Kenny is planning for retirement in 20 years. Currently, he has $300,000 in a savings account
and $600,000 in a mutual fund. Moreover, he plans to add to his savings by depositing $3,000
per month in his savings account at the beginning of each month for the next twenty years
until retirement. The savings account will return 5% APR compounded monthly and the
investment in the mutual fund will return 8% compounded annually.
(a) How much money will Kenny have at retirement 20 years later?
(b)Kenny expects to live for 20 years after he retires and at retirement he will
deposit all of his savings in a bank account paying 2% APR compounded
monthly. If he wants to withdraw an equal sum of money at the end of
each month from the bank account for financing his daily expenses after
retirement, how much can he withdraw each time?
(c)If the yield to maturity of a bond is higher than its coupon rate, the par
value of the bond should be higher than its price, resulting in a discount
bond. Conversely, if the yield to maturity of a bond is lower than its
coupon rate, the par value of the bond should be lower than its price,
resulting in a premium bond. Critically discuss this phenomenon. (word

ROST Corporation is a manufacturer of a variety of kitchen utensils. In order to improve the
quality of existing products, the production manager of the company proposes to replace a
machine used in the molding process. As a financial manager of the company, you are
responsible for assessing the feasibility of this project. After a preliminary study, it is
estimated that the new project will generate additional sales revenue of $310,200 in each of
the next four years. It is known that the company faces a marginal tax of 26% and wants a
17% required rate of return. In addition, the company employs the straight-line method to
compute its depreciation. To finance the project, the company would have to borrow
$1,200,000 at 10% interest from its bank. Other findings of the study are presented as
follows:
Old Machine New Machine
Initial purchase price $1,120,000 $960,000
Tax life 20 years 4 years
Age 16 years 0 years
Expected salvage value $0 $0
Current market value $224,000 N.A.
Annual cash expense $360,000 $380,000
(a)
(b)
(c)
Determine the annual after-tax cash flows associated with this project.
Determine whether you would accept or reject the project if the net present
value rule is used.
Without doing any calculation, how would you reply to your boss if he told you
to evaluate this project by the internal rate of return rule rather than the net
present value rule? (word limit: 150 words)

I am trying to create a basic shell program in C that runs 10 commands and then quits. Only one word commands are required, like:

cal, date, ls, ps, pwd, who, quit

The part I am struggling with is passing the scanned command into my array in the child process to be executed using execvp().

Here is my code:

#include <stdio.h>
#include <string.h>
#include<stdlib.h>
#include<unistd.h>
#include<sys/types.h>
#include<sys/wait.h>
#include<readline/readline.h>
#include<readline/history.h>

#define MAX_CMD_NUMBER 10

int main()
{
   int i;
   char command[10];

   for (i=0; i< 10; i++)
    {
      printf("COMMAND-> ");
      fflush(stdout);
      scanf("%s", command); // takes in the user's single-string command
      if (strcmp(command, "quit") == 0)
         i = MAX_CMD_NUMBER; // terminate the loop
      else
         printf("Command #%d is: %s\n", i, command);
     }

printf("hello world (pid:%d)\n", (int) getpid());
int rc = fork();
    if (rc < 0) {
        // fork failed; exit
        fprintf(stderr, "fork failed\n");
        exit(1);
    }
    else if (rc == 0)
    {
        char *command[2];
        command[0] = strdup(command);
        command[1] = NULL;        
        execvp(command[0], command);
        printf("this shouldn't print out");
    }
      else
      {
        command = wait(NULL);
    }
    return 0;
}

Please paraphrase this paragraph into a short summary..

Good philosophical thinking takes time. Progress in good critical thinking is often very slow. The process of critical thinking can’t be called successful if it efficiently maximizes its inputs and outputs in the shortest measure of time: We do not produce thoughts in the mind like widgets in a factory. The reason for this is because good critical think- ing often needs to uncover that which subtle, hard to discern at first, and easy to overlook. I define subtlety as ‘a small difference or a delicate detail which takes on greater importance the more it is contemplated.’ As a demonstration, think of how many ways you can utter the word ‘Yes’, and mean something different every time. This also underlines the importance of precision, as a good thinking habit. As another example: Think of how the colour planes in a painting by Piet Mondrian, such as his ‘Composition with Yellow, Blue, and Red’ have squares of white framed by black lines, but none of the white squares are exactly the same shade of white. You won’t notice this if you look at the painting for only a few seconds, or if you view a photo of the painting on your computer screen, and your monitor’s resolution isn’t precise enough to render the subtle differences. But it is the job of reason to uncover those subtleties and lay them out to be examined directly. And the search for those subtleties cannot be rushed.

Pam Alvarez and Shawna Jones are senior vice-presidents of Mutual of Whitewater. They are co-directors of the company’s pension fund management division, with Alvarez having responsibility for fixed income securities (primarily bonds) and Jones being responsible for equity investments. A major new client, the Southwestern Municipal Alliance, has request that Mutual of Whitewater present an investment seminar to the mayors of the represented cities, and Alvarez and Jones, who will make the actual presentation, have asked you to help them.

          To illustrate the common stock valuation process, Alvarez and Jones have asked you to analyze the Temp Que Company, an employment agency that supplies word processor operators and computer programmers to businesses with temporarily heavy workloads. Stocks of companies with similar risk as Temp Que are currently yielding 13%. You are to answer the following questions (Show calculations clearly).

1) Suppose Temp Que is expected to experience zero growth during the first 3 years and then to resume its steady-state growth of 6 percent in the fourth year. What is the stock’s value now?

2) Why do stock prices change? Answer the question by using the following example: Suppose the expected D₁ is $2, the growth rate is 5 percent, and R is 10 percent. Using the constant growth model, what is the price? What is the impact on stock price if g is 4 percent or 6 percent? If R is 9 percent or 11 percent?

The purpose of this assignment is to analyze data and use it to provide stakeholders with potential answers to a previously identified business problem.

For this assignment, continue to assume the role of a data analyst at Adventure Works Cycling Company. Evaluate the data associated with the drop in sales for the popular model "LL Road Frame-Black 60." Provide a hypothesis on what could be contributing to the falling sales identified in the initial business problem presented by your manager.

In 250-500 words, share these recommendations in a Word document that addresses the following.

1. Summary of the business problem including the requestor who initially brought the problem to you.
2. Summary of the data that were requested and how they was obtained.
3. Discussion of the limitations of the available data and ethical concerns related to those limitations.
4. Hypothesis of why sales of the popular model have dropped based upon data analysis. Reference the Excel file that summarizes the data findings that resulted from your queries.
5. Recommendations for addressing the business problem.
6. In addition to the report, the manager has requested that you submit the Excel files summarizing the data findings that resulted from your queries.
7. The manager has also requested that you update the ERD you created in the Topic 5 assignment to include the tables generated as a result of the joins completed in the Topic 6 assignment. The ERD should clearly document the work stream and relationships.

Porsche is expected to sell approximately 60,000 cars in the U.S. in 2019. I'll let you estimate an average selling price across Porsche models. For this example, let's assume that all the sales happen in December of 2019. Also, assume that Porsche has fully hedges their U.S. dollar exposure (based on predicted sales) using futures or forward contracts at a rate of $1.10 per Euro. What happens in the following situations:

a. the Dollar/Euro exchange rate remains unchanged and sales are as predicted

b. the Euro rises against the Dollar and the exchange rate moves to $1.00 per Euro. Sales are as predicted.

c. the Euro falls against the Dollar and the exchange rate moves to $1.25 per Euro. Sales are as predicted.

d. the Euro rises against the Dollar and the exchange rate moves to $1.00 per Euro. Sales are 20% higher than expected.

e. the Euro rises against the Dollar and the exchange rate moves to $1.00 per Euro. Sales are 20% lower than expected.

Be specific in your answers. Where does Porsche lose money, and how much? Where does Porsche make money and how much? What is the overall effect on Porsche's income in their home currency? FYI, you can make the Euro currency symbol in Word by using CRTL + ALT + E.
