Answer:
I think it would be 87.5 as an average between 85 and 90.
Step-by-step explanation:
Cos(x) = 10.5 / 20
cos(x) = 0.525
answer
C.
x = 58.3"
Translate Circle A (x-3, y+5) and then dilate by a scale factor of 3/8 or 0.375
Y= 12 -3x so if you take x as 0 y=12 x=1 y=9 x=2 y=6
(0, 12) (1,9), (2,6) are on the graph
Answer:
A
Step-by-step explanation:


Remember that
x^(b-c)
Using that
=3^(1/2x-1/2)=3^((x-1)/2)

So we can say:
, because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
