for this one i got  (+5 , - 6)          3/4        are these the correct?

 

2.

Why is circle 1 similar to circle 2?

Circle 1: center  (2, 3) and radius 4

Circle 2: center  (2, 3) and radius 12

A. Circle 2 is a dilation of circle 1 with a scale factor of 3.

B. Circle 1 and circle 2 are reflections of each other.

C. Circle 2 is a dilation of circle 1 with a scale factor of 8.

D. Circle 1 and circle 2 have the same center.

 

This is the answer i got is it right? A. circle 2 is a dilation of circle 1 with a scale factor of 3

 

3.

 

I think its 1.Circle Q is a translation of circle P, 6 units up.

 

2.Circle Q is a dilation of circle P with a scale factor of 7

 

is it correct

 

4.

According to these three facts, which statements are true?

  • Circle W has center  (−3, 0) and radius 8.
  • Circle V is a translation of circle W, 2 units down.
  • Circle V is a dilation of circle W with a scale factor of 2.

 

Select each correct answer.

 

The radius of circle V is 16.

 

The center of circle V is (−5, 0).

 

Circle V and circle W have the same center.

 

Circle V and circle W are similar.

 

i got option 1 the radius of circle v is 16

 

5.

Suppose x is any positive number.

Circle 1: center (−7, 4) and radius 8x

Circle 2: center (−7, 4) and radius 2x

 

Why is circle 1 similar to circle 2?

 

A. Circle 1 is a dilation of circle 2 with a scale factor of 0.25.

 

B. Circle 1 is congruent to circle 2.

 

C. Circle 1 is a dilation of circle 2 with a scale factor of 4.

 

D. Circle 1 and circle 2 have the same diameter.

 

Is this the answer? Circle 1 is a dilation of circle 2 with a scale factor of 4.

1.    Correct   !!!!

 

2.   Not sure about this...but... I believe that you are correct

 

3.   Correct !!

 

4. The radius of circle V is 16.  Correct!!

Also...Circles V  and W  are similar because all circles are similar...

 

5. Correct  !!!

 

 

cool cool cool
