Your friends, Fernando and Amelia, each own a video game designer company. They both want you to join their company. You currently have a part-time job making $8. 00 per hour. Fernando offers to pay you $15 per hour for the first month and then increase your hourly rate by $1. 00 each month. Amelia says she will start your pay at $8. 00 per hour but she will increase your hourly rate by 10% each month. In order to make the best decision, you decide to use the mathematics to choose the best offer based on the best hourly wage per month.
Write the equations to represent Fernando’s job offer and Amelia’s job offer. Let x = number of months, y = hourly wage.
Under what time period would you accept Fernando’s offer? Use mathematics to support your reasoning.
Under what time period would you prefer Amelia’s offer? Use mathematics to support your reasoning.
Now that we have looked at the different figures for Fernando and Amelia, which job would you take for the long run? Use mathematics to justify your answer
Answers
Answer:
The equation to represent Fernando's job offer is:
y = 15 + x
Where y is the hourly wage and x is the number of months worked.
The equation to represent Amelia's job offer is:
y = 8(1 + 0.1)^x
Where y is the hourly wage and x is the number of months worked.
To determine the time period for which Fernando's offer is better, we need to find the point where his hourly wage is greater than Amelia's. We can set the two equations equal to each other and solve for x:
15 + x = 8(1 + 0.1)^x
15 + x = 8(1.1)^x
x ≈ 20.44
Therefore, Fernando's offer is better for any time period greater than 20.44 months.
To determine the time period for which Amelia's offer is better, we need to find the point where her hourly wage is greater than Fernando's. We can set the two equations equal to each other and solve for x:
8(1 + 0.1)^x = 15 + x
8(1.1)^x = 15 + x
x ≈ 14.45
Therefore, Amelia's offer is better for any time period less than 14.45 months.
For the long run, we need to determine which offer has a higher hourly wage after a certain number of months. We can compare the two equations by finding their limits as x approaches infinity:
lim (y = 15 + x) as x → ∞ = ∞
lim (y = 8(1 + 0.1)^x) as x → ∞ = ∞
Therefore, both offers have the same long-term hourly wage of infinity. However, Fernando's offer has a faster rate of increase, so it may be more beneficial in the long run.

If left to leak at this rate indefinitely, will the tank empty all of its contents as a result of this crack?
Answers
If left to leak at this rate indefinitely, the tank will not empty all of its contents as a result of this crack, as it would take approximately 853.33 days for the tank to reach zero capacity
To determine whether the tank will empty all of its contents as a result of the crack,
we need to find out how long it will take for the tank to reach zero capacity.
Using the given model, the rate at which the contents spill out over time is 200 - 0.075t,
where t is the number of days since the leak began on October 10th, 2021.
We can set up an equation to find out when the tank will reach zero capacity:
5000 - (200 - 0.075t) = 0
Simplifying this equation, we get:
0.075t = 4800
t = 64000/75
t = 853.33
Therefore, if left to leak at this rate indefinitely, the tank will not empty all of its contents as a result of this crack, as it would take approximately 853.33 days for the tank to reach zero capacity.

Write a function to model the cost C after t years since 2000.
If the trend continues, how much would a student expect to pay for room and board in 2017? Express your answer as a decimal rounded to the nearest hundredth.
Answers
A student would expect to pay approximately $7,096.47 for room and board in 2017. Rounded to the nearest hundredth, this is $7,096.47 rounded to $7,096.50.
What is Function ?
In mathematics, a function is a rule that assigns each element in a set (the domain) to a unique element in another set (the range). The domain and range can be any sets, but they are typically sets of real numbers.
The cost of room and board after t years since 2000 can be modeled by the equation:
C(t) = 4291[tex](1 + 0.031)^{t}[/tex]
where C(t) is the cost after t years.
To find out how much a student would expect to pay in 2017, we need to plug in t = 17 (since 2017 is 17 years after 2000) into the equation:
C(17) = 4291[tex](1 + 0.031)^{17}[/tex]
≈ 7,096.47
Therefore, a student would expect to pay approximately $7,096.47 for room and board in 2017. Rounded to the nearest hundredth, this is $7,096.47 rounded to $7,096.50.

Next Problem (1 point) Suppose f"(x) = -(sin(x)), f'(0) = 0, and f(0) = -3. - Find f(1/4). f(1/4) = 1
Answers
f(1/4) is approximately equal to -2.9974. The problem states that f"(x) = -(sin(x)), which means that the second derivative of the function f(x) is equal to the negative of the sine of x. We are also given that f'(0) = 0 and f(0) = -3.
To find f(1/4), we need to use the information given to us and apply the process of integration. We know that the first derivative of f(x) is f'(x), so we need to integrate f"(x) to find f'(x). Integrating the negative sine function will give us the cosine function, so:
f'(x) = -cos(x) + C
Where C is a constant of integration. To find the value of C, we use the fact that f'(0) = 0:
0 = -cos(0) + C
C = 1
So now we have:
f'(x) = -cos(x) + 1
Next, we integrate f'(x) to find f(x):
f(x) = -sin(x) + x + D
Where D is another constant of integration. We can find the value of D by using the fact that f(0) = -3:
-3 = -sin(0) + 0 + D
D = -3
So finally, we have:
f(x) = -sin(x) + x - 3
Now we can find f(1/4):
f(1/4) = -sin(1/4) + (1/4) - 3
f(1/4) = -0.2474 + 0.25 - 3
f(1/4) = -2.9974
Therefore, f(1/4) is approximately equal to -2.9974.

The mean test score of 12 students is 42. A student joins the class and the mean becomes 43. Find the test score of the student who joined the class
Answers
The test score of the student who joined the class is 55.
To find the test score of the student who joined the class, we can use the formula for calculating the mean:
Mean = (Sum of all values) / (Number of values)
We know that the mean test score of the original 12 students was 42. This means that the sum of their test scores was:
Sum of scores = Mean x Number of students = 42 x 12 = 504
Now, when the new student joins the class, the mean test score becomes 43. This means that the sum of all 13 students' test scores is:
Sum of scores = Mean x Number of students = 43 x 13 = 559
We can subtract the sum of the original 12 students' test scores from the sum of all 13 students' test scores to find the test score of the student who joined the class:
Test score of new student = Sum of all scores - Sum of original scores
Test score of new student = 559 - 504
Test score of new student = 55
Therefore, the test score of the student who joined the class is 55.

Determine an equation for an exponential that model this data set in form p=a(b)^t justify both your values of a and b round b to the nearest hundredth
Answers
The equation for an exponential that models this data set is: p = 10(2)^t
To determine an equation for an exponential that models the given data set in the form p = a(b)^t, we first need to identify the values of a and b. To do this, we can use two points from the data set and solve for a and b. Let's choose the points (0, 10) and (2, 40):
When t = 0, p = 10: 10 = a(b)^0 = a
When t = 2, p = 40: 40 = a(b)²
Dividing the second equation by the first, we get:
4 = (b)²
Taking the square root of both sides, we get:
b = 2
Now that we have the value of b, we can use one of the original equations to solve for a:
10 = a(2)^0 = a
So, a = 10.
Therefore, the equation for an exponential that models this data set is:
p = 10(2)^t
We can check this equation by plugging in the other data points and verifying that they satisfy the equation. And rounding b to the nearest hundredth gives us b = 2.00.

C. 33%
D. 75%
Answers
The closest answer is C. 33%.
We can use the percent decrease formula to calculate Sara's percent decrease in the time it takes her to run a mile:
percent decrease = [(original value - new value) / original value] x 100%
In this case, Sara's original time was 12 minutes and her new time is 8 minutes, so we have:
percent decrease = [(12 - 8) / 12] x 100%
percent decrease = (4 / 12) x 100%

In two or more complete sentences, describe the transformation(s) that take place on the parent function F=f(x)=log(x) to achieve the graph of g(x)=log(-3x-6)-2
Answers
The transformations that take place on the parent function F=f(x)=log(x) to achieve the graph of g(x)=log(-3x-6)-2 are horizontal compression and vertical shift.
What transformations took place in the function?The transformations are a horizontal compression and a vertical shift.
Horizontal compression: The factor of 3 in the argument of the logarithm function causes a horizontal compression by a factor of 1/3. This means that the graph of g(x) is narrower than the graph of f(x) and it is shifted to the left.Vertical shift: The constant term of -2 is subtracted from the logarithm function, causing a vertical shift downwards by 2 units.Therefore, the transformations can be expressed mathematically as follows:
g(x) = log(-3x - 6) - 2
= log(-3(x + 2)) - 2
= log(1/3)log(-3(x + 2)) - 2
Therefore, the transformations are a horizontal compression by a factor of 1/3 and a vertical shift downwards by 2 units.

To find dy/dx implicitly, we need to differentiate both sides of the equation with respect to x, treating y as a function of x and using the chain rule.
In this problem, we are given the equation X^2e^{-x} + 3y^2 - xy = 0, and we need to find dy/dx. To do this, we first differentiate each term with respect to x, using the product rule for the xy term and the chain rule for the y^2 term. Then we can solve for dy/dx by isolating the derivative term on one side of the equation. Implicit differentiation is a powerful technique used in calculus to find derivatives of functions that are not easily expressed in terms of a single variable.

The sales tax is 8.25% of the total cost of the shirt and shoes, so we need to add this to the cost of the items:
Cost of shirt = $15.75
Cost of shoes = $10.25
Total cost before tax = $15.75 + $10.25 = $26.00
Sales tax = 8.25% of $26.00 = 0.0825 x $26.00 = $2.15

The correlation coefficient only tells us the strength and direction of the relationship; it does not tell us anything about the proportion of variation in one variable that is explained by the variation in the other variable.
The determination coefficient (r²), also known as the coefficient of determination, is a measure of the proportion of variation in one variable that is explained by the variation in the other variable. It ranges from 0 to 1, with 0 indicating that none of the variation in one variable is explained by the variation in the other variable, and 1 indicating that all of the variation in one variable is explained by the variation in the other variable. The determination coefficient is calculated as the square of the correlation coefficient, so r² always has the same sign as r. A value of r² close to 1 indicates that the relationship between the variables is strong and that a large proportion of the variation in one variable can be explained by the variation in the other variable.
In summary, the correlation coefficient tells us about the strength and direction of the linear relationship between two variables, while the determination coefficient tells us about the proportion of variation in one variable that is explained by the variation in the other variable.
While correlation coefficient measures the strength and direction of the relationship between two variables, determination coefficient measures how much of the variability in one variable can be explained by the other variable.
The correlation coefficient and determination coefficient are two related statistical measures that help us understand the strength and direction of a relationship between two variables. The correlation coefficient (denoted as r) measures the strength and direction of a linear relationship between two variables. It ranges from -1 to 1, with -1 indicating a strong negative relationship, 1 indicating a strong positive relationship, and 0 suggesting no relationship.
On the other hand, the determination coefficient (represented as R²) quantifies the proportion of variance in the dependent variable that is predictable from the independent variable. It ranges from 0 to 1, with 0 indicating no explanatory power and 1 indicating perfect prediction. R² is simply the square of the correlation coefficient (r²).
In summary, while the correlation coefficient shows the strength and direction of a linear relationship, the determination coefficient indicates the extent to which one variable can predict the other. Both are important in determining the nature of relationships between variables in a data set.

The quadratic equation given the points (6,0), (-1,0), and (7,4).
The correct answer is h(x) = 1/2(x + 1)(x - 6).
To find the quadratic equation given the points (6,0), (-1,0), and (7,4), we can use the general form of a quadratic equation, which is [tex]h(x) = ax^2 + bx + c.[/tex]
First, let's substitute the coordinates of the given points into the equation to create a system of equations:
For the point (6,0):
[tex]0 = a(6)^2 + b(6) + c ---- (1)[/tex]
For the point (-1,0):
[tex]0 = a(-1)^2 + b(-1) + c ---- (2)[/tex]
For the point (7,4):
[tex]4 = a(7)^2 + b(7) + c ---- (3)[/tex]
We now have a system of three equations with three unknowns (a, b, c). We can solve this system to find the values of a, b, and c.
Solving the system of equations (1), (2), and (3), we find:
a = 1/2
b = -3/2
c = 0
Thus, the quadratic equation that satisfies the given points is:
h(x) = 1/2(x + 1)(x - 6).

A) we can forecast that 15,007 will attend this year's county fair.
B) we can expect approximately 1,001 people to receive a prize.
How did we get the above conclusions?Using the attendance data given, we can find the %increase in attendance from year to year as follows
From year 1 to year 2 - (10,365 - 9,278)/9,278
≈ 0.117 or 11.7%
From year 2 to year 3 - (12,128 - 10,365)/10,365
≈ 0.170 or 17.0%
From year 3 to year 4 - (13,304 - 12,128)/12,128
≈ 0.097 or 9.7%
finding the average of the tree percentages, we have
(11.7% + 17.0% + 9.7%)/3 ≈ 12.8 %
So applying this to the last years attenance we have:
1.129 x 13,304 = 15020.216
Or 15,020 since people cannot be in decimal format.
2)
Since the first 20% of people attending the fair will receive a raffle ticket, we can estimate the number of raffle tickets as follows ....
15,007 ×0.20 = 3, 001.4
Now we can estimate the number of people who will receive a prize by taking one-third of the number of raffle tickets...
3,002 ÷ 3 ≈1 ,000.7
which is approximatly 1001 people.
