Strings are used in virtually all scripts to either output text or input values from the user. This Discussion Board will explore the immutability of strings and how you could overcome this potential limitation when concatenating strings together. In the Discussion Board, reply to the following: Discuss what happens when strings are concatenated together within the computer's memory. Describe any ideas on how to make the concatenation process as fast as possible considering the immutability of strings.

Scenario Instructions You are a Mathematics major who has agreed to teach an elementary school math class where the students are studying geometry. They are just starting to learn about sine, cosine, and tangent. You've decided that you want to show the students what these functions look like when they have been graphed. Write a Python program to display three separate graphs for sin, cos, and tan. Add the ability to show all three graphs on a single graph with one row and three columns.

PYTHON CODE Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called "tickets.txt" and continue to loop your program asking...

X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false

Python Returning function function name: is_prime parameters: a number n returns: True if n is prime behavior: Check the values in the range [2, n) and return False if n is divible by any of them. function name: bound_0_to_100 parameters:a number grade returns: the grade with a minimum of 0 and a maximum of 100 behavior: In addition to exceeding 100, sometimes a grade will be so spectacularly bad that it falls below 0. In that case we want to normalize it to 0 so all grades fall into the range [0, 100]. ex: bound_0_to_100(75) returns 75, bound_0_to_100(103) returns 100, and bound_0_to_100(-5) returns 0 function name: bigger parameters: two values a and b returns: whichever of the two is greatest behavior: ex: bigger(3, 9) returns 9

The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed...
