Given a dilation with the origin o (0, 0), by observation determine the scale factor "k." do, k = (5, 0) (10, 0) the dilation an expansion. true false

The scale factor is 2 and the statement "The dilation an expansion" is true.

Step-by-step explanation:

The center of dilation is origin and dilation is rule is given as

The dilation with scale factor k with the center of dilation at origin is defined as

If k>1, then it is an expansion and if k<1, then it is a compression.

The formula for scale factor is

The scale factor is 2.

Since 2>1, therefore the given dilation is an expansion.

The scale factor is 2 and the statement "The dilation an expansion" is true.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
