(80 POINTS) What rule describes a dilation with a scale factor of ½ and the center of dilation at the origin?

lesya [120]

Answer:

Step-by-step explanation:

(x, y) -> (1/2x, 1/2y)

When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)

1. A ladder 17 feet long is leaned up against a house,

zepelin [54]

Answer:

The base of the ladder has a length of 8 ft.

Step-by-step explanation:

We have to draw a triangle, as the figure attached.

The hypothenuse of the triangle is the length of the ladder (17 ft).

The height on the wall that the ladder reach is the adjacent (15 ft).

The base of the ladder is our unknown quantity X.

We will use the Pythagorean theorem to express the relation between these numbers:

$c^2=a^2+b^2\\\\17^2=15^2+x^2\\\\x^2=17^2-15^2=289-225=64\\\\x=\sqrt{64}=8$

The base of the ladder has a length of 8 ft.
