5. M Mrs. Keller had 55.4 inches of rain in her rain gage during Hurricane Harvey approximation that is used sometimes is that 1 inch of rain is equal to 6.45 inches of snow. Write a user-defined function called An LastName_FirstName_Exam_Rain2Snow that does this conversion. Then write a script file that calculates and displays how much snow Mrs. Keller would have had at her home, had Hurricane Harvey produced snow. Finally, ask the user to input 3 different values for inches of rain and display both the input and output. Your input should be checked for legitimate values [i.e. it should be positive]. Users should enter 3 different values before any calculations are done. Run your program several times to show that the user input checks are working and copy the results to the program. 6. Given the following matrices
