Unreadable work will receive nocredit.You should provide well-written, complete answers to each of the questions. We will look forcorrect mathematical arguments, complete explanations, and correctshould be formulated in complete sentences. As appropriate, you may want to include diagrams orequations written out on a separate line. You may read your textbook to find examples of how weise of English. Your solutioncommunicate mathematics.Students are encouraged to use word-processing software to produce high quality solutions.However, you may find that it is simpler to add graphs and equations using pen or pencil.et- x – 11. Evaluate limx→0 COS x – 12. A warehouse selling cement has to decide how often and in what quantities to reorder. It ischeaper, on average, to place large orders, because this reduces the ordering cost per unit.On the other hand, larger orders mean higher storage costs. the warehouse always reorderscement in the same quantity, q. The total weekly cost, C, or ordering and storage is given byaC =+ bą,where a and b are positive constants.(a) Which of the terms a/q and bq represents the ordering cost and which represents thestorage cost?(b) What value of q gives the minimum total cost?
