Question

HELP ME PLEASEEE???!!!??? FAN & MEDAL!


Polygon ABCD will be dilated by a scale factor of 2.2 with the origin as the center of dilation, resulting in the image A'B'C'D'. What will the slope and length of C'D' be?

A. m = undefined, C'D' = 13.2 units

B. m = 0, C'D' = 6.6 units

C. m = 0, C'D' = 13.2 units

D. m = undefined, C'D' = 8 units

Answer 4

Multiply 2.2 to points C and D.

Answer 5

A. m = undefined, C'D' = 13.2 units

Answer 6

Okay(: Are you sure @CO_oLBoY ? (:

Answer 7

i think so

Answer 8

Okay. I just dont want to get it wrong and fail it.

Answer 9

wait i'll check it again then

Answer 10

okay thank you.

Answer 11

C = (10, 6)
D = (10, 12)

2.2 * 10 = 22
2.2 * 6 = 13.2
2.2 * 12 = 26.4

So we have:

C' = (22, 13.2)
D' = (22, 26.4)

Line CD and C'D' will be the same but parallel.. And since CD is a straight line, then it will be undefined.

To find the distance between two points use the formula:

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

Here:

\(x_2 = 22\)
\(x_1 = 22\)

\(y_2 = 26.4\)
\(y_1 = 13.2\)

\(\sqrt{(22-22)^2 + (26.4-13.2)^2}\)

\(\sqrt{(0)^2 + (26.4-13.2)^2}\)

\(\sqrt{(0)^2 + (13.2)^2}\)

\(\sqrt{0 + 174.24}\)

\(\sqrt{174.24}\)

\(13.2\)

Answer 12

yup its A. m = undefined, C'D' = 13.2 units

Answer 13

Yay(: Okay! THANKS BOTH OF YOU! I wish i could give you both medals.

Answer 14

np :) and no need to give me a medal :)

Answer 15

Its okay. I did anyways. (:
