The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article (source): Calories = ( (Age x 0.2757) + (Weight x 0.03295) + (Heart Rate x 1.0781) — 75.4991 ) x Time / 8.368 Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output the average calories burned for a person. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'Calories: {calories:.2f} calories')
Justin receives 52 weekly paychecks per year. Each week, he contributes a specific percentage of his gross weekly pay to his retirement plan at work. His employer also contributes to his retirement plan, but at a different rate. Justin wants a program that calculates and displays the total annual contribution made to his retirement plan by him and his employer. Desk-check your solution’s algorithm using $640 as the gross weekly pay, 6% as Justin’s contribution rate, and 4% as the employer’s contribution rate. Then desk-check it using your own set of data.

[Python Language] A common back-of-the-envelope technique for estimating a runner’s marathon time is to take their best half-marathon time, multiply by two and add ten minutes. This works pretty well unless the marathon course is hilly.If it is hilly, we add an extra 20 minutes to the estimate. Write a program that takes two lines of input: a float giving the half- marathon time in minutes and an integer indicating whether the marathon course is hilly(1) or not (0). It prints a float giving the estimated number of minutes the runner will take to run the full marathon. Write your pro- gram in a file named marathon.py.
On Thursday, November 4, 2021, Big Man Games wrote: Computer programs are great at computing mathematical formulas. Once the formula is properly encoded you can use the code as much as you want without reprogramming it and you can share it with non-programmers without any trouble. This lab is an example of such a formula. Once you program it you won’t have to worry about the area of a circle again. Write and test a program that computes the area of a circle. This program should request a number representing a radius as input from the user. Use the formula 3.14 × radius2 to compute the area. Tip: There are a couple of ways to code an exponent. Look in the Operators unit for help (and you can’t use an x for multiplication). Tip: You will need to use the float data type to compute the remainder. The output should explain the results. Don’t just print a number. Tip: For your print statement you will need to use the comma, “,”, or plus, “+” symbols to stitch your output together. (“The…
Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. 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 program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
I am writing a program that calculates the are of a triangle using the following formula: Area = (a2/2) * [sin α1 * sin αmgle2)/sin(αngle1 + αngle2). I am having issues with the angles because the angles need to always be greater than 0 and the sum of the 2 angles need to always be less than 180. Also, the area can't be a negative number. I almost got it down, but of course with an if statement nothing will print in the terminal if the conditions aren't meet. I've tried with a while loop, but was unsuccessful with that. What can I do so that this condition if(my_rank != 0 && alpha1 >= 1 && alpha2 >= 1 && alpha1 + alpha2 < 180) is always met? int a;int b;float c;bool m = false;alpha1 = rand()%180;alpha2 = rand()%180;baseA= (((float)rand()/(float)(RAND_MAX)) * 11 + 10) + ((float)rand()/(float)(RAND_MAX)); if(my_rank != 0 && alpha1 >= 1 && alpha2 >= 1 && alpha1 + alpha2 < 180){m = true;MPI_Send(&alpha1, 1, MPI_FLOAT, 0,…
6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.
Write a program that calculates and prints the volume of a pyramid given the base (b) and the height (h) of the pyramid. The formula to calculate the volume is: Volume = (1/3) *b * h Enter the base of the pyramid: 3 Enter the height of the pyramid: 2 The volume is 1.9998
Given an airplane's acceleration and take-off speed v, you can compute the minimum runway length needed for an airplane to take off using the following formula. length=v^2/2*a. write a program that prompts the user to enter V in meters and acceleration an in meter/second and display the minimum runway length.
quadratic.py by using "sys.argv" ● Create a program, quadratic.py, that takes in three arguments that represent the a, b, and c values in the quadratic formula. The values should be to two decimal places. You do not need to account for imaginary values. Then print out both roots in the form: “The solutions are x and y” Where x and y correspond to the positive and negative roots, respectively.
