craft corp's production function is given by q = 5min(K, 2L), where q is the quantity produced and K and L are the amounts of capital and labor input. Input prices are r = 2 and w = 6.

a) find the long run cost function

b) draw the isoquants and isocost and show the equilibrium when q = 2000. what is the total cost to produce q = 2000? what is the labor cost to produce q = 2000? what is the capital cost to produce q = 2000?

c) supposed in the short run K is fixed @ 20. find the short run cost function. represent the short-run and long-run cost functions in a diagram together.

Caspian Sea Drinks is considering buying the J-Mix 2000. It will allow them to make and sell more product. The machine cost $1.78 million and create incremental cash flows of $820,427.00 each year for the next five years. The cost of capital is 10.84%. What is the net present value of the J-Mix 2000?

Q7. General Electric Corp. (GE) paid cash dividends totaling $0.57 per share in 2000. Over the previous three years, GE's dividends grew at an annual rate of 15.4 per-cent. Assume that this growth rate will continue for five more years, after which dividend growth will revert to a normal annual rate of 8 percent into perpetuity. Also assume that the appropriate discount rate for GE is 11 percent. a. Compute the value of GE's stock at year-end 2000. b. The actual price of GE stock at year-end 2000 was $47.9375. Comparing this price to your calculation of GE's value in (a), was GE overpriced or underpriced at year-end 2000?

The Consumer Price Index (CPI) is the most popular indicator of inflation.  Consider the price and consumption data given below.

(a)     Using 2000 as the base year compute the value of the CPI for the years 2003 and 2004            (2000 = 100).

(b)     Briefly interpret your results using the CPI that you have calculated.

(c)     Compute the annual inflation rate for the years 2003 and 2004.

Based on analysis of its assets, Nike was more liquid in 2019 than in 2015.

Nike had less money invested in inventory in 2019 than in 2015.

Nike had relatively more money invested in PP&E in 2019 than in 2015

).Modify the project so that records are inserted into the random access file in ascending order using an insertion sort methodology with the Social Security Number acting as the key value. This requires defining the method compareTo() in the Personal and Student classes to be used in a modified method add() in Database. The method finds a proper position for a record d, moves all the records in the file to make room for d, and writes d into the file.

2. With the new organization of the data files. find() and modify() must also be modified. Both methods should now stop their sequential search when they encounter a record greater than the record looked for, or they reach the end of the file.

Can somebody check the compareTo() and help me out with the add() method in this question.
