(2) S is the set of all functions which are linear combinations of the functions {1,cosnt,sinnt|ninZ}, and R is the set of all functions that map R->R. (3) S is the set of real matrices of the form ([a,b],[-b,a]), and R is the set of all real 2 imes 2 matrices. Problem 13. For each case, decide whether or not S is a subring of R.

Listen A wheat farmer sells wheat in a perfectly competitive market and hires labour in a perfectly competitive market. The market price of wheat is $2 a bushel, the wage rate is $10, the farmer employs five workers and the marginal product of the fifth worker is 3 bushels. What would you advise this farmer to do? A) Do nothing because the wage rate and the marginal product of the last worker hired are equal. B) Reduce employment because the wage paid is more than the marginal revenue product. C) Reduce the product price so that the wage and marginal revenue product will be equal. D) Increase employment because the wage paid is less than the marginal revenue product.
