Suppose a firm the following production function: f(x1,x2)=x_1^(1/2) x_2^(1/2)

This firm purchases inputs and sells output in competitive markets. The price of output is $10 per unit and the prices of the inputs x1 and x2 are $10 and $2 respectively. In the short run x2 is fixed and equal to 16. The marginal product for input 1 is: MP1=4/(x_1^(1/2) )

a) What is the profit maximizing level of input 1 for this firm to hire?
b) What is the profit maximizing level of output and the associated level of profits?
c) Derive a function describing isoprofit lines for this firm. Calculate and describe the slope of an isoprofit line for this firm.
d) Suppose the price of input 1 increases to $20. Use your isoprofit function to find the optimal amount of input 1 for this firm to hire.

A box with mass m is dragged across a level floor having a coefficient of kinetic friction ?k by a rope that is pulled upward at an angle ? above the horizontal with a force of magnitude F.

Part A

In terms of m, ?k, ?, and g, obtain an expression for the magnitude of force required to move the box with constant speed.

Part B

Knowing that you are studying physics, a CPR instructor asks you how much force it would take to slide a 90-kg patient across a floor at constant speed by pulling on him at an angle of 25? above the horizontal. By dragging some weights wrapped in an old pair of pants down the hall with a spring balance, you find that ?k=0.35. Use the result of part A to answer the instructor's question.

Write a program that creates three identical arrays, list1, list2, and list3, of 5000 elements. The program then sorts list1 using bubble sort, list2 using selection sort, and list3 using insertion sort and outputs the number of comparisons and item assignments made by each sorting algorithm.

Please use the file names listed below since your file will have the following components:

The table below uses data for the year 2014, adjusted to be comparable to each other. All population values are in thousands.

Instructions: Round your answers to one decimal place.

a. Fill in the blanks in the table above.

b. In part a, you should have found that the unemployment rates of the three countries differ significantly from one another. Select the possible reasons to explain why the countries might have different unemployment rates.

Germany could be in a recession and have higher cyclical unemployment, or .Germany could have more powerful unions. or Germany could have higher (and binding) minimum wages. or Japan could have a more liberalized labour market leading to lower frictional unemployment. or Germany and France could have more generous employment benefits. or All of the choices are correct.

Calculate the required area of flexure steel bars for a balanced rectangular section of a simply supported beam 3.5 m long, sustaining a total uniform service load of 15 kN/m and a concentrated service load of 50 kN at midspan.  Use Working Stress Design Method with b = 0.5d, f'_c = 21 MPa, f_s = 170 MPa, concrete cover of 40 mm, stirrup diameter of 10 mm and rebar diameter of 16 mm.

Describe the QE policy. How did the Fed’s balance sheet change? How does QE compare to traditional open market operations?

Qualified Tuition Programs (QTP) allows taxpayers to buy in-kind tuition credits for qualified higher education expenses or to contribute to an account.

What are the inclusions of in-kind tuition credits for qualified higher education expenses and the contribution to the educational incentive account? Explain.

***USING C++***

(a) Write a program that reads a text file in which each line in the file consists of a first name, a last name, following by 4 grades (double types) like Tim Hanes 78.3 98.0 80.5 72.3 The program must read every line of the text file, find the average of the 4 grades then print the names followed by the averages (one name per line) in a second file as well as on the monitor. Create the text file with at least 5 entries with the format given in part (a). Give the absolute path of the file in your computer. Test your program in part 2(a) on this file.

Can you show how you would write the 5 entries with notes

1. In the 30 June 2018 annual report of Baker and Anderson Ltd, the equipment was reported as follows:

      Equipment                                                    $650,000

      Accumulated depreciation                         ($280,000)     $370,000

The equipment consisted of two machines, Machine X and Machine Y. Both machines are measured using the cost model and depreciated on a straight-line basis over a 10-year period. As at 30 June 2018, these machines were reported as follows:

Machine X – Cost                                        $380,000

Carrying amount                                          $190,000

Machine Y – Cost                                        $270,000

Carrying amount                                          $180,000                                                      

On 31 December 2018, the directors of Baker and Anderson Ltd decided to change the basis of measuring equipment from the cost model to fair value model. Machine X was revalued to $200,000 with an expected useful life of 6 years, and Machine Y was revalued to $160,000 with an expected useful life of 5 years.

On 1 July 2019, Machine X was assessed to have a fair value of $175,000 with an expected useful life of 5 years, and Machine Y’s fair value was $143,000 with an expected useful life of 4 years.

Required:

1. Prepare the revaluation journal entries for both Machines X and Y required for the event on 1 July 2019 (5 journal entries required). Show all workings.

C++ , please answer both

1) Code a function object class which can scale data toward a desired maximum given the actual maximum and the desired maximum. (Reminder: to scale a value v use v*desired/actual.)

then after this

2) Show how to use your function object class from above to fix the following test scores. (What kind of loop would be most appropriate?) (Hint: What is the desired maximum of a typical test?)

double scores[MAX] = { 42, 55.5, 82, 74.5, 62 };

Q1) A(n) 8.3% bond matures in 7 years and has a current yield (not YTM) of 6%. The bond's current trading price is $________.

Q2) A 4% coupon bond with 6 months remaining until maturity is currently trading at $997.26. Assume semi-annual coupon payments. The bond's YTM is__________%.

If you can do both, please do! Thank you.
