A) determine which amounts of postage can be formed using just 3-cent and 10-cent stamps.
b) prove your answer to (a) using the principle of mathematical induction. be sure to state explicitly your inductive hypothesis in the inductive step.
c) prove your answer to (a) using strong induction.
how does the inductive hypothesis in this proof differ from that in the inductive hypothesis for a proof using mathematical induction?

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
