Write a superclass encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length; it has two methods that calculate and return its area and volume. You also need to include a client class to test these two classes.

You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???

Along with the encrypted copy, some mysterious person has also given you the following documents:

helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.

hints.txt -- Seems important.

In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:

decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")

Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).

Hint: The penny math lecture is here.

Another hint: Don't forget about while loops...

Mac hint: use encoding="utf-8" in your file open functions, like this:

Mac hint: use encoding="ascii" in your file open functions, like this:

fin = open(input_file,"r",encoding="ascii")

One view of intrusion detection systems is that they should be of value to an analyst trying to disprove that an intrusion has taken place. Insurance companies and lawyers, for example, would find such evidence invaluable in assessing liability. Consider the following scenario. A system has both classified and unclassified documents in it. Someone is accused of using a word processing program to save an unclassified copy of a classified document. Discuss if, and how, each of the three forms of intrusion detection mechanisms could be used to disprove this accusation.

What is one advantage of using the Option Group Control for data validation? It works best with fields that use the date data type. It alerts the user when the database is about to close. It applies to numeric fields only, eliminating text errors. The data entry is restricted to specific fields, reducing errors.

First, open two separate terminal connections to the same machine, so that you can easily run something in one window and the other. Now, in one window, run vmstat 1, which shows statistics about machine usage every second. Read the man page, the associated README, and any other information you need so that you can understand its output. Leave this window running vmstat for the rest of the exercises below. Now, we will run the program mem.c but with very little memory usage. This can be accomplished by typing ./mem 1 (which uses only 1 MB of memory). How do the CPU usage statistics change when running mem

Write a program that asks the user to enter their yearly income. The program should display the user's tax bracket according to the following guidelines: Income below $50,000: Tax Bracket 1 Income of $50,000 - $99,999.99: Tax Bracket 2 Income of $100,000 or above: Tax Bracket 3 The program should then output the amount of federal taxes they will have to pay given that the Federal Tax Rate is 15% (for all tax brackets).

20. When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2 / 12 5 0.6%. The first month’s interest on $1,000 is 1000 3 0.006 5 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 2 6 5 19. This means after making the first payment, the loan amount is 1, 000 2 19 5 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 3 0.006 5 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 2 5.89 5 19.11 and the remain- ing balance after the second payment is 981 2 19.11 5 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then out- puts the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first month’s interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)

28. (Apartment problem) A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit?

Write a program that prompts the user to enter:

a. The total number of units.

b. The rent to occupy all the units.

c. The increase in rent that results in a vacant unit.

d. Amount to maintain a rented unit.

The program then outputs the number of units to be rented to maximize the profit.

30. Let n be an integer. The value of the expression lim (1 1 1 ) is n→` n written as e. This number e appears in many places in mathematics. For example, it appears in the formula A 5 Pert to compute the total mount accumulated when the interest is compounded continuously. It also appears in problems relating to exponential growth and decay. It is known that e is an irrational number. The value of e to nine decimal places is e 5 2.718281827. Write a program that computes the value n of the expression lim (1 1 1 ) between certain values of n and then n→` n compare the values with e. For example, you can compute the values of the expression between 100 and 10,000 with an increment of 100, or between 1,000 and 1,000,000 with an increment of 1,000.
