(General math) a. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The subroutine should determine and return the hypotenuse, c, of the triangle. (Hint:UsePythagorastheorem,c2=a2+b2.) b. Include the function written for Exercise 4a in a working program. The main() function should call rightTriangle() correctly and display the value the function returns.
(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:
Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
(Misc. application) a. The data in the following chart was collected on a recent automobile trip: Write a C++ program that accepts a mileage and gallons value and calculates the miles pergallon (mpg) for that segment of the trip. The mpg is obtained as the difference in mileage between fill-ups divided by the number of gallons of gasoline used in the fill-up. b. Modify the program written for Exercise 9a to also compute and display the cumulative mpg after each fill-up. The cumulative mpg is calculated as the difference between the mileage at each fill-up and the mileage at the start of the trip divided by the sum of gallons used to that point in the trip.
Test Average and Grade Write a program that asks the user to enter five test scores. The program should display a letter grade for each score and the average test score. Write the following functions in the program: calc_average. This function should accept five test scores as arguments and return the average of the scores. determine_grade. This function should accept a test score as an argument and return a letter grade for the score based on the following grading scale: Score Letter Grade 90–100 A 80–89 B 70–79 C 60–69 D Below 60 F Write the following functions: getTestScore(): This function prompts user for five test scores and returns test score to the caller. calcAverage(): This function accepts five test scores as arguments and returns the average of the five test scores. determineGrade(): This function accepts an average as an argument and returns a letter grade for the score based on the grading scale. displayData(): This method displays all five…
3. [fight_song.py] Write a program that outputs the following fight song. Your program is required to have a function named `sing_fight_song`. When the `sing_fight_song` function is called it should "sing" the song below by printing it out. You should create other functions to show structure and to eliminate redundancy in your program. More precisely, your `sing_fight_song` function should not consist solely of print statements printing each line of the song. That would be highly redundant. It should call other functions that print reusable parts of the song. Go, team, go! Defeat your foe. Go, team, go! Defeat your foe. Simply the best, Better than the rest. Go, team, go! Defeat your foe. Go, team, go! Defeat your foe. Simply the best, Better than the rest. Go, team, go! Defeat your foe. Go, team, go! Defeat your foe.
Future Investment Value = investment amount * (1 + monthly interest)^(number of years * 12) Using this formula, write a function in Python called futureValue that prompts the user to enter an investment amount, an annual percentage interest rate, and the amount of years. The function should accept the input as arguments. The interest rate should have a default value of 7%. You can add default values of your choice for the amount of years. This function should print out a table that displays the future values. Demonstrate this function in another function called main. Format your output by two decimal places. Output Example: Enter the amount you want to invest: 1000 [Enter] Enter the interest rate for your investment: [Enter] Enter the number of years you want to invest this money: 30 [Enter] Years Future Value 1 1093.81 2 1196.41 ........ 30 14730.58
One foot equals 12 inches. Write a function, using python, named feet_to_inches that accepts a number of feet as an argument and returns the number of inches in that many feet. Use the function in a programs, using python, that prompts the user to enter a number of feet then displays the number of inches in that many feet.

A bank charges $10 per month, plus the following check fees for a commercial checking account: $0.10 each for less than 20 checks $0.08 each for 20 through 39 checks $0.06 each for 40 through 59 checks $0.04 each for 60 or more checks Write a function BankCharges() that allows the user to enter the number of checks written and computes and displays the bank’s service fees for the month. All checks for the month are assigned the same charge, based on the total number of checks written during the month. Use the following test data to determine whether the application is calculating properly. In each case, the customer is charged only a single rate, based on the total number of checks. Your solution should clearly show the function. Customer Number of Checks Bank Charges Nancy 15 Lilian 25 Arianna 45 Ben 75
