Sound travels about 750 miles per hour. Suppose it takes about 3 seconds to hear the echo. How far away is the canyon wall, in feet feet
Now let's generalize that result. Suppose it takes n seconds to hear the echo. How far away is the Canyon wall, in terms of n?

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
