Answer:
The 3rd one
Step-by-step explanation:
It is rotated 180 degrees so the little dot in the top right corner would now be at the bottom left corner and since it is dilated by a scale factor of 1/2 it would get smaller.
Answer:
i think 88
Step-by-step explanation:
(it's been a while since I've done this so I'm not too sure it's correct)
The formula we need to use is
2πr(angle/360)
we need the radius (r)
To get r we need angle AES
180-80= 100
using the equation from before
88=2πr*(100/360)
raidus: 50.42
Then to get the length CD we need angle DEC
180-80=100
2π*50.42*(100/360)=88
there probably was some kind of shortcut we could've used to figure this out faster but whatever
Answer:

Answer:
exponential
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Since the base is the same, 3, you can just get rid of it using the principles of log. What you're left with is:
2x + 1 = x + 5
Now just solve for x:
2x - x = 5 - 1
x = 4
