Abstract Algebra: Let . It has been shown already that K is the splitting field over , and the following isomorphisms are of onto a subfield as extensions of the automorphism , and also the elements of :
;
;
;
.
We also proved previously that is separable over . Based on all of those outcomes, find all subgroups of and their corresponding fixed fields as the intermediate fields between and , and complete the subgroup and subfield diagrams for them. Finally, establish the one-to-one correspondence between the subgroups and fixed fields that shows Galois Theory's main theorem.
Show all work fully, will rate

A firm's production function is when $50 has been paid, and zero otherwise. The unit prices of capital and labor are r = $27 and w = $4, respectively. This firm's long-run total cost function is: Score: 1 of 1 2. Suppose the capital input is fixed in the short-run at the level for the firm in question 1. What is the output level at which this capital amount is the long-run choice? Q = 53 Q = 12 Q...
Problem 8-35A (Part Level Submission) The Daniels Tool & Die Corporation has been in existence for a little over three years. The company’s sales have been increasing each year as it builds a reputation. The company manufactures dies to its customers’ specifications and therefore uses a job-order cost system. Factory overhead is applied to the jobs based on direct labour hours—the absorption-costing (full) method. Overapplied or underapplied overhead is treated as an adjustment to Cost of Goods Sold. The company’s...
