Answer:
Step-by-step explanation:
Given formula to find the area:
Find radius first:
The circumference in this situation would be 38 feet.
Since we need to find radius, do division to 38 by 6.28.
Our radius is 6.05
Now back to the original formula which is:
Substitute:
5x-7y=10
-7y=10-5x
y=(10-5x)/-7
y=10/-7-5x/-7
y=5x/7-10/7
hence C is correct option
Answer:
9.28

Answer:
rotation of 270°
Step-by-step explanation:
Consider the coordinates of of preimage and image of ABC
A(1, 0 ) → A'*0, - 1 )
B(6, - 7 ) → B'(- 7, - 6 )
C(0, - 4 ) C'(- 4, 0 )
What we note is the x- coordinate of the image is the y- coordinate of the preimage and the y- coordinate of the image is the negative of the x- coordinate of the preimage, that is
(x, y ) → (y, - x )
This is equivalent to a counterclockwise rotation about the origin of 270°
