Answer:
The image is (-18,0)
Step-by-step explanation:
Here, we want to find the image of the given point after dilation by the given scale factor
Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;
(kx , ky)
Applying this in the given scenario, we have
(2(-9) , 2(0))
= (-18,0)

Step-by-step explanation:
Answer:
110
Step-by-step explanation:
There is a theorem that says "The measure of an angle formed by a secant and a tangent drawn from a point outside the circle is HALF the difference of the intercepted arcs "
Hence we can say:

We can say:

Also, we know that circle's degree measure is 360, thus we can say:

To find Arc AB, we can use the two equations and add, thus we get:

Thus, arc AB = 360 - 250 = 110
2nd answer choice is right.
