Will mark !

the image of abc is a'b'c. what transformations would result in this image?

abc is reflected over the line x = 1, then is rotated -90° around the origin.
abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1).
abc is rotated 90° around the origin, then is reflected over the y-axis.
abc is rotated -90° around the origin, then is reflected over the line y = -1.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

only 10/60 isn't equivalent

hope this : )

dont know
