How to define a dilation between two concentric circles</h3>
Two circles are <em>concentric</em> when they share the same center (
) but they have different radii (
), where 
corresponds to the radius of the <em>smaller</em> circle. By analytic geometry we know that circles are modeled after this formula:
(1)
If we assume that the center of dilation is the center of both circles and the dilation use a scale factor of . Then, we have the following expression:
(2)
The center of dilation has a coordinate of and the scale factor is . The <em>transformation</em> formula is .

Answer: 8 and 80
Step-by-step explanation:
8 * 5 = 40
8 * 10 = 80
8 must be the hcf of two separate numbers. So, one of them must be 8, and the other must be greater than 8.
Multiples of 8:
8
16
24
32
40
48
56
64
72
80
The numbers on that list that multiply evenly to 80:
8, 16, 40, 80
16 is the lowest common multiple of 16 and 8
40 is the lowest common multiple of 40 and 8
80 is the lowest common multiple of 80 and 8
So the two numbers are 8 and 80; the highest common factor (HCF) is indeed 8.
Y=0-14 i think is the amswer

does it equal to anything?
