Write a function that has a single input argument grade. If the user's input is a numeric number, the grade letter should be displayed to the command window depending on the value of grade, as shown in the table below. Otherwise, MATLAB should stop the execution and send an error message: "invalid input" to the command window. Grade Grade Letter Grade 2 90 A 90 > Grade > 80 В 80 > Grade 2 70 C 70 > Grade 2 60 60 > Grade Grade >100 or Unknown Grade < 0

Write a function called factorial that computes the factorial of a given number x passed in as an argument. By default it returns the factorial of 6, which is 720. It also takes a optional boolean argument called 'to_print'. If to_print is True, the factorial value is printed instead of being returned. It is False by default, meaning the result is returned, not printed. >>> result = factorial()>>> print(result)Output: 720>>> result = factorial(to_print = True)Output: 720>>> print(result) Output: # no output>>> result = factorial(4)>>> print(result) Output: 24>>> factorial(4, to_print = True)Output: 24>>> print(result) Output:

Here are three versions of a code fragment located inside a function: Version A for Row in range(10):       for Column in range(5):          DoSomethingInteresting(Row,Column)          return Version B for Row in range(10):      for Column in range(5):             DoSomethingInteresting(Row,Column)      return Version C for Row in range(10):      for Column in range(5):            DoSomethingInteresting(Row,Column) return   How many times do each of the versions call the DoSomethingInteresting function? Write a sentence or two explaining which version is the "correct" version

Written in C Please   Create a calculator program as follows.Create a menu function named kitten ( function should display the menu options and return the userselection with the following options. Prototype int kitten(void); ) :1 to calculate the number of real solutions for a quadratic equationPrototype: void fluffy(float a, float b, float c);2 to calculate the resistance in series for two or more resistors (no limit on number of resistors)Prototype: float series(float a, float b);3 to calculate the resistance in parallel for two or more resistors (no limit on number of resistors)Prototype: float parallel(float a, float b);4 to calculate the total of raising a value to an integer power value.Prototype float frisky(float x, int y);5 to exit programRepeatedly display the menu after each calculation until option 5 is entered.YOU HAVE TO CREATE AND USE ALL FIVE FUNCTIONS.Option 1:Ask the user for and store the three numerical coefficients of a quadratic equation and store them inthree…
