Question

Circle A has center of (6, 7) and a radius of 4 and circle B has a center of (2, 4) and a radius of 16. What steps will help show that circle A is similar to circle B?

Translate circle A using the rule (x+4, y+3).

Rotate circle A 45° about the center.

Dilate circle A by a scale factor of 4.

Reflect circle A about the origin.

Answer 7

so... what would be your 1st step anyhow?

Answer 8

use the distance formula ??

Answer 9

well, you're expected to make the small one as the bigger, size and location
or the bigger as the small one, size and location

Answer 10

the bigger as the small one

Answer 11

well, either really, to look like the other

Answer 12

then

Answer 13

then you'd show that both are similar

Answer 14

how

Answer 15

so... look at the picture with both.... what would be the 1st step you'd take?

Answer 16

you're given a few steps to take, some are valid, some are not
so from the choices, what steps would you take, is more or less what's being asked

Answer 17

last one

Answer 18

so is it wrong ?

Answer 19

keep in mind that, one is bigger, and their center differ
so if the sizes differ.... wouldn't you firstly want to change their size?

Answer 20

one question what does Translate circle A using the rule (x+4, y+3). mean???

Answer 21

translate, or transform, or "move about" the figure
(x+4, y+3) if the original, "preimage" point was at say ( 8, -3) then the translated version will be at (8+4, -3+3 )

Answer 22

so the original "x-coordinate" gets shifted by +4 units
and the original "y-coordinate" gets shifted by -3 units

Answer 23

woops.... I meant... +3 units rather

Answer 24

(8,-3)
(8+4,-3+3)
(12,0)

Answer 25

yeap, in that example, yes, thus (12,0) is the TRANSLATED version of (8, -3), using the rule of (x+4, y+3)

Answer 26

ah so will the first one be the correct answer ??

Answer 27

"What \(\bf\large steps\) will help show that circle A is similar to circle B?"

Answer 28

what the meaning of Rotate and Dilate

Answer 29

dilate = expand, swell, blow up

Answer 30

i think Rotate is the correct answer

Answer 31

are you supposed to pick only one of choices?

Answer 32

yes

Answer 33

anyhow... from what I read... most of the choices don't apply I dont' think

well... notice the radius of A and the radius of B
A radius is 4
B radius is 16
4 * 4 = 16 <-- that is, 16 is 4 times 4, or 4 SCALED by a factor of 4

Answer 34

so to show the similarity, you'd really need 2 steps, translation and dilation
so... in this case none of the choices provide the former, so is the latter

Answer 35

i think that is the 3rd one is the answer
cuz Dilate circle A by a scale factor of 4

Answer 36

tis the only valid one, yes
circle A is 4, circle B is 16
so firstly to make A look like B, you'd blow it up to B size, by how much? well, 4*4 =16, so a factor of 4

Answer 37

4 and 16 in radius that is =)

Answer 38

yes the last one is correct we did it yaya

Answer 39

CORRECTION!! THE CORRECT ANSWER IS
Dilate circle A by a scale factor of 4.
i just took the test!
