6.Engineers often measure the ratio of two power measurements in decibels, or dB, which can be calculated as follows: dB = log10 P₂ P₁ Where P2 is the power level being measured, and P₁ is some reference power level. Write a function that calculates the level. The function's prototype is as follows: double dBCalculator (double P1, double P2); Then, call dBCalculator from the main function to find the power ratio for the measurements from 1 to 20 Watts, in 0.5 Watt steps. You can assume that the reference power is 1 Watt.
Assume there is a function called mystery. It already has the following prototype: void mystery(bool flag); Which of the following prototypes would not be considered a proper overload for mystery? void mystery(bool valid); void mystery(string msg, double x); void mystery(int num); void mysteryO:
Write a function call to ConvertVolume() to store the number of quarts, pints, and ounces within the integer variables numQuarts, numPints, and numOunces, respectively.

Consider the function definition below. Assume x = 5, y = 3 and j = 8 as the function starts. Which variables will change after the function finishes? void findout (int &x, int y, int &j) { for (int i = 1; i 5) { x = 2*x - 3*y; y = 4 + 3 x; } else { Oi y = 2*x - 3; x = 4 + 3% y; } } // end of for loop x and y y All three since the first and last are references. x and j
INSTRUCTIONS: Write a C++ script/code to do the given problems.MOVIE PROBLEM: Write a function that checks whether a person can watch an R18+ rated movie. One of the following two conditions is required for admittance:• The person is atleast 18 years old.• They have parental supervision.The function accepts two parameters, age and isSupervised. Return a boolean. Let the age and if supervised (yes or no) be user-input.Example:acceptIntoMovie(14, true) ➞ trueacceptIntoMovie(14, false) ➞ false

Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])

O d. The actual parameters are defined in the header of a function; for example, in the following function the actual parameters are x and y: def f(x,y): The formal parameters are those provided to a function at the time the function is called; for example, 5 and 15 are the formal parameters of the function f: k f(5,15) Ое. The formal parameters are defined in the header of a function; for example, in the following function the formal parameters are 5 and 15: def f(5,15): The actual parameters are those provided to a function at the time the function is called; for example, x and y are the actual parameters of the function f: k f(x,y) %D
