When x is 3, the purple line's y-value is between 4 and 6, which is 5.
Answer:
B
Step-by-step explanation:
You have two black lines with the arrows at the end. The one going left and right is your X-Axis. The one going up and down is the Y-Axis.
What they want to know is what is f(x) when x = 3
f(x) is another term for y
So they want to know, what is the value of the y-axis when x is 3 on the x-axis.
So on the line going left and right you find the line 3, between 2 and 4, then going up until you hit the purple line. Once you hit the purple line, go left until you hit the up and down line. That will give you an answer of 5

A recipe calls for cup
of chopped walnuts. You chop 4 walnuts
and get of the amount you need.
-
4
How much more of a cup of chopped
walnuts do you need? All your walnuts
are the same size. How many more
walnuts should you chop? Explain.
If you already chopped 4 walnuts and you have only gotten 1/4 cup of the chopped walnuts, it means that each walnut yields 1/4 cup / 4 walnuts = 1/16 cup of chopped walnuts.
To find out how much more chopped walnuts you need, we can subtract the amount you have from the total amount the recipe calls for:
1 cup - 1/4 cup = 3/4 cup
So you need 3/4 cup of chopped walnuts more.
To find out how many more walnuts you should chop, divide the amount you need by the amount each walnut yields:
3/4 cup / (1/16 cup/walnut) = 12 walnuts
So you should chop 12 more walnuts to get the desired amount.
the perimeter of a playing field for a certain sport is 308 ft the field is a rectangle and the length is 44ft longer than the width. find the dimensions
The dimensions of the playing field are a length is 99 ft, and a width is 55 ft.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
Given that the length is 44ft longer than the width.
This means L = W + 44 ....(i)
Since the perimeter of a playing field is 308 ft
So 2(L+W) = 308
Substitute the value of the equation (i), and we get
2(W + 44 + W) = 308
2(2W + 44) = 308
4W + 88 = 308
4W = 220
W = 55
Substitute the value of W = 55 in equation (i), and we get
L = 55 + 44 = 99
Thus, the length is 99 ft, and the width is 55 ft.

With only a part-time job and the need for a
professional wardrobe, Rachel quickly
maxed out her credit card the summer after
graduation.
With her first full-time paycheck in August,
she vowed to pay $320 each month toward
paying down her $8,975 outstanding
balance and not to use the card.
The card has an annual interest rate of 17%.
How long will it take Rachel to pay for her
wardrobe? Should she shop for a new card?
Why or why not?
It will take Rachel 5 months to pay off her debt at her current monthly payment rate.
What do you mean by Interest rate?Interest rate is a percentage that represents the amount of interest charged by a lender to a borrower for the use of money. It is used to calculate the interest that will accrue on a loan or deposit over a specific period of time, and is usually expressed as an annual rate. It is a key component in determining the cost of borrowing money, and affects the amount that must be paid back to the lender, including the principal amount and any additional interest charges.
Rachel's monthly payment of $320 will only cover the interest on her debt and will not significantly reduce the outstanding balance. She would need to pay more each month or find a way to reduce the interest rate in order to pay off her debt in a reasonable amount of time.
To calculate the time it will take for Rachel to pay off her debt, we can use the following formula:
n = ceil(log(P/A) / log(1 + r))
where n is the number of payments, P is the initial balance, A is the monthly payment, and r is the monthly interest rate (expressed as a decimal).
In this case, P = $8,975, A = $320, and r = 17% / 12 = 0.17 / 12 = 0.01417.
So, n = ceil(log($8975 / $320) / log(1 + 0.01417)) = ceil(log(28.09375) / log(1.01417)) = ceil(4.3626) = 5.
It will take Rachel 5 months to pay off her debt at her current monthly payment rate. This means that it will take her just over 4 years to pay off the debt, assuming no additional purchases are made on the card and the interest rate does not change.
As for shopping for a new card, Rachel should consider a card with a lower interest rate. This will allow her to pay off her debt more quickly and save money in interest charges. She may also consider a balance transfer card with an introductory 0% interest rate, which would give her time to pay off the debt without accruing interest. However, she should be aware of any balance transfer fees that may apply. It is best for Rachel to compare options and read the fine print before making a decision.

You want to buy a $204,000 home. You plan to pay 10% as a down payment, and take out a 30 year loan for the rest.
The monthly mortgage payment for a $204,000 home with a 10% down payment and a 30 year loan at an interest rate of 3.5% would be approximately $808.44.
Solution
To calculate the monthly mortgage payment for a $204,000 home with a 10% down payment and a 30 year loan.
We'll need to first calculate the amount of the loan and then use the following formula to calculate the monthly payment:
M = P * r * (1 + r)^n / ((1 + r)^n - 1)
where M is the monthly payment P is the principal (loan amount) r is the monthly interest rate n is the number of paymentsFirst, we'll calculate the down payment:
Down payment = 204,000 * 0.10 = $20,400
Next, we'll calculate the loan amount:
Loan amount = 204,000 - 20,400 = $183,600
Now, we'll need to convert the 30 year loan term into the number of payments (n) and the interest rate into the monthly interest rate (r):
n = 30 years * 12 months/year = 360 payments
r = (Annual interest rate) / 12 months/year
Assuming an annual interest rate of 3.5%, the monthly interest rate would be:
r = 0.035 / 12 = 0.002917
Finally, we can plug the values into the formula to calculate the monthly mortgage payment:
M = 183,600 * 0.002917 * (1 + 0.002917)^360 / ((1 + 0.002917)^360 - 1) = $808.44
Therefore, the monthly mortgage payment for a $204,000 home with a 10% down payment and a 30 year loan at an interest rate of 3.5% would be approximately $808.44.

Show that x-3 and x+5 are factors of x^4+2x^3-16x^2-2x+15. Explain your reasoning using long division, Synthetic Division and Remainder theorem.
Answer:
Step-by-step explanation:
To show that x-3 and x+5 are factors of x^4+2x^3-16x^2-2x+15, we can use polynomial division, synthetic division, and the Remainder theorem.
Using long division, we can divide x^4+2x^3-16x^2-2x+15 by x-3:
x^4 + 2x^3 - 16x^2 - 2x + 15
÷ x - 3
_________________________
x^3 + 5x^2 - 14x - 12
|__________
-3x^3 + 17x^2 + 26x + 36
|_________
-14x^2 - 23x - 36
|_________
-15x + 72
|___
57
So, the remainder is 57, which means x^4 + 2x^3 - 16x^2 - 2x + 15 = (x - 3)(x^3 + 5x^2 - 14x - 12) + 57.
Using synthetic division, we can divide x^4 + 2x^3 - 16x^2 - 2x + 15 by x+5:
1 2 -16 -2 15
x + 5 |x^4 + 2x^3 - 16x^2 - 2x + 15|
____________________________
x^3 - 3x^2 + 21x + 75
So, the remainder is 0, which means x^4 + 2x^3 - 16x^2 - 2x + 15 = (x + 5)(x^3 - 3x^2 + 21x + 75).
Using the Remainder theorem, we know that if a polynomial p(x) is divided by x-a, the remainder is p(a). So, when we plug in x=3, the remainder should be p(3) = 57. When we plug in x=-5, the remainder should be p(-5) = 0. This confirms that x-3 and x+5 are indeed factors of x^4 + 2x^3 - 16x^2 - 2x + 15.

In ΔJKL, j = 1.7 inches, m m∠J=120° and m m∠K=47°. Find the length of k, to the nearest 10th of an inch.
Answer: We can use the Law of Cosines to find the length of side k in ΔJKL:
k^2 = j^2 + l^2 - 2 * j * l * cos(m∠K)
k = √(j^2 + l^2 - 2 * j * l * cos(m∠K))
Substituting the given values, we get:
k = √(1.7^2 + l^2 - 2 * 1.7 * l * cos(47°))
k = √(2.89 + l^2 - 2.94 * l * cos(47°))
To the nearest 10th of an inch, k = √(2.89 + l^2 - 2.94 * l * cos(47°)) = 3.3 inches.
