Answer:

[tex]B =(3.3,1.7)[/tex]

Step-by-step explanation:

Given

[tex]A(x_1,y_1) = (-4,-2)[/tex]

[tex]P(x,y) = (2,1)[/tex]

[tex]m : n = 9 : 2[/tex]

Required

The coordinates of [tex]B(x_2,y_2)[/tex]

The line segment from ratio is calculated as:

[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]

Substitute: A, P, m and n

[tex](2,1) = (\frac{9 * x_2 + 2*-4}{9+2},\frac{9*y_2 +2 *-2}{9+2})[/tex]

[tex](2,1) = (\frac{9x_2 -8}{11},\frac{9y_2 -4}{11})[/tex]

Multiply through by 11

[tex](22,11) = (9x_2 -8,9y_2 -4)[/tex]

By comparison:

[tex]9x_2 - 8 = 22[/tex]

[tex]9y_2 - 4 = 11[/tex]

So, we have:

[tex]9x_2 - 8 = 22[/tex]

[tex]9x_2 = 22 +8[/tex]

[tex]9x_2 = 30[/tex]

Solve for x2

[tex]x_2 = 30/9[/tex]

[tex]x_2 = 3.3[/tex]

[tex]9y_2 - 4 = 11[/tex]

[tex]9y_2 = 11+4[/tex]

[tex]9y_2 = 15[/tex]

Solve for y2

[tex]y_2 =15/9[/tex]

[tex]y_2 =1.7[/tex]

So, the coordinates of B is:

[tex]B =(3.3,1.7)[/tex]

Answer:

13.85

Step-by-step explanation:

You square 16 and get 256. Then you square 8 ang get 64. then you subtract 64 from 256. You get 192, you square root that and get 13.85.

Answer:

56

Step-by-step explanation:

Angles w and 124 are linear pair angles,

w + 124 = 180

w = 180 - 124

w = 56

Answer:

x intercepts are (4,0) and (-6,0)

axis of symmetry is x=-1

vertex is (-1,-25)

Step-by-step explanation:

Answer:

x intercepts are (4,0) and (-6,0)

axis of symmetry is x=-1

vertex is (-1,-25)

Step-by-step explanation:

Answer:

Solution given:

9x-4=8+7x[Vertically opposite angle]

9x-7x=8+4

2x=12

x=12/2

x=6

:.8+7x=8+7×6=50°

Answer:

50

Step-by-step explanation:

9x - 4 = 8 + 7x

x = 6

Therefore, 8 + (7 *6) = 50

The measure of the angle is 50

Thenks and mark me brainliest :)))

Step-by-step explanation:

Hi,

Think about it this way.

20%

40%

60%

80%

100%

We had to add 20% 5 times in order to get 100%.

The same goes for the fraction.

1/5

2/5

3/5

4/5

5/5

We had to add 1/5 5 times to get it to 5/5.

So...

20% is the same thing as... 20/100 and simplified, it's the exact same thing as 1/5.

They're basically the same exact thing except they're written in different ways.

I hope this helps, I didn't really understand what you needed exactly, but if you need anything else, feel free to let me know :)

Have a wonderful day.

Answer:

  1) x = 4

  2) ? = 20

  8) x = 5

Step-by-step explanation:

Use the applicable relationships to write an equation involving the unknown. Solve the equation.

__

1) We note that the marked arcs are the same length. In a circle, chords that subtend arcs of the same measure are the same length.

  5x -1 = 4x +3

  x = 4 . . . . . . . . . . add 1-4x to both sides

__

2) A tangent meets a radius at right angles. The given triangle is a right triangle, so the Pythagorean theorem applies.

  12² +16² = x²

  144 +256 = x² = 400

  x = √400 = 20

The missing value is 20.

__

8. Tangents from the same point are the same length.

  4x -8 = 12

  4x = 20 . . . . . add 8

  x = 5 . . . . . . . divide by 4

_____

Additional comment

In problem 2, you note the ratio of side lengths is 12 : 16 = 3 : 4. This should give you a clue that this is a 3-4-5 right triangle. The long (missing) side will be 5, scaled by the scale factor of 4, so will be 4×5 = 20.

Answer:

767,000 in scientific notation is [tex]7.67*10^5[/tex].

Step-by-step explanation:

A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 and multiplied by a power of 10. In this case, if 767,000 were to be written in scientific notation, then you need to move the decimal place of the number until you have a number that meets the requirement above. 7.67 would be the number to use, and you need to multiply that by a power of 10 that makes the product the original number, so the power would be 5. So 767,000 in scientific notation would be [tex]7.67*10^5[/tex].
