Answer:

Answer:

Let's take an example.

If you put the value of x as 1, it gives one.

Even if you put 3.997654, it will give 3.997654.

But for any negative real number, it gives the same number but not with it's negative sign. Like if x =-3/7,

It will give 3/7.

Which square root is between 4 and 5?
A. √ 10
B. √ 14
C. √24
D. √ 32

Answers

the answer would be D.
The answer is C.

To answer this, square both 4 and 5.

4^2 = 16
5^2 = 25

So the number you’re looking for under a square root needs to be between 16 and 25. 24 is the only number that fits the bill.

The answer is C.

Sophia used the Order of Operations to simplify 4(5 - 2) to 4x3.
Jose used the Distributive Property to simplify 4(5 - 2) to 20 - 8.
Are they both correct? Explain.

Answers

Answer:

Yes

Step-by-step explanation:

Order of operations, use the operation within the parenthesis:

1) 5 - 2 = 32) 4*3 = 12

Distributive property, a(b + c) = ab + ac:

1) 4*5 - 4*2 = 20 - 82) 20 - 8 = 12

Both ways are correct and lead to same result

which reflection carries parallelogram QRST onto itself?

Answers

Step-by-step explanation:

that 180° and 360° clockwise and counterclockwise rotations about this point will carry the parallelogram onto itself.

The parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.

What is the parallelogram?

A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel.

This means a parallelogram is a plane figure, a closed shape, and a quadrilateral.

If we rotate it in clockwise then it covers the angle [tex]180[/tex] degree and [tex]360[/tex] degree whether it is in clockwise or in anticlockwise.

Hence, the parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.

Mrs. Schellhaas spent $14.00 of the $20.00 she has on her Starbucks gift card. Which decimal represents the fraction of the $20.00 she spent

Answers

Answer:

0.7 or 70%

Step-by-step explanation:

Step 1 : Find what percent 14 is of 20. Set up an equation to solve for x.

14 = x (20)

Divide by 20 on both sides.

14 divided by 20 = 0.7

So the decimal which represents the fraction of the 20 bucks she spent is 0.7

Bonus step : If you want to find what is 0.7 in percentage form, then simply convert. 70/100 = 70 percent.

Step-by-step explanation:

Put the function arguments where they go and simplify in the usual way.

  f(g(x)) = f(√(5x³)) = 2(√(5x³))² +16 = 2(5x³) +16

  f(g(x)) = 10x³ +16

Answer: n = 0

Step-by-step explanation:

Given expression

(-3/4) (8n + 12) = 3 (n - 3)

Expand parentheses and apply the distributive property

-6n - 9 = 3n - 9

Add 9 on both sides

-6n - 9 + 9 = 3n - 9 + 9

-6n = 3n

Subtract 3n on both sides

-6n - 3n = 3n - 3n

-9n = 0

Divide -9 on both sides

Answers

The single payment would be $ 2,909.18.

Since loan payments of $ 1725 due today, $ 510 due in 75 days and $ 655 due in 323 days are to be combined into a single payment in 115 days, to determine what is the single payment if money is worth 8.5% and focal date is 115 days the following calculation must be made, offsetting the days in advance with the days in which the payment is late:  

8.5 / 365 x 115 = 2.6780 8.5 / 365 x (115 - 75) = 0.9315 8.5 / 365 x (115 - 323) = -4.8438 (1725 x 1.02678) + (510 x 1.009315) + (655 x (1 - 0.048438) = X 1,771.20 + 514.75 + 655 x 0.9515 = X 2,285.95 + 623.23 = X 2,909.18 = X

Therefore, the single payment would be $ 2,909.18.

Answer:

Step-by-step explanation:

since loan payments of $1725 due today. $510 due in 75 days and $655 due in 323 days are to be combined into single payment in 115 days.

now,

First, we need to calculate the present value of each payment using the given interest rate and the focal date of 115 days from now.

formula

The formula to calculate the single payment due 115 days from now is:

Single Payment = (PV1 / (1 + r1*(t1/365))) + (PV2 / (1 + r2*(t2/365))) + (PV3 / (1 + r3*(t3/365))) / (1 + r4*(t4/365))

Where:

- PV1, PV2, and PV3 are the present values of the three payments due today, in 75 days, and in 323 days, respectively.

- r1, r2, and r3 are the interest rates for each payment period.

- t1, t2, and t3 are the time periods in days between the payment due date and the focal date of 115 days from now.

- r4 is the interest rate for the period between the focal date and the payment due date of the single payment.

- t4 is the time period in days between the focal date and the payment due date of the single payment.

The present value of the payment due today is:

PV1 = 1725 / (1 + 0.085*(115/365)) = $1666.27

The present value of the payment due in 75 days is:

PV2 = 510 / (1 + 0.085*(75/365)) = $496.16

The present value of the payment due in 323 days is:

PV3 = 655 / (1 + 0.085*(323/365)) = $585.92

Next, we add up the present values of the three payments to get the total present value:

PV = PV1 + PV2 + PV3 = $2748.35

Finally, we calculate the single payment due 115 days from now by discounting the total present value to the focal date of 115 days from now:

Single Payment = PV / (1 + 0.085*(115/365)) = $2909.18

Therefore, the single payment due 115 days from now is $2909.18.
