Chapter 2, Problem 2.13PE
(Financial application: compound value) Suppose you save $100 each month into a savings account with an annual interest rate 5%. Thus, the monthly interest rate is 0.05/12 = 0.00417. After the first month, the value in the account becomes
100 * (1 + 0.00417) = 100.417
After the second month, the value in the account becomes
(100 + 100.417) * (1 + 0.00417) = 201.252
After the third month, the value in the account becomes
(100 + 201.252) * (1 + 0.00417) = 302.507

Problem Description:
In the Whimsical Library, each book is enchanted with a magical code to ensure the
protection of knowledge. The validation process for these magical codes involves a
combination of mathematical spells.
The validation process is described as follows:
Take the sum of the digits at odd positions from left to right.
Take the sum of the squared digits at even positions from left to right.
If the absolute difference between the results from step 1 and step 2 is a prime
number, the book code is considered valid; otherwise, it is invalid.
Example 1:
Consider the magical book code 86420137.
Step 1. Take the sum of the digits at odd positions from left to right.
8+4+0+3=15
Step 2. Take the sum of the squared digits at even positions from left to right.
6^2+2^2+1^2+7^2=36+4+1+49 = 90
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
115-901 = 75 (not a prime number)
Book code 86420137 is invalid.

- (Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game. Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock. The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.arrow_forward4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice. TarningsKast2 How many dices do you want to throw? 11 Which number do you want the probability for?

Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation. - -arrow_forward

Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output.

E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000". E.g., lottery = 123, input = 321(3) If two digits in the user input matches a digit in the lottery, print "the award is $3,000". E.g., lottery = 123, input = 612(4) If one digit in the user input matches a digit in the lottery, print "the award is $1,000".

- Q2: (Financial: Compare cost) Suppose you shop for rice in two different packages. You would like to write a program to compare the cost. The program prompts the user to enter the weight and price of each package and displays the one with the better price. Here is a sample run: Enter weight and price for package 1: 50 24.59 Enter weight and price for package 2: 25 11.99 Package 2 has a better price.arrow_forwardProgram - python A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 9. Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4. Write a program that will make these calculations. Your program should use two separate functions to calculate fat and carb calories. Write a 3rd function that is called from main to capture user input and call the others.arrow_forwardFilling the Pool (Deprecated) Write a program that calculates the time neccessary to completely fill an empty pool with water. We will assume that the pool is rectangular and the depth is uniform. All input values in this program will be integers. Prompt the user to enter the pool dimensions - length, width, and depth (unit: feet) - as well as the rate at which water can be put into the pool (unit: gallons per minute). Using these values, calculate and display the time (in minutes) needed to fill the pool from completely empty to completely full. Note: you should calculate the volume of the pool (as cubic feet) and then determine the rate (in cubic feet per minute) that water can be put into the pool. Assume that there are 7.48 gallons in one cubic foot. Your program should run like the examples shown below: Enter pool dimensions Length: 10 Width: 8 Depth: 7 Water entry rate: 14 The pool will fill completely in 299.2 minutesarrow_forward
