Answer:
Option B. 
Step-by-step explanation:
step 1
Find the area of a circle with radius 8.5 inches
The area of a circle is equal to

substitute


step 2
Find put the approximate area of the fan
we know that
The area of complete circle subtends a central angle of 360 degrees
so
using proportion
Find the area that correspond a central angle of 125 degrees

assume


I’m so sorry but I don’t have a clue! But you’ll get it eventually
The answer is A
as the x+ 4 is when we replace x with 0
x=0
so
y=0+4
=4
So the line of y must intersect at (0,4) coordinate
which is given as in A and should be a positive slope
Step-by-step explanation:
Scale factor of STUV to S'T'U'V
= Length of T'U' / Length of TU
= 6/12 = 0.5.
