Answer 1

Answer:

The answer is B. Hope this helps!

Step-by-step explanation:

105 degrees is from a b to d and a b to c is 75 and 105 - 75 =30.

Answer 2

Answer:

30*

Step-by-step explanation:

If ABD is 105* then it would be <ABC+<CBD=105*. We know that <ABC is 75* so we can fill that in. 75*+<CBD=105*. Then we solve.

75* + <CBD = 105*

-75*                  -75*

<CBD=30*

So that's how I got it.

The asterisks are the degree signs.

Please help

Answers

Answer:

Step-by-step explanation:

From the picture attached,

9). When pre-image KLMN is a reflected across x = -2, we get image K'L'M'N'.

    Therefore, line of reflection will be x = -2

10). In this picture line of reflection which passes through origin (0, 0) and slope = 1 will be,

y = x.

11). Since, all the points of image and preimage points are equidistant from x-axis, line of reflection will be x-axis or y = 0.

12). Line passing through midpoint of the line joining BB' will be the line of reflection.

Coordinates of B → (5, 3)

Coordinates of B' → (5, 7)

Coordinates of BB' → [tex](\frac{5+5}{2},\frac{3+7}{2})[/tex] → (5, 5)

Therefore, line of reflection will be y = 5.

13). Coordinates of G → (2, 5)

     Coordinates of G' → (-2, 5)

     Midpoint joining the segment GG' → [tex](\frac{2-2}{2},\frac{5+5}{2})[/tex] → (0, 5)

     Therefore, line of reflection → x = 0

14). Line of reflection passing through (0, 0) and slope = -1

     y = -x

Which one is the right answer?

Answers

Answer:

D

Step-by-step explanation:

First of all, i mean A and B are out first thing because you don't have enough information to find out if it's true.

C is incorrect because as stated before, not enough information.

However,

You know that the angles 1-8 are all supplementary, which means that 1 and 2 can be added to make 180 degrees, as so can 3 and 4, 3 and 1. 2 and 4, blah blah blah.

In D, the angles that are being added are supplementary, because the three lines making up that weird figure is adjacent and is parallel to each other.

If you give one of the angles a degree, you know that 180-x with x being that degree, will equal the other angle on the other side of the lines.

Therefore its D.

Edit:

I just realized that theres an angle stated at the top of the screen. Still with that angle given, A and B is incorrect and the answer is still D.

Grayson is behind on his retirement savings and wants to start saving $1,000 per month so he can retire in 20 years. If he earns 9% a year, compounded monthly, how much money will Grayson have to retire? $622,447 $667,887 $684,254 $724,333

Answers

If Grayson begins saving $1,000 per month and makes 9% a year, compounded monthly, he will have $667,887 in retirement. Therefore, $667,887 is the correct number.

Future Value: What Is It?

A financial notion known as future value (FV) gives a worth to an asset based on anticipated factors like future interest rates and cashflows. Knowing how much their money might be in five years, given an anticipated rate of return, may be helpful for an investor. Future value is the idea of taking the investment's current worth, adding anticipated development, and estimating what the investment is going to cost in the future.

To calculate the amount of money Grayson will have at retirement, we can use the formula for the future value of an annuity:

FV = Pmt x (((1 + r/n)^(n*t)) - 1) / (r/n)

where:

FV is the future value of the annuity (i.e., the amount Grayson will have at retirement)

Pmt is the monthly payment ($1,000 in this case)

r is the annual interest rate (9% in this case)

The number of annual increasing times is n. (12 for monthly compounding)

t is the number of years (20 in this case)

Plugging in the numbers, we get:

FV = 1000 x (((1 + 0.09/12)⁽¹²*²⁰⁾) - 1) / (0.09/12)

FV = $667,887.20

Therefore, Grayson will have $667,887 at retirement if he starts saving $1,000 per month and earns 9% a year, compounded monthly. Therefore, the answer is $667,887.

Solving steps for x:

Select all the sequences of reflections that produce an image equivalent to the image r(180°, O)(△BCD).

Answers

Answer:

r(180°,0) is a rotation of 180° degrees over the origin.

Notice that this rotation moves our figure to the opposite quadrant (so a translation of two quadrants).

Then this is equivalent to:

A reflection over the x-axis followed by a reflection over the y-axis.

Or.

A reflection over the y-axis followed by a reflection over the x-axis.

There is another possible reflection, but it depends on where is our figure.

If the figure is in the first or third quadrant, a reflection over the line y = -x is equivalent to the rotation.

If the figure is in the second or third quadrant, then the reflection over the line y = x is equivalent to the rotation.

We can combine those two and write:

A reflection over the line y = (-1)^n*x.

Where n is the number associated with the quadrant where the figure is in.

Step-by-step explanation:

7 ( 7 + 5r ) = 7 ( 7 + 6r )

First use the ditributive property of multiplication -

49 + 35r = 49 + 42r

Subtract 35r from both sides -
