1- Write a MATLAB program to create a user-defined function to calculate the area of rectangle. Use the following formula: A = L*W.

please code in python 1).  Multiplication using Addition Write a function: mul(a,b) that will compute and return the product of two positive integers a and b using only a for loop and the addition operator ( + ).    Then, write a new function mul2(a,b) that does the same thing, but uses a while loop rather than a for loop.     2).  Exponentiation using Multiplication Write a function expo(x,y) that computes and returns the exponent xy using only a loop and the multiplication operator.   Then, adjust it so that rather than using the multiplication operator, it uses one of the multiplication functions you wrote in part 1.   Hints: xy is equal to (x * x * x * x ... x), y times. When you’re computing a sum using a loop, you start at 0, since anything + 0 is itself. When you’re computing a product using a loop, you start at ?, since anything * ? is itself (fill in the ?). If you wrote your mul function from part 1 correctly, then the following two lines should have the same effect, so you…

Write a function that takes as input a positive integer and returns true if it is prime and false otherwise. (C++)

Redo the program given where you have to define and use the following functions: (a) isTriangle - takes 3 sides of a triangle and returns true if they form a triangle, false otherwise. (b) isIsosceles - takes 3 sides of a triangle and returns true if they form an isosceles triangle, false otherwise. (c) isEquilateral - takes 3 sides of a triangle and returns true if they form anequilateral triangle, false otherwise. (d) isRight - takes 3 sides of a triangle and returns true if they form a right triangle, false otherwise. (e) your program should run continuous until the user wants to quit The given program: #include <iostream> #include <cmath> using namespace std; // Constant Declarations const double E = .0001; int main() { double side1, side2, side3; bool isTriangle, isRight, isEquilateral, isIsosceles; cout << "Enter the lengths of the 3 sides of a triangle -- "; cin >> side1 >> side2 >> side3; isTriangle = side1 + side2 > side3 &&side1…
