Create a matlab function that converts Miles per hour to feet per second. Please show code in matlab

For this portion of the lab you will design the solution so that you perform some conditional tests. For this lab: 1. You will validate input to ensure that the user enters inputs within a certain range or larger than a certain minimum value. You will validate the inputs as follows: (LO 1, 2, 3) a. The user cannot enter a negative number for: i. Miles to kilometers ii. Gallons to liters iii. Pounds to kilograms iv. Inches to centimeters b. The user cannot enter a value above 1000 degrees for Fahrenheit to Celsius (LO1) c. You MUST design a logical program exit. You may NOT use exit, break, quit, or system exit, or ANY OTHER forced exit. Do not use a menu. Use LOGIC to exit the program. 2. If the user enters an invalid value, then the program will issue an error message and terminate immediately. (Do NOT accept further data). 3. Save the program as firstname_lastname_Lab3a.py where you will replace firstname and lastname with your actual first and last name. 4. Test all conditions prior to submitting.

The production department of Zan Corporation has submitted the following forecast of units to be produced by quarter for the upcoming fiscal year:

Units to be produced:

1st Quarter = 5,400
2nd Quarter = 8,400
3rd Quarter = 7,400
4th Quarter = 6,400

In addition, 6400 grams of raw materials inventory is on hand at the start of the 1st Quarter and the beginning accounts payable for the 1st Quarter is 3280. Each unit requires 8.40 grams of raw material that costs $1.40 per gram. Management desires to end each quarter with an inventory of raw materials equal to 30% of the following quarter's production needs. The desired ending inventory for the 4th Quarter is 8400 grams. Management plans to pay for 50% of raw material purchases in the quarter acquired and 50% in the following quarter. Each unit requires 0.30 direct labor-hours and direct laborers are paid $10.70 per hour.

1.Prepare the company's direct materials budget for the upcoming fiscal year (Round "Unit cost of raw materials" answers to 2 decimal places).
2.Prepare a schedule of expected cash disbursements for purchases of materials for the upcoming fiscal year.
3.Prepare the company's direct labor budget for the upcoming fiscal year, assuming that the direct labor workforce is adjusted each quarter to match the number of hours required to produce the forecasted number of units produced. (Round "Direct labor-hours per unit" and "Direct labor cost per hour" answers to 2 decimal places.)

1. Write a for loop that will display all of the multiples of 3, one per line.

The starting point is a variable called lower, and the ending point is an integer called upper, inclusive.

The "lower" and "upper" variables have been properly declared and assigned values where the value of lower is less than or equal to the value of upper. Declare any other variables that are needed.

2. Write a "while" loop that does the same thing as the following "for" loop.

for (i=6;i<1000;i+=5)

   cout<<i<<endl;

3. Write an if statement to print the message "The size is valid" if the variable named size is in the range 5 to 18, including 5 and 18. Otherwise print "The size is not valid".

Consider requirements gathering. Tell us 3 challenges of requirements engineering and project management. Why were they challenging?

You have been hired as a consultant for Pristine Urban-Tech Zither, Inc. (PUTZ), manufacturers of fine zithers. The market for zithers is growing quickly. The company bought some land three years ago for $1.38 million in anticipation of using it as a toxic waste dump site but has recently hired another company to handle all toxic materials. Based on a recent appraisal, the company believes it could sell the land for $1,480,000 on an aftertax basis. In four years, the land could be sold for $1,580,000 after taxes. The company also hired a marketing firm to analyze the zither market, at a cost of $123,000. An excerpt of the marketing report is as follows: The zither industry will have a rapid expansion in the next four years. With the brand name recognition that PUTZ brings to bear, we feel that the company will be able to sell 3,600, 4,500, 5,100, and 4,000 units each year for the next four years, respectively. Again, capitalizing on the name recognition of PUTZ, we feel that a premium price of $630 can be charged for each zither. Because zithers appear to be a fad, we feel at the end of the four-year period, sales should be discontinued. PUTZ feels that fixed costs for the project will be $415,000 per year, and variable costs are 15 percent of sales. The equipment necessary for production will cost $3.30 million and will be depreciated according to a three-year MACRS schedule. At the end of the project, the equipment can be scrapped for $390,000. Net working capital of $123,000 will be required immediately. PUTZ has a 40 percent tax rate, and the required return on the project is 13 percent. Assume the company has other profitable projects. MACRS schedule. What is the NPV of the project? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

To make telephone numbers easier to remember, some companies use letters to show their telephone number. For example, using letters, the telephone number 438-5626 can be shown as GET LOAN. In some cases, to make a telephone number meaningful, companies might use more than seven letters. For example, 225-5466 can be displayed as CALL HOME, which uses eight letter. Write a program that prompts the user to enter a telephone number expressed in letters and outputs the corresponding telephone number in digits. If the user enters more than seven letters, than process only the first seven letters. Also output the - (hyphen after the third digit. Allow the user to use both upper case and lowercase letters as well as spaces between words. moreover, your program should process as many telephone numbers as the user wants.

Desired Outputs:

Enter Y/y to convert a telephone number from letters to digits. Enter any other letter to terminate the program.

Define the difference between current and long term liabilities. Creditors use several measures to assess a company's creditworthiness, such as working capital, current ratio, payables turnover, and days' payable. Discuss what these measures are and why it's important to carefully measure cash flows related to current liabilities.

Discuss the tradeoffs between the following concepts:

• coordination and control
• centralization and decentralization
• Hierarchal vs. network and virtual organizational forms

A university has implemented a new enrollment system. The scenario below outlines the steps to enroll a new student in the university. Perform a system analysis based on the scenario and respond to the questions below. Note-some requirements might not be explicitly stated in the scenario. List all assumptions used for this analysis.

Scenario: Enroll new student in the University

1. An applicant wants to enroll in the university.
2. The applicant hands a filled-out copy of University Application Form to the registrar.
3. The registrar inspects the forms.
4. The registrar determines that the forms have been filled out properly.
5. The registrar clicks on the Create Student icon.
6. The system displays Create Student Screen.
7. The registrar inputs the name, address, and phone number of the applicant.
8. The system checks whether the applicant is on the applicants list and whether they already exist within the system.
9. If the student is on the applicants list but not already on the system, then a record is created.
10. The student enrolls in courses.
11. The system calculates the required initial payment.
12. The system displays Fee Summary Screen.
13. The student pays the initial fee.
14. The system prints a receipt.
15. The registrar validates and gives the student the receipt.
16. The process ends.

1. Discuss the stakeholders and users of the system and indicate how you would collect requirements from them
2. Identify the business, stakeholder, and solution requirements for the system.
3. Create a use case diagram to verify the functional requirements of this system.
4. Diagram the business workflow (process) for the system.
5. Using any analysis class technique(s), develop a high-level class diagram to validate the requirements and components of the problem domain.
