Which figure represents the image of parallelogram
LMNP after a reflection across the line y = x?

o figure A
O figure B
o figure C
O figure D

Answers

The figure that represents the image of parallelogram LMNP after a reflection across the line y = x is figure C

How to determine the figure?

From the graph, the coordinates of the parallelogram LMNP are:

L = (3,1)

M = (4,3)

N = (5,3)

P = (4,1)

When reflected across the line y = x, the coordinates become

L' = (1,3)

M = (3,4)

N = (3, 5)

P = (1, 4)

The figure with the above coordinates is figure C

Hence, the figure that represents the image of parallelogram LMNP after a reflection across the line y = x is figure C

Eleanor Wotek took out a simple interest installment loan of $1,525 at 8 percent for 6 months. Her monthly payment on the loan is $260.17. After 3 payments, the balance is $769.98. If she pays off the loan when the next payment is due? a. What is the final payment? (2 points) b. How much is saved by paying off the loan early? (3 points)

Answers

Answer:

a. Final payment = $831.58

b. Amount saved = -$520.34

Step-by-step explanation:

a. What is the final payment? (2 points)

Interest element of fourth month payment = Principal balance after third month payment * 8% = $769.98 * 8% = $61.60

Final payment = Principal balance after third month payment + Interest element of fourth month payment = $769.98 + $61.60 = $831.58

b. How much is saved by paying off the loan early? (3 points)

Amount saved = (Monthly payment * 2 months) - Final payment = ($260.17 * 2) - $831.58 = -$520.34

Note:

The amount saved in part b above is negative i.e. -$520.34 which implies that Eleanor Wotek actually paid more instead of saving some amount.

So you can do 1/2 and then divide it by 1/8.

To divide by a fraction, multiply by its reciprocal.
So;
1/2 / 1/8 = 1/2•8/1

1/2• 8 = 8/2
8/2= 4

Father's shadow is 9 feet long.

Step-by-step explanation:

From the given figure,

ΔABC and PQR will be similar.

So their corresponding sides will be proportional.

[tex]\frac{AC}{PR}=\frac{BC}{QR}[/tex]

[tex]\frac{AC}{7.5}=\frac{6}{5}[/tex]

AC = [tex]\frac{6\times 7.5}{5}[/tex]

AC = 9 feet

Therefore, measure of the father's shadow is 9 feet.

can someone solve this please?

Answers

Answer:

3.16 units

Step-by-step explanation:

The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex].

Let,

[tex] (6, 8) = (x_1, y_1) [/tex]

[tex] (7, 5) = (x_2, y_2) [/tex]

Plug these values into the distance formula.

Thus:

[tex] d = \sqrt{(7 - 6)^2 + (5 - 8)^2} [/tex]

[tex] d = \sqrt{(1)^2 + (-3)^2} [/tex]

[tex] d = \sqrt{1 + 9} [/tex]

[tex] d = \sqrt{10} = [/tex]

d = 3.16 (nearest tenth)

Distance between the two points in the graph is approximately 3.16 units

Anna has a small business. Her mean revenue over the past 10 years is $85,000 with standard deviation of 2200. Anna earned 55% of her mean revenue by December 31, 2020. How much money does Anna want to have by year's end?

Answers

$121,000

Step-by-step explanation:

Mean = $85000

Standard deviation = $2200

55% of mean revenue at the end of the year will be :

0.55 * $2200

0.55 * 2200

= $121,000

Hence, Anna wants to have $121,000 by year end
