Ok what is the difference between the centers?

Would it be 113? @ adamaero
adamaero
  • adamaero
How did you get that answer?
FLVSKidd
  • FLVSKidd
-3-4^2 + 1-9^2
FLVSKidd
  • FLVSKidd
I remember seeing that formula you showed me.
adamaero
  • adamaero
You need two equations (for each circle).
adamaero
  • adamaero
There may be a more straightforward way, but I haven't thought of it.

Can you give me an idea of what I need to do?
adamaero

I'll foil it out, but I'm not sure that I'm guiding you down the right path anyway...

I took the test, how I did it was by translation. Remember, these are word problems and math problems. What is the translation difference between the two?
FLVSKidd
  • FLVSKidd
do you have the answers? or was that way back

  • FLVSKidd
is there a formula for translation difference?

It was my semester exam too, I had to get an extension. No just plain translation, graph it. How far would it be across the board? In units, aka "I translated A up 4 units and across by 2"
FLVSKidd
  • FLVSKidd
Yeah I had to get an extension as well and I have 20 minutes to finish these questions.
FLVSKidd
  • FLVSKidd
less than
FLVSKidd
  • FLVSKidd
so I have to figure out how many units across the y and x it translated?
anonymous
  • anonymous
Ok mine was translated to the left and upwards. Explain the difference. Then what is the difference in dilation? Explain that difference.
FLVSKidd
  • FLVSKidd
what is dilation?
anonymous
  • anonymous
Expansion of an object. Primarily circles.
anonymous
  • anonymous
So what the explanation needs to be is something along the lines of "I proved they were similar by translating _________ and I dilated it ______" Make sense?
FLVSKidd
  • FLVSKidd
not really I get what you mean by dilation but doesnt similar mean the same angles?
anonymous
  • anonymous
Yes, its just larger. A radius of 4 can be dilated to 1/4 aka 1. So what you need to do is find the difference in location of the center point.
FLVSKidd
  • FLVSKidd
from circle c to circle e right?
anonymous
  • anonymous
What is the difference in units of (-3, 1) and (4, 9)? Go X axis first, then Y axis. Then what is the dilation difference? And yes, either way it works.
FLVSKidd
  • FLVSKidd
7 and 8 right?
FLVSKidd
  • FLVSKidd
or is it -7 and 8
anonymous
  • anonymous
Yes, explain it by saying something like "I translated it to the right by 7 on the x-coordinate, moving it from -3 to 4" For example of what you did.
FLVSKidd
  • FLVSKidd
and upwards 8 right?
anonymous
  • anonymous
Yes. Its to the right by 7 then upwards by 8 I think. Word it out. Then the dilation is 4, what is 3/4 of four?
FLVSKidd
  • FLVSKidd
3?
FLVSKidd
  • FLVSKidd
.75
anonymous
  • anonymous
Yes. That is your answer. Word it out.
FLVSKidd
  • FLVSKidd
3 or .75
FLVSKidd

@RhythmicTune

Something like "I proved they were similar by moving Circle C to the right by 7, moving -3 to 4. I then moved it upwards by 8...(fill in similar to first half here).. The dilation difference is 3/4.
anonymous
  • anonymous
Its 3 not .75
FLVSKidd
  • FLVSKidd
okay
anonymous
  • anonymous
I said it by saying one can be translated to the other then dilated.
FLVSKidd
  • FLVSKidd
thanks so much dude
