Trapezoid pqrs is similar to trapezoid pꞌꞌqꞌꞌrꞌꞌsꞌꞌ. which transformations were performed on trapezoid pqrs to form trapezoid pꞌꞌqꞌꞌrꞌꞌsꞌꞌ? all dilations have a center of dilation at the origin and all rotations are around the origin. a. pqrs was reflected across the y-axis and then dilated by a scale factor of 4 to form pꞌꞌqꞌꞌrꞌꞌsꞌꞌ. b. pqrs was dilated by a scale factor of and then rotated 180° clockwise to form pꞌꞌqꞌꞌrꞌꞌsꞌꞌ. c. pqrs was dilated by a scale factor of and then translated 2 units right and 2 units down to form pꞌꞌqꞌꞌrꞌꞌsꞌꞌ. d. pqrs was dilated by a scale factor of 4 and then rotated 180° clockwise to form pꞌꞌqꞌꞌrꞌꞌsꞌꞌ.

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.
