Write a library of static methods that performs various geometric transforms on polygons. mathematically, a polygon is defined by its sequence of vertices (x 0, y 0), (x 1, y 1), (x 2, y 2), …. in java, we will represent a polygon by storing the x– and y-coordinates of the vertices in two parallel arrays x[] and y[].

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
