The function A (r)=ar2 gives the area of a circular object with respect to its radius r. Enter the inverse function r(A) to find the radius r required for area of A . Then estimate the radius of an
circular object that has an area of 80 cm2.
The inverse function is r(A) =
The radius of a circular object rounded to the nearest tenth is r (80) –
cm?

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.
