Answer: (-1, 2)

Step-by-step explanation:

<u>It's a counter-clockwise rotation, that means (x, y) changes to (y, -x).</u>

(-2, -1) ⇒ (-1, -(-2)) ⇒ (-1, 2)

<u>If it's a clockwise rotation, then (x, y) will change to (-y, x)</u>

(-2, -1) ⇒ (-(-1), -2) ⇒ (1, -2)

Answer:

volume = 10m^3

Step-by-step explanation:

This shape is called a rectangular prism. The formula for finding the volume of this prism is: volume = L * W * H

All you do is plug the values into the formula.

The length is 2m

The width is 1m

the height is 5m

Volume = (2m)(1m)(5m)

Volume = 10m^3
