2.26 LAB: Expression for calories burned during workout 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 by executing cout << fixed << setprecision (2); once before all other cout statements. Ex: If the input is: 49 155 148 60 the output is: Calories: 736.21 calories

6.26 LAB: Exact change - functions Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimes Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies. def exact_change(user_total) Use Python, please.
4.18 C++ Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. End with a newline. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.
21.7 LAB: Login name (Use python) Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: JordaM91 Ex: If the input is: Kanye West 2024 the output is: Your login name: WestK24
C++ Question, Write a Computer Code: Let l be a line in the x-y plane. If l is a vertical line, its equation is x = a for some real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀). If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁).

1.Write program to iteratively compute Fibonacci numbers (named after an Italian mathematician).Some Fibonacci numbers are 1, 1, 2, 3, 5, 8, ... where the next number is found by summing the preceding two numbers. Your program will read in a number, like 7, report the first 7 numbers. in this case1,1,2,3,5,8,13. Your program is not assured of receiving good data, thus if -2 is received as the number of numbers, then an error should be reported.
7.24 LAB: Convert to binary-functions Write a program that takes in a positive integer as input, and outputs a string of 1's and O's representing the integer in binary. For an integer x, the algorithm is As long as x is greater than 0 Output x 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string Ex: If the input is the output is: 110 The program must define and call the following two functions. Define a function named int to reverse_binary() that takes an integer as a parameter and returns a string of 1's and O's representing the integer in binary (in reverse). Define a function named string reverse() that takes an input string as a parameter and returns a string representing the input string in reverse. def int_to_reverse_binary(integer_value) def string reverse(input_string) LAB ACTIVITY 7.24.1: LAB.

4.19 C++ Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Done", "done", or "d" for the line of text. Ex: If the input is: Hello there Hey done then the output is: ereht olleH yeH
5.28 LAB: Convert to binary - functions Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The IntegerToReverseBinary() function should return a string of 1's and 0's representing the integer in binary (in reverse). The ReverseString() function should return a string representing the input string in reverse. string IntegerToReverseBinary(int integerValue)string ReverseString(string userString)
10.25 LAB: Quadratic formula Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50

Ex: If the input is: 0 (or less than 0), the output is: No change Ex: If the input is: 45 the output is: 1 Quarter 2 Dimes Python for this please.
Python 3.7.4: The current calendar, called the Gregorian calendar, was introduced in 1582. Every year divisible by four was created to be a leap year, with the exception of the years ending in 00 (that is, those divisible by 100) and not divisible by 400. For instance, the years 1600 and 2000 are leap years, but 1700, 1800, and 1900 are not. Write a program that requests a year as input and states whether it is a leap year. We need to run this as many times as the user wants to check for leap years. --------------------------- Below is my original program. I need to change it so that it now has a main() function plus three more functions. Do I convert the while loop to an if loop? The instructor said that it was a bad habit to include "break" in loops, so I was able to eliminate that. I just don't know how I can get that many functions out of this program. ''' Determine if a given year is a leap year, running as many times as the user wants to check for leap years''' #…
