If you invested $4,500 for 8 months at an interest rate of 2.75%, how much interest would you earn?
Given the money invested and the interest rate, the value of the interest earned after 8 months is $82.50.
What is the value of the Interest?
From the equation of simple interest; I = PRT
Given that;
Principal P = $4,500Interest rate R = 2.75% = 2.75/100 = 0.0275Time T = 8 months = 8/12 yearsInterest I = ?I = PRT
I = $4,500 × 0.0275 × 8/12
I = $82.50
Given the money invested and the interest rate, the value of the interest earned after 8 months is $82.50.

Mr. Carson washes his car every 8 days, checks the oil every 7
days, and checks the tire pressure every 9 days. He washed it Monday July 18,
2022, checked the oil on Wednesday and checked the tire pressure on Thursday
of that same week. When is the first day after that Monday on which he will
do all these activities on the same day? Find the number of days counted from
that Monday July 18, 2022.
The first day when he would do these activities on the same day is December 7, 2023.
When would he do these activities on the same day?In order to determine which day Mr. Carson would wash his car, check his oils and check the tire pressure, the multiple of 8, 7, and 9 have to be determined.
A multiple of a number is the product of an integer and that number. A common multiple is a number that is common to all three numbers. The lowest common multiple of 8, 7 and 9 is 504. So, in 504 days he would do all three activities on the same day.
In order to convert 504 days, take note of the following:
365 days = 1 year
12 month = 1 year
1 month = 4 weeks
30 days = 1 month
504 / 365 = 1 year 139 days
139 days / 30 days = 4 months 19 days
504 days = 1 year, 4 months and 19 days

if the graph of f(x)=x^2 how will the graph be affected if the coefficient of x^2 is change to 1/3
The graph would be affected by horizontally stretching the curve of f(x) = x^2 when the coefficient is changed
How to determine the change?The function is given as:
f(x) = x^2
When the coefficient of x^2 changes to 1/3, we have:
f(x) = 1/3x^2
The above represents a stretch of the function
This means that the graph would be affected by horizontally stretching the curve of f(x) = x^2 when the coefficient is changed

What is the equation of g(x)?
Og(x) = 5x-9
Og(x) = 5x-10
Og(x) = 5-9
Og(x) = 5-10
g(x) is just a translation of 10 units downwards, this means that the equation for g(x) is:
[tex]g(x) = f(x) - 10 = 5^x - 10[/tex]
Which is the equation of the translation?Here we know that:
[tex]f(x) = 5^x[/tex]
And we want to find the equation for g(x), which is a translation of f(x).
If you look at the graph of f(x), you can see that it passes through:
(0, 1), (1, 5), (2, 25), etc.
And the graph of g(x) passes through:
(0, -9), (1, -5), (2, 15)
So in each point, the y-component is 10 units smaller than the correspondent for f(x).
Then g(x) is just a translation of 10 units downwards, this means that the equation for g(x) is:
[tex]g(x) = f(x) - 10 = 5^x - 10[/tex]
So the correct option is the last one.

Slope-Intercept Form
Answer:
y = x - 2
Step-by-step explanation:
The general structure of an equation in slope-intercept form is:
y = mx + b
In this formula, "m" represents the slope and "b" represents the y-intercept. Before writing our equation in this form, we first need to find the slope. The slope can be found using the point-slope formula:
y₁ - y₂ = m(x₁ - x₂)
In this formula, "m" represents the slope, "x₁" and "y₁" represent the values from Point One, and "x₂" and "y₂" represent the values from Point Two. You can find the slope by plugging the values from the points into the equation and then simplifying.
x₁ = 0 x₂ = -3
y₁ = -2 y₂ = -5
y₁ - y₂ = m(x₁ - x₂)
(-5 - (-2)) = m(-3 - 0)
-3 = m(-3)
1 = m
Now that we have a value for the slope, we can use the values from either one of the points to solve for the y-intercept (from the slope-intercept form equation).
m = 1
x = 0
y = -2
y = mx + b
-2 = (1)(0) + b
-2 = 0 + b
-2 = b
Therefore, the equation of the line in slope-intercept form is:
y = x - 2

Hello!
Since both equations are equal to y, we can set the right-hand side of the equations equal to each other.
[tex]y = 2x + 3\\y = x^2 + 3x + 3[/tex][tex]y = y[/tex][tex]2x + 3 = x^2 + 3x + 3[/tex]Solve for x[tex]2x + 3 = x^2 + 3x + 3[/tex][tex]0 = x^2 + x[/tex][tex]0 = x(x + 1)[/tex][tex]x = 0, x =-1[/tex]X can either be 0 or -1. Remember, a solution to a system is not complete without a y-value. Plug in 0 and -1 for x in the first equation, and find the corresponding y-values.
[tex]y = 2(0) + 3\\y = 3[/tex]
And
[tex]y = 2(-1) + 3\\y = -2 + 3\\y = 1[/tex]
So the solutions to the system are (0,3) and (-1,1)

Party trays which cost $14 to make not including labor are sold for $35 if two people work eight hour shifts making the tray at seven dollars per hour how many trays must be sold to cover the cost including the labor?
Approximately 5 number of trays must be sold to cover all costs including labor.
How to find the work proportion?The profit on each tray that was sold excluding labor cost is;
Profit = $35-$14
Profit = $21
Total labor cost for making party tray for a day is;
Total Labor Cost = Total labor hours * wages per hour * No. of labors
Total Labor cost = $7 * $8*2
Total Labor Cost = $112
Number of trays that must be sold to cover cost is;
Total labor cost/ Profit per tray
Number of trays = $112/$21

Select the graph that best represents the inequality above.
Answer: B
Step-by-step explanation: Since x is less than 7, the graph would be all real numbers that are less than 7, so the arrow would be on the left.
Also, since x is not 7 itself (not less than or equal to), the dot cannot be a full dot. Thus, the dot must be open (or curved in some textbooks) to indicate x is not apart of 7 but less than 7.

What is a limit?A limit is given by the value of function f(x) as x tends to a value.
In this problem, to find the polynomial, we have to find the limits as x goes to infinity, hence:
[tex]\lim_{x \rightarrow -\infty} f(x) = [tex]\lim_{x \rightarrow -\infty} -a x^n[/tex]
