1.) Consider the symbolic mapping statement (x, y)↦(18x,18y).
what is the scale factor for this dilation?
2.) Triangle PQR has points P(−3,4), Q(−8,3), and R(−1,−6).
Triangle PQR is transformed using the mapping statement (x, y)↦(8x,8y) to create triangle P′Q′R′.
What are the coordinates of points P′, Q′, and R′ of the image?
a. P′(−3,32), Q′(−8,24), R′(−1,−48)
b. P′(−38,−12), Q′(−1,38), R′(−18,−34)
c. P′(−24,4), Q′(−64,3), R′(−8,−6)
d. P′(−24,32), Q′(−64,24), R′(−8,−48)
3.) Which symbolic mapping statement corresponds to the verbal mapping statement "A figure is dilated by a factor of 2, and the center of dilation is the origin"?
a. (x, y)↦(2x,2y)
b. (x, y)↦(x,2y)
c. (2x,2y)↦(x, y)
d. (x, y)↦(12x,12y)
4.) Match each verbal mapping statement to its corresponding symbolic mapping statement.
Assume that the center of dilation is the origin for all transformations.
Dilate by a factor of 5
Dilate by a factor of 1/5
Dilate by a factor of 1

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.
