    i will repeat don't bother if you dont understand the work! so dont waste my time or yours.

     

    research subject is : r/c helicopters,drones and the faa, i am against r/c aircraft registration( specificaly r/c helicopters)  

     

    i am looking for one tutor to do work with from this point on,if that is you then apply 

     

     

     

    Purpose:

    The purpose of the second draft is to build upon the first draft that you have already written and to move your drafting

    process forward so that you can add a body, conclusion, and abstract to the paper, making it a cohesive and whole

    academic paper.

    Description:

    In this assignment, you will take Draft 1 (review of literature), written in Unit IV, and write an introduction to your final

    Research Paper that sets the context for your project, establishes your argument, asserts your thesis, and allows for an

    easy transition from your review of literature. Your introduction alone should be between 250-350 words. If the introduction

    alone is less than this word count, it is likely you have not fully developed your introduction, and this lack of development

    can severely impact your grade for this assignment. Your Draft 2 should include the elements listed below.

    Elements:

    The grade of your second draft is largely based on your inclusion of these elements and the overall quality of your writing.

    For assistance, you may want to refer to the examples in Chapter 23, Section 23a, of Strategies for Writing Successful

    Research Papers (pp. 507-509). Your Draft 2 must contain the following elements.

    1. Cover page and APA formatting:

    You should include an APA-style cover page for your Research Paper Draft 2. See the example on page 16 of The

    CSU APA Guide (6th edition). Your cover page should include the following: the title of your paper, your name, and

    the name of your university (Columbia Southern University). The running head should include up to 50 characters

    from the title of the paper, along with a sequential page number in the upper right-hand corner.

    2. Introduction:

    Draft and revise an introduction between 250-350 words to come before your revised review of literature. There are

    some pitfalls to writing an introductory paragraph, and you can avoid some of them by reading through the

    Checklist: “Avoid Certain Mistakes in the Introduction” on p. 495 of Strategies for Writing Successful Research

    Papers.

    3. Review of literature:

    Using the comments that you received on your Draft 1, revise your review of literature, and include it with Draft 2.

    4. References:

    Include a references list as the last page of the paper. See the example on pages 6, 7, and 21 of The CSU APA

    Guide (6th edition). All entries are those that have been cited in the text. No others are to be included. No

    textbooks should be included on the references list.

        Polycorp Limited Steel Division is considering a proposal to purchase a new machine to manufacture…

        Polycorp Limited Steel Division is considering a proposal to purchase a new machine to manufacture a new product for a potential three-year contract. The new machine will cost $1.8 million. The machine has an estimated life of three years for accounting and taxation purposes. The contract will not continue beyond three years and the equipment’s estimated salvage value at the end of three years is $228,000. The tax rate is 28 percent and is payable in the year in which profit is earned. An investment allowance of twenty percent on the outlay is available. The after-tax cost of capital is 14.85%pa. Addition current assets of $76,000 are required immediately for working capital to support the project. Assume that this amount is recovered in full at the end of the three-year life of the project. The new product will be charged $159,500 of allocated head office administration costs each year even though head office will not actually incur any extra costs to manage the project. This is in accordance with the firm’s policy of allocating all corporate overhead costs to divisions. Extra marketing and administration cash outflows of $168,500 per year will be incurred by the Steel Division for the project. An amount of $129,000 has been spent on a pilot study and market research for the new product. The projections provided here are based on this work. Projected sales for the new product are 32,000 units at $143 per unit per year. Cash operating expenses are estimated to be 72 percent of sales (excludes marketing and administration, and head office items). Except for initial outlays, assume cash flows occur at the end of each year (unless otherwise stated). Assume diminishing value depreciation for tax purposes.Required(a) Construct a table showing your calculations of net cash flow after tax (NCFAT). Use the method shown in lectures and notes.(b) Calculate the NPV. Is the project acceptable? Why or why not?(c) Conduct a sensitivity analysis showing how sensitive the project is to operating expenses and to the cost of capital. Explain.(d) Write a short report explaining your calculation of relevant net cash flows after tax, justifying your selection of cash flows. Be sure to state clearly any assumptions made (implicit and explicit).
