If A is a set with 29 elements and B is a subset of A with 16 elements, what is the number of elements of A - B?
Questions # 2: A beekeeper lives adjacent to an apple orchard. The orchard owner benefits from the bees because each hive pollinates about one acre of apple trees. The orchard owner pays nothing for this service, however, because the bees come to the orchard without his having to do anything. There are not enough bees to pollinate the entire orchard, and the orchard owner must complete the pollination by artificial means, at a cost of $10 per acre of trees. Beekeeping has a marginal cost MC = 10 + 2Q, where Q is the number of beehives. Each hive yields $20 worth of honey. a. How many beehives will the beekeeper maintain? b. What is the socially optimal level of beehives? c. What do you conclude?

At room temperature, barium titanate belongs to point group 4mm. Write out the transformation matrices for the symmetry elements required to generate this tetragonal point group. Using Neumann's Principle, determine the pyroelectric and dielectric matrices.
Text: Assume that you will develop a system for a university library and want to collect requirements. Now, the information you have about this system is described by the scenario below: Consider a university library borrowing system. (Do not worry about catalog searching, etc.) The system will record the books owned by the library and will record who has borrowed what books. Before someone can borrow a book, he or she must show a valid ID card that is checked to ensure that it is still valid against the student database maintained by the registrar's office (for student borrowers), the faculty/staff database maintained by the personnel office (for faculty/staff borrowers), or against the library's own guest database (for individuals issued a "guest" card by the library). The system must also check to ensure that the borrower does not have any overdue books or unpaid fines before he or she can borrow another book. Every Monday, the library prints and mails postcards to those people with overdue books. If a book is overdue by more than two weeks, a fine will be imposed and a librarian will telephone the borrower to remind him or her to return the book(s). Sometimes books are lost or are returned in damaged condition. The manager must then remove them from the database and will sometimes impose a fine on the borrower. (1) Read the scenario and list use cases (note: if you need additional information to complete your design, please feel free to add) (2) Choose one of the use cases in (1) and create a use case form.
