5/10 x 1 = 5/10 = 0.5
---------
5/10 x 2 = 10/10 = 1
5/10 x 3 = 15/10 = 1.5
5/10 x 4 = 20/10 = 2.0
5/10 x 5 = 25/10 = 2.5
Scientific notation helps you right big numbers but in smaller forms which can be very useful when answering a question on a test that you have a limited amount of time on.
I’m pretty sure it’s only pink because green and orange are the same and their point is a bit shorter!
Answer:
the origin, (0, 0)
Step-by-step explanation:
The coordinates of A' are 1/2 those of A, meaning each has been multiplied by the scale factor 1/2. When the dilated points are all the original points multiplied by the scale factor, the center of dilation is the origin.
_____
For center of dilation Q, the image of a point A after dilation by a factor of k is ...
A' = kA + (k-1)Q
Then for points A, A', and dilation factor k, the center of dilation can be found to be ...
(A' -kA)/(k-1) = Q
Here, that is ...
Q = ((-2, -2) -(1/2)(-4, -4))/(1/2 -1) = (0, 0)/(-1/2)
Q = (0, 0)
Yes, the perimeter of a square is ALWAYS four times the length of one of its sides; so the perimeter is proportional to the square's side length.
