Chapter 6, Problem 15PC
Population
In a population, the birth rate is the percentage increase of the population due to births, and the death rate is the percentage decrease of the population due to deaths. Write a
- The starting size of a population (minimum 2)
- The annual birth rate
- The annual death rate
- The number of years to display (minimum 1)
The program should then display the starting population and the projected population at the end of each year. It should use a function that calculates and returns the projected new size of the population after a year. The formula is
- N is the new population size,
- P is the previous population size,
- B is the birth rate,
- and D is the death rate.
Annual birth rate and death rate are the typical number of births and deaths in a year per 1,000 people, expressed as a decimal. So, for example, if there are normally about 32 births and 26 deaths per 1,000 people in a given population, the birth rate would be .032 and the death rate would be .026.

b - Falling Distance When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period:
d = 1/2 gt2
The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling. Write a function named fallingDistance that accepts an object’s falling time (in seconds) as an argument. The function should return the distance, in meters, that the object has fallen during that time interval. Write a program that demonstrates the function by calling it in a loop that passes the values 1 through 10 as arguments and displays the return valuein c++ code

Function Name: leapYear Parameters: year – an nonnegative integer representing the year Test Cases: >>>leapYear(1996) The year 1996 is a leap year. Enjoy your extra day! >>>leapYear(1901) The year 1901 is not a leap year. Description: Write a function which calculates whether or not a given year is a leap year and has 366 days instead of 365. A general algorithm is as follows: 1. A year will be a leap year if it is divisible by 4 but not by 100. 2. If a year is divisible by 4 and by 100, it is not a leap year unless it is also divisible by 400. Years such as 1996, 1992, 1988 and so on are leap years because they are divisible by 4 but not by 100. For century years, the 400 rule is important. Century years (ex: 1900, 1800, 1700) are exactly divisible by 4 AND exactly divisible by 100. They are not divisible by 400 and are thus not leap years. You fuction should print out "The year XXXX is a leap year. Enjoy your extra day!" if the year XXXX is a leap year. Print "The…

- 4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward(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.arrow_forward(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation.

- (Statics) A beam’s second moment of inertia, also known as its area moment of inertia, is used to determine its resistance to bending and deflection. For a rectangular beam (see Figure 6.6), the second moment of inertia is given by this formula: Ibh3/12 I is the second moment of inertia (m4). b is the base (m). h is the height (m). a. Using this formula, write a function called beamMoment() that accepts two double- precision numbers as parameters (one for the base and one for the height), calculates the corresponding second moment of inertia, and displays the result. b.

Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a program that uses this method to calculate a contestant's score. It should include the following functions: void getJudgeData() should ask the user for a judge's score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five judges. void calcScore() should calculate and display the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the five scores. The last two functions, described below, should be called by calcScore, which uses the returned information to determine which of the…arrow_forward
- 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.

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.

The following formula can be used to determine a moving object’s kinetic energy:KE=12mv2The variables in the formula are as follows: KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Write a function named kinetic_energy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The function should return the amount of kinetic energy that the object has. Write a program that asks the user to enter values for mass andvelocity, then calls the kinetic_energy function to get the object’s kinetic energy.arrow_forward
