The main rotor of a helicopter is spinning at a constant rate. The rotor makes 80 revolutions every
12 seconds. At what rate, in revolutions per minute,
is the rotor spinning?

Its equal to d=7.07in

Your answer should be 1/3. i hope i could ! good luck : )

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

Need the graph to answer this.
