Which of the following shows the figure rotated 90 degrees counterclockwise around the origin and then reflected across the x axis?

A

Explanation:

Transformation rule : The coordinates change by the rule when the figure rotate 90 degrees about the origin is given by

Transformation rule: When the figure reflected across x- axis then the coordinates change by the rule

The given figure cut x - axis at x=3

The coordinates (3,0).

After 90 degrees rotation about origin the coordinates becomes (0,3).

After reflection across x- axis , the coordinates becomes (0,-3).

Only in first figure, there is (0,-3) .

Hence, the option A is true.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
