Yanis fires pottery in a kiln. he decides to measure the rate of change of temperature of the pottery over time. what would be an appropriate unit for yanis's purpose?

For your rate of change, you could use the number of degrees over the number of minutes.

In the numerator, you could put the difference in the number of degrees. In the denominator, you could put the difference in the number of minutes.

The answer to your question is i think 7

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
