(Algebra: 2 × 2linear equations) Design a class named LinearEquation for a 2 × 2 system of linear equations:
The class contains:
- Private data fields a , b, c, d, e , and f .
- A constructor with the arguments for a, b, c, d, e , and f .
- Six getter methods for a , b, c, d, e, and f .
- A method named isSolvable () that returns true if ad - be is not 0.
- Methods getX () and getY () that return the solution for the equation.
Draw the UML diagram for the class then implement the class. Write a test program that prompts the user to enter a , b, c, d, e , and f and displays the result. If ad − bc is 0, report that “The equation has no solution.” See

- (Q1)This is a Data Structures problem and the programming language used is Lisp. Solve the question we detailed steps and make it concise and easy to understand. Please and thank you.arrow_forwardDiscuss the difference between void pointer and null pointer with examplearrow_forward7. Recursive Power Method In Python, design a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised, and the exponent. Assume the exponent is a nonnegative integer.arrow_forward
- Define variable arrayarrow_forwardJournal Bearing Properties Code Write a Matlab program code to determine the properties of the journal bearing and heat dissipation. You need to convert all charts and tables of the journal bearing properties from the textbook into a curve fit equation. The code must include the four cases of the length- diameter ratio (L/d) and the interpolation equation for a different L/d ratio. Test your code by solving Problem 12.11 from the textbook and compare the results with hand calculation. A full formal report must be submitted include all the curve fit equation for all charts and tables, sample calculations and the printed Matlab code with the results. A soft copy of the program code is required as well.arrow_forwardComputer Science need help plzarrow_forward

Question: Develop a polymorphic banking program using the Account hierarchy in which two types of Accounts can be created i.e.Current Account and Saving Account respectively. Each account must have to give the interest to the bank depending upon their account type. A function of name InterestRate() will calculate the interest of account and returns the interest amount. Current Account has annual interest rate of 0.1% of actual amount and SavingAccount will have to pay interest rate of 1.0% of actual amount. Also write a main function for polymorphic calls of the functions. Note: Polymorphic calls for the functions are necessary. Necessary constructor, Destructors, setters, getters and other functions should also be defined.arrow_forwardC++ Using Card and Deck class created during the lecture or your own implementation that follows the spec for a card and deck, implement the following game: game is designed for a single player who is playing against the computeryou draw three cards for each player (player and a computer) Using the compare function from the Card class you compare each pair drawnIf the player's card is higher, the player gets a pointYou repeat this comparison 3 times (for each pair of cards you draw)The player wins if he gets more points than a computer (has more higher cards than the computer)arrow_forward
- Python program (recursive function) A recursive function is a function defined in terms of itself via self-referential expressions. This means that the function will continue to call itself and repeat its behavior until some condition is met to return a result. Write a python recursive functionprod that takes x as an argument, and returns the result where, result=1*1/2*1/3*….*1/n Include a screenshot that shows a python program that uses the above function and prints the rounded result to three decimal placesafter prompting the user to enter a number, x. Use x=3. N.B: The code should be included please.arrow_forwardMULTIPLE FUNCTIONS AND RECURSIVE FUNCTIONS .arrow_forwardWhat is a recursive function?
