Answer:

(-6, 7)

Step-by-step explanation:

the original and new points are both six units above/below the x-axis and 7 units to the right/left of the y-axis

Answer:

(-6,7)

Step-by-step explanation:

The rotation is 180 degrees, so its means that the direction (clockwise vs counterclockwise) doesn't actually matter. With a rotation of 180 degrees, the preimage is switched to the opposite side of both the y and x-axis. This means that the rule for rotation around 180 is (-h,-k). Therefore, the answer will have the opposite signs. Thus. the image of (6,-7) is (-6,7).

Answer:

Below.

Step-by-step explanation:

I'll do number 20, 21, 22 for you.

20. It is ±1, ±2, ±4, ±8.

21. Reflected over the x-axis and down 4.

22. Common ratio = 25/5 = 5.

23. Imaginary roots occur in pairs so there is also a root -5i.

The answer is c.

19. Option (a).

This is a translation of 4 to the left ( due to the (x + 4).

Geometry!!!!!!!!!!!!!!!!!!!!!!!!

Stella [2.4K]

<u>Given</u>:

Given that O is the center of the circle.

The radius of the circle is 3 m.

The measure of ∠AOB is 30°

We need to determine the length of the major arc ACB

<u>Measure of major ∠AOB:</u>

The measure of major angle AOB can be determined by subtracting 360° and 30°

Thus, we have;

$Major \ \angle AOB=360-30$

$Major \ \angle AOB=330^{\circ}$

Thus, the measure of major angle is 330°

<u>Length of the major arc ACB:</u>

The length of the major arc ACB can be determined using the formula,

<u></u> $m \widehat{ACB}=(\frac{\theta}{360})2 \pi r$ <u></u>

Substituting r = 3 and $\theta=330$ , we get;

$m \widehat{ACB}=(\frac{330}{360})2 \pi (3)$

$m \widehat{ACB}=\frac{1980}{360}\pi$

$m \widehat{ACB}=5.5 \pi$

Thus, the length of the major arc ACB is 5.5π m

What are the coordinates or point C on directed line segment AC, with A(2,-1) and C(x,y), or which point B(4,2) partitions the s

bogdanovich [222]

Answer:

$C(x,y) = (\frac{10}{4},\frac{-1}{4})$

Step-by-step explanation:

Given

$A(x_1,y_1) = (2,-1)$

$B(x_2,y_2) = (4,2)$

Required

Partition = 1:3

Here, we'll make use of the following formula:

$C(x,y) = (\frac{nx_1 + mx_2}{m + n},\frac{ny_1 + my_2}{m + n})$

<em>Where</em>

$m:n = 1:3$

Substitute values for m,n,x1,x2,y1 and y2

$C(x,y) = (\frac{3 * 2 + 1 * 4}{1 + 3},\frac{3 * -1 + 1 * 2}{1 + 3})$

$C(x,y) = (\frac{10}{4},\frac{-1}{4})$
