Consider this scenario: The population of a city increased steadily over a six-year span. The following ordered pairs show the population and the year over the six-year span (population, year) for specific recorded years. Use linear regression to determine a function y, where the year depends on the population x, to five decimal places of accuracy. (3,600, 2000), (4,000, 2001), (4,750, 2003), (6,050, 2006) According to this model, what is the population in 2015? (Round your answer to the nearest...
3. Find the domain, asymptotes, and x-intercepts of the function, and then sketch its graph: f(x) = log(3 - x) 4. State the amplitude, period and phase-shift, and then sketch one complete cycle of the graph: y = 2cos (4x + Tt). Label all the maximum, minimum, and x-intercepts. 5. In 2002, the population of a colony is 50,000 and is increasing exponentially at 2.5% per year. a) What will the population be after 6 years? b) In what year...

The Flower City Grocery is faced with the following budgeting decision. Its display freezer system should be repaired. But to repair may not be the correct approach. Rather the company could purchase a new freezer system for $15,000. The new freezer system has more display space and will increase profits. With the new system net cash inflows will average $8,000 and cash operating costs will be $3,000 annually. The company has a cost of capital of 9 percent. The tax...
