Answers
Answer:
Line k
Step-by-step explanation:
The slope is found by rise/run which is change in y/change in x. If you look at a certain few points on line k, you will see it is 3/1 which is 3. The line is going downwards so it is -3.
Answer:
line k
Step-by-step explanation:
Hey There!
So immediately we notice that the slope is negative so we can eliminate line m and line n
So its between line k and j
we notice that it says -3
so the rise over run has to be down 3 over 1
line k shows exactly this
therefore line k is your answer :)

You invest $7000 in an account bearing 5% interest for ten years. A. How much will the account be worth if compounded quarterly? What about monthly? Daily? B. What do you notice about the amount of additional money you make as the frequency of compounding increases?
Answers
Answer:quarterly, monthly, daily
Step-by-step explanation:
quarterly: y=7000 (1+.05/4)'10(4) answer y=11,505.34
monthly: y=7000 (1+.05/12)'10(12) answer y=11,529.07
daily: y=7000 (1+.05/365)'10(365) answer y=11,540.65
What do you notice about the amount of additional money you make as the frequency of compounding increases? The account is worth more
The account will be worth approximately $11,505 if compounded quarterly.
The account will also be worth approximately $11,540 if compounded daily.
A. Compounded quarterly:
n = 4 (quarterly compounding)
A = 7000(1 + 0.05/4[tex])^{(4)(10)[/tex]
A ≈ 7000(1.0125)⁴⁰
A ≈ 7000 x 1.643619463
A ≈ 11505.34
The account will be worth approximately $11,505 if compounded quarterly.
B. Compounded monthly:
n = 12 (monthly compounding)
A = 7000(1 + 0.05/12[tex])^{(12)(10)[/tex]
A ≈ 7000(1.00416666667)^(120)
A ≈ 7000 x 1.6487212707
A ≈ 11540.05
The account will be worth approximately $11,540 if compounded monthly.
C. Compounded daily:
n = 365 (daily compounding)
A = 7000(1 + 0.05/365)^(365*10)
A ≈ 7000(1.0001369863)^(3650)
A ≈ 7000 * 1.6487212707
A ≈ 11540.05
The account will also be worth approximately $11,540 if compounded daily.
B. As the frequency of compounding increases, the additional money earned (compared to simple interest) becomes more significant. In this case, regardless of whether the interest is compounded quarterly, monthly, or daily, the resulting values are very close to each other.

Solve the following inequality for y.
18x + 6y > 12
Answers
Answer:
12
Step-by-step explanation:
Simplifying
18x + -6y = 12
Solving
18x + -6y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
18x + -6y + 6y = 12 + 6y
Combine like terms: -6y + 6y = 0
18x + 0 = 12 + 6y
18x = 12 + 6y
Divide each side by '18'.
x = 0.6666666667 + 0.3333333333y
Simplifying
x = 0.6666666667 + 0.3333333333y

Answer:

Step-by-step explanation:
Using the cosine ratio and the exact value
cos45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{n}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2BC = n[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
BC = [tex]\frac{n\sqrt{2} }{2}[/tex] → D

Find the length of a side of a square if its area is 4/25 cm^2. *
Answers
Answer:
The length of a side of the square will b 2/5 cm.
Step-by-step explanation:
To find the area of a 2d object, you need to multiply length and width together. Since it's a square, all the sides are the same length, so that makes it easier. We need to find the square root of 4 and 25. [tex]\sqrt{4}[/tex] is 2, and [tex]\sqrt{25}[/tex] is 5.
Now we need to multiply 2/5 by itself to check. 2/5 x 2/5 = 0.16, or 4/25. The answer is correct. The final result is 2/5. Hope this helped!! :]
The area of a square is the square of one of its side lengths. The length of a side of the square is 2/5 cm
Given:
[tex]Area = \frac{4}{25}cm^2[/tex]
Shape: Square
The area of a square is:
[tex]Area = Length^2[/tex]
So, we have:
[tex]Length^2 = \frac 4{25}cm^2[/tex]
Take positive square roots of both sides
[tex]Length = \sqrt{\frac 4{25}cm^2}[/tex]
[tex]Length = \frac 2{5}cm[/tex]
Hence, the length of the square where the area is [tex]\frac 4{25}cm^2[/tex] is [tex]\frac 2{5}cm[/tex]

Mango mixed 24 ounces of blue paint with 16 ounces of red paint to create a new purple color. In order to create 72 more ounces of this exact purple color, how many ounces of red paint would she need
Answers
Answer: 28.8 ounces of red paint
Step-by-step explanation:
The total amount of paint created the first time Mango mixed colors was:
= 24 + 16
= 40 ounces of purple color
For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:
= 16/40
If one wants 72 ounces of purple therefore:
= Proportion of red used * 72 ounces
= 16/40 * 72
= 28.8 ounces of red paint
