Last week the number of bacteria in a petri dish was 2.25×10^2. This week the number of bacteria in the petri dish is 2.75×10^5. How many times more bacteria are in the petri dish this week? Round the decimal to the nearest tenth.

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.
