Income Tax The original U.S. income tax of 1913 was quite simple. The tax was: ● 1 percent on the first $50,000. ● 2 percent on the amount over $50,000 up to $75,000. ● 3 percent on the amount over $75,000 up to $100,000. ● 4 percent on the amount over $100,000 up to $250,000. ● 5 percent on the amount over $250,000 up to $500,000. ● 6 percent on the amount over $500,000. There was no separate schedule for single or married taxpayers. Write a program that computes the income tax according to this schedule.

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; }

Programming Exercise 10 in Chapter 6 asks you find the mean and standard deviation of five numbers. Extend this programming exercise to find the mean and standard deviation of up to 100 numbers. Suppose that the mean (average) of n numbers x1, x2, . . ., xn is x. Then the standard deviation of these numbers is:S=sqrt(((x1-x)^2+(x2-x)^2+...+(xi-x)^2+...+(xn-x)^2)/n)
python code Problem 5 A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 9. Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4 . Write a program that will make these calculations. Your program should use two separate functions to calculate fat and carb calories. Write a 3rd function that is called from main to capture user input and call the others.
Python Programming Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B and C = 2D, E and F = 3G, H and I = 4J, K and L = 5M, N and O = 6P, Q, R and S = 7T, U and V = 8W, X, Y and Z = 9 Write a program that asks the user to enter a 10-character number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if user enters 555-GET-FOOD, the application should display 555-438-3663. After displaying the translated telephone number, ask the user if they’d like to enter another number. If the user enters “y”, run program again. If not, terminate the program. Note: the sentence the program reads SHOULD NOT be hardcoded. Allow the user to enter the sentence the program reads
Computer Fundamentals and Programming 2 Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

Open notes and open book. Suppose you have a certain amount of money in a savings account that earnscompound monthly interest, and you want to calculate the amount that you willhave after a specific number of months. The formula is as follows:f = p * (1 + i)^t• f is the future value of the account after the specified time period.• p is the present value of the account.• i is the monthly interest rate.• t is the number of months.Write a program that takes the account's present value, monthly interest rate,and the number of months that the money will be left in the account as threeinputs from the user. The program should pass these values to a function thatreturns the future value of the account after the specified number of months.the program should print the account's future value.

(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:
When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)
19.16 LAB: Area of a triangle Using Heron's formula, you can calculate the area of a triangle if you know the lengths of all three sides. Given the length of each side of a triangle as input, calculate the area of the triangle using Heron's formula as follows: s = half of the triangle's perimeter area = the square root of s*(s-a)*(s-b)*(s-c), where a, b, and c are each sides of the triangle. Hint: Use the math function sqrt() for calculating the square root. Output the floating-point value of the area with two digits after the decimal point using the following statement once before all other cout statements:cout << fixed << setprecision(2); Ex: If the input for a, b, and c is: 3.0 4.0 5.0 the output is: Triangle area = 6.00 #include <iostream>#include <iomanip>#include <cmath>using namespace std; int main() { /* Type your code here. */ return 0;
