Suppose a small business has sales of $14,000 this month, with future sales expected to grow by $1,000 each month. Costs consist of a fixed component, which is $8,400 per month, and a variable component, which is 25 percent of sales. Design a spreadsheet to compute the gross profit (revenue less fixed and variable costs) per month over a nine month period. What is the gross profit in a single month 5 months from now?

- A company has several employees, all with different names, who perform interviews with job applicants (one applicant is interviewed by one employee). The job applicants also have different names. The interviewer makes appointments for interviews with the applicants. Each applicant may be interviewed at several occasions, possibly by different interviewers, but in that case the interviews take place during different days. The company has special interview rooms. Each interviewer uses the same room for all interviews during a day. A room may, however, be used by different interviewers during a day, as long as the interviews don't collide in time. The reservation of interview appointments is to be computerized. The database devel- oper has decided to use a single relation for all data, with the following schema: Interviews(interviewer, applicant, day, time, room) a) From the text, find functional dependencies in the relation. b) Find the keys of the relation. c) Show that the relation is…Develop a VBA function to take the square root of the sum of the squares of two numbers.

- Use the following classes to draw a basic POS System Class Diagram. Customer Vendor Products Pricelist TransactionsSuppose you are organizing a conference where researchers present articles they have written. Researchers who want to present an article send a paper to the conference organizers. The conference organizers have access to a committee of reviewers who are each willing to read up articles each. Each paper submission gets reviewed by up to reviewers. Moreover, each submission has a particular topic and each reviewer has a specialization for a set of topics, so papers on a given topic only get reviewed by those reviewers who are experts on that topic. The conference organizers need to decide which reviewers will review each article (or equivalently, which articles will be reviewed by which reviewers). Explain how they could use a flow network to solve this problem.A warehouse is where the company stores its products and the storage bins in the warehouse are specified identified to their aisle, location in the aisle, and its shelf.
