Answer:
y = 3x^2 is compressed by 3.
As y = x^2 is the parent graph, you can see how big a difference 3 makes.
Hope this helps!
(Red: y = 3x^2)
(Blue: y = x^2)
this is easy just d0 206+519 and theres your answer you will get the answer to be 725 i hope this helps
Circumference = pi*diameter
C = pi*20
C = 20pi
When I used my calculator to compute 20*pi, I get approximately 62.83185
This is somewhat close to what choice C is saying. The difference is that choice C has an extra 1 buried inside it. I'm not sure if your teacher made a typo.
