congruent angles.

From a group of 13 women and 12 men, a researcher wants to randomly select 8 women and 8 men for a study. In how many ways can the study group be selected?
The total number of ways the study can be selected is: 637065
Given,
Total number of women in a group= 13
Total number of men in a group = 12
Number of women chosen = 8
Number of men chosen = 8
∴ the total number of ways the study group can be selected = 13C₈ and 12C₈.
This in the form of combination factor = nCr
∴ nCr = n!/(n₋r)! r!
13C₈ = 13!/(13 ₋ 8)! 8!
= 13!/5!.8!
= 1287
12C₈ = 12!/(12₋8)! 8!
= 12!/5! 8!
= 495
Now multiply both the combinations of men and women
= 1287 × 495
= 637065
Hence the total number of ways the study group is selected is 637065

x = 2 , y = 3Step-by-step explanation:
As the given figure is a rectangle, therefore the opposite sides should be equal. So -
3x + y = 12 – y...(eqn (i) )
and
y – x = x – 1...(eqn (ii) )
Solving eqn (ii) we get -
→ y – x = x – 1
→ y = x + x – 1
→ y = 2x – 1...eqn(iii)
Solving eqn (i) we get -
→ 3x + y = 12 – y
→ 3x = 12 – y – y
→ 3x = 12 – 2y
Substituting the value of eqn (iii)
→ 3x = 12 – 2(2x– 1)
→ 3x = 12 – 4x + 2
→ 3x + 4x = 14
→ 7x = 14
→ x = 14/7
→ x = 2
Hope it helps you!!Answer:
x = 2; y = 3
Step-by-step explanation:
Since the quadrilateral has 4 right angles, it is a rectangle.
In a rectangle, opposite sides are congruent.
3x + y = 12 - y
x - 1 = y - x
We have a system of two equation is 2 variables.
Let's simplify both equations.
3x + 2y = 12
2x - y = 1
Rewrite the first equation. Multiply both sides of the second equation by 2. Add the equations.
3x + 2y = 12
(+) 4x - 2y = 2
-------------------------
7x = 14
Divide both sides by 2.
x = 2
Substitute 2 for x in the second original equation and solve for y.
x - 1 = y - x
2 - 1 = y - 2
1 = y - 2
y = 3
Answer: x = 2; y = 3

find the quotient: -10/9 divided by -5/7
Answer:
70/45
Step-by-step explanation:
(-10/9) divided by (-5/7) = (-10/9) / (-5/7)
dividing two fractions is the same as multiplying the top fraction by the reciprocal of the bottom one
top fraction = -10/9
bottom fraction = -5/7
reciprocal just means switching the numerator and denominator
reciprocal of bottom fraction = 7 / -5 = -7/5
thus,
(-10/9) / (-5/7) = (-10/9) * reciprocal of (-5/7) = (-10/9) * (-7/5) = 70/45
note that to multiply two fractions, you just multiply the numerators to get your new numerator and do the same thing with the denominators

A radioactive element has a half-life of 55 days. what percentage of the original sample is left after 115 days? round to 4 decimals when necessary.
The percentage of the radioactive isotope left is 25.0000%.
What is the half life?The half life of a radioactive isotope is the time that will elapse before only half of the number of original isotopes will remain.
Now;
We are told that;
Half life (t1/2) = 55 days
Time taken (t) = 115 days
Ratio of isotope remaining = N/No
Thus;
N/No = (1/2)^t/t1/2
N/No = (1/2)^115/55
N/No = (1/2)^2
N/No =1/4
