A researcher estimates that a fossil is 3200 years old. Using carbon-14 dating, a procedure used to determine the age of
an object, the researcher discovers that the fossil is 3600 years old.
a. Find the percent error.
b. What other estimate gives the same percent error?
Explain your reasoning.

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.
