Each of two savings accounts begins with $975 as an initial deposit and 5.4% annual interest rate; however, the interest is accrued distinctly for each account. As demonstrated below in Table I:
- Savings Account A: A = 975 * (1 + 0.054 / 12) ^ (12 * t);
- Savings Account B: A = 975 * (1 + 52.65 * t).
Thus, after eight years, which account will yield a higher balance and why remains to be determined?

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of 5.9% per hour.
How many hours does it take for the size of the sample to double?
Note: This is a continuous exponential growth model.
Do not round any intermediate computations, and round your answer to the nearest hundredth.
Answer:
11.72 hours
Step-by-step explanation:
In a continuous exponential growth model, the formula for the size of the population at time t is given by:
N(t) = N₀ * e^(rt)
where N₀ is the initial population size, r is the growth rate parameter, and e is the mathematical constant approximately equal to 2.71828.
To find the time it takes for the population size to double, we can set N(t) equal to 2N₀ and solve for t:
2N₀ = N₀ * e^(rt)
Dividing both sides by N₀:
2 = e^(rt)
Taking the natural logarithm of both sides:
ln(2) = rt * ln(e)
Since ln(e) = 1:
ln(2) = rt
Solving for t:
t = ln(2)/r
Substituting the given growth rate parameter of 5.9% per hour:
t = ln(2)/(0.059) ≈ 11.72 hours
Therefore, it takes approximately 11.72 hours for the size of the population to double.

Students are making lemonade from a powdered lemon drink mix. Jonathan mixes 2 cups of water and 7 teaspoons of powdered lemon mix. Maya mixes 1 cup of water and 7 teaspoons of powdered lemon mix. Whose mix will be more lemony?
Group of answer choices
Maya’s mix will be more lemony.
Jonathan’s mix will be more lemony.
The two mixes will be equally lemony.
Answer: Maya’s mix will be more lemony.
Step-by-step explanation:
We see that both Jonathan and Maya mix 7 teaspoons of the powdered lemon mix. Since we are finding whose mix will be more lemony, we need to find the person who added less water since their mixture will be less diluted.
This leads us to Maya, she only added 1 cup of water while Jonathan added 2 cups of water. Maya's mixture will have a higher concentration since she has a higher ratio of lemon to water than Jonathan.

The fraction in factored form is determined as (x - 8)(x + 10) / (x - 10)(x + 8).
What is the quotient of the division?
The quotient of the division is calculated as follows;
( x² - 3x - 40 )/ (x² + 8x - 20) ÷ (x² + 13x + 40)/(x² + 12x + 20)
Factorize each of the expressions;
x² - 3x - 40
= x² + 5x - 8x - 40
= x(x + 5) - 8(x + 5)
= (x + 5)(x - 8)
x² + 8x - 20
= x² + 2x - 10x - 20
= x(x + 2) - 10(x + 2)
= (x + 2)(x - 10)
x² + 13x + 40
= x² + 5x + 8x + 40
= x(x + 5) + 8(x + 5)
= (x + 5)(x + 8)
x² + 12x + 20
= x² + 2x + 10x + 20
= x(x + 2) + 10(x + 2)
= (x + 2)(x + 10)
The fraction in factored form is written as;
(x + 5)(x - 8)/(x + 2)(x - 10) ÷ (x + 5)(x + 8)/(x + 2)(x + 10)
(x + 5)(x - 8)/(x + 2)(x - 10) x (x + 2)(x + 10)/(x + 5)(x + 8)

What is the value of y when x=5 and z=12?
Group of answer choices

Answer:
C
Step-by-step explanation:
y = k * z , where k is any constant
x=4, z=9 , y=360
360 = k (4)(9)
360 = 36 k
k = 360/36
k = 10
y = 10 * z

y = 10 (5)(12)

A researcher claims that adult males in the U.S. have gotten fatter since 1980, when they weighed 180.4 pounds on average. In 2023, you gather a sample of 10 males and which showed an average of 197.9 pounds. Assume o = 20 and a = .05.
As our determined t-score (2.77) is larger than the critical t-value (2.262), we disregard the null hypothesis in favor of the alternative one
How to solve
Given data:
The 1980 mean weight (μ) was 180.4 pounds, while the 2023 sample mean weight (x) was 197.9 pounds;
additionally, the sample size (n) was 10 and the sample standard deviation (σ) was 20 pounds.
At a significance level of 0.05, we calculate the t-score by first dividing (x-μ)/(σ/sqrt(n)).
This gives us the value 17.5/6.32 or 2.77 for the t-score.
Afterward, it is necessary to find the critical t-value with a two-tailed test at a significance level α=0.05 in respect to having 9 degrees of freedom (df = n – 1 = 10 – 1 = 9).
This can be located through either a t-distribution table or an online calculator; the result displays the calculated critical t-value being approximately ±2.262.
As our determined t-score (2.77) is larger than the critical t-value (2.262), we disregard the null hypothesis in favor of the alternative one, signifying there is a glaringly significant disparity between the average mass of grown male adults from 1980 and 2023 which upholds the researcher's statement that since 1980, males in the U.S. have gotten heavier.

Suppose you want to buy a car. The dealer offers a financing package consisting of a 4.6% APR compounded monthly for a term of five years. Suppose that you want your monthly payments to be at most $499. What is the maximum amount that you should finance? (Show your work using the formula and Round your answer to the nearest dollar.)
The maximum amount that you should finance is $26701 (rounded to the nearest dollar).
We can use the formula for monthly payments on a loan:
PMT = (PV x r x (1 + r)ⁿ) / ((1 + r)ⁿ - 1)
where PMT is the monthly payment, PV is the principal amount (the amount financed), r is the monthly interest rate, and n is the total number of months.
We can rearrange this formula to solve for PV:
PMT = (PV x r x (1 + r)ⁿ) / ((1 + r)ⁿ - 1)
Substituting the given values:
PMT = $499
r = 4.6% / 12 = 0.0038333 (monthly interest rate)
n = 5 x 12 = 60 (total number of months)
We get:
PV = $499 x ((1 + 0.0038333)⁶⁰- 1) / (0.0038333 x (1 + 0.0038333)⁶⁰)
PV = $26700.902
