In the U.S. fuel efficiency of cars is specified in miles per gallon (mpg). In Europe it is often expressed in liters per 100 km. Write a MATLAB user- defined function that converts fuel efficiency from mpg to liters per 100 km. For the function name and arguments, use Lkm=mpgToLpkm (mpg). The input argument mpg is the efficiency in mi/gl, and the output argument Lkm is the efficiency in liters per 100 km (rounded to the nearest hundredth). Use the function in the Command Window to: (a) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 21 mi/gal. (b) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 36 mi/gal.

Write a function averageDigits that computes the average of the digits of a 3-digit positive number in the range [100,999), Use the following function prototype: double averageDigits(int); For example, averageDigits(936) returns 6.0 ((9+3+6)/3). Write a test program that prompts the user to enter a 3-digit number, call the function averageDigits and print the result in the main program. The process is repeated if the user enters y to continue.

Define a function calc_total_inches, with parameters num_feet and num_inches, that returns the total number of inches. Note: There are 12 inches in a foot.Sample output with inputs: 5 8 Total inches: 68

I am facing some issues with this c++ question. any help would be appreciated.

Write a function that receives a positive integer n as a parameter, then it must calculate the sum 1+2+3+...+n. Finally return the result of the sum and in the main function print that result to the screen. The output of the program should be just the value of the sum. Look at the example. Input: A positive integer n Output: The result of the addition 1+2+3...+n Program execution example: Entry 6 Departure twenty-one Entry 5Output fifteen Entry 7 Departure 28

For parameter passing, call by constant reference is for the function if the value of the actual parameter isn't changed and does no copying.  Group of answer choices True False

Write a function driving_cost() with input parameters miles_per_gallon, dollars_per_gallon, and miles_driven, that returns the dollar cost to drive those miles. All items are of type float. The function called with arguments (20.0, 3.1599, 50.0) returns 7.89975. Define that function in a program whose inputs are the car's miles per gallon and the price of gas in dollars per gallon (both float). Output the gas cost for 10 miles, 50 miles, and 400 miles, by calling your driving_cost() function three times. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f {your_value:.2f}') Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call a function: def driving_cost (miles_per_gallon, dollars_per_gallon, miles_driven) 461710.3116374.qx3zqy7 LAB ACTIVITY 7.9.1: LAB: Driving costs - functions L23456 Define your function here. 4# Type your code here. main.py 0/10 Load default template...

Please answer it in Python Write a function division_arrondi that takes as an argument a numerator, a denominator, and as optional arguments a rounded Boolean  (worth False by default) and a decimal integer  (valid 0 by default) and that calculates the value of the numerator/denominator fraction (unless the denominator is zero, in which case your function will display an error message and return nothing). If the rounded Boolean is False, the function will return this result without rounding it (if decimales is specified during the call, it will be ignored). If the rounded Boolean  is True, the result will be rounded to the requested number of decimal places (by default, to the nearest integer). To make your rounds, you will use round(nombre_a_arrondir, nombre_de_decimales). Examples:division_arrondi(1,3) is 0.333333333333333333 division_arrondi(1,3,rounded=True, decimales=2) is 0.33 division_arrondi(15,8) is 1,875 division_arrondi(15,8, True) is 2 division_arrondi(15,8, rounded=True,…
