segment CD has endpoints at C(0, 3) and D(0, 8). If the segment is dilated by a factor of 2 about point C, what is the length of
MatroZZZ [7]

The length of the image of the segment CD is 10 units if the segment CD has endpoints at C(0, 3) and D(0, 8).

<h3>What is a distance formula?</h3>

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have two points C(0, 3) and D(0, 8)

The distance between these two points:

d = √(8-3)²

d = 5 units

The length of the image of segments CD = dilation factor×length of CD

= 2×5

= 10 units

Thus, the length of the image of the segment CD is 10 units if the segment CD has endpoints at C(0, 3) and D(0, 8).
