Given caffeine amount (in mg) as input, outputthe caffeine level after 6, 12, and 24 hours. Use a string formatting expression with conversionspecifiers to output the caffeine amount as floating-point numbers.Output each floating-point value with two digits after the decimal point, which can be achieved asfollows:print('{:.2f}'.format(your_value))Ex: If the input is:100the output is:After 6 hours: 50.00 mgAfter 12 hours: 25.00 mgAfter 24 hours: 6.25 mgNote: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer)has between 100 mg and 200 mg.312198.2042412.qx3zqy7LAB9.14.1: LAB: Input and formatted output: Caffeine levels0/ 10ACTIVITYmain.pyLoad default template...1 caffeine_mg = float(input())

6.23 LAB: Leap year - functions A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 is a leap year. Ex: If the input is: 1913 the output is: 1913 is not a leap year. Your program must define and call the following function. The function should return True if the input year is a leap year or False otherwise.def is_leap_year(user_year) Use Python, please.
3.34 LAB: Mad Lib - loops in C++Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and integer as input, and outputs a sentence using those items as below. The program repeats until the input is quit 0. Ex: If the input is:apples 5shoes 2quit 0 the output is:Eating 5 apples a day keeps the doctor away.Eating 2 shoes a day keeps the doctor away. Make sure your answer is in C++.
7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. 311 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. The formula for computing the area of a pentagon is Area 3√3 2 -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5' where r is the length from the center of a pentagon to a vertex. Here is a sample run: Enter the length from the center to a vertex: 5.5 Enter The area of the pentagon is 108.61
6.19 LAB: Leap year - functions A common year in the modern Gregorian Calendar consists of 365 days. In reality, Earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days. An extra day, February 29th. The requirements for a given year to be a leap year are 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400, therefore, both 1700 and 1800 are not leap years Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines the number of days in February for that year Ex. If the input is 1712 the output is 1712 has 29 days in February. Ex If the input is 1913 the output is 1913 has 28 days in February. Your program must define and call the following function. The function should return the number of days in February for the input year. def days in feb(user_year)
4.16 LAB: Interstate highway numbers Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: I-90 is primary, going east/west. Ex: If the input is: 290 the output is: I-290 is auxiliary, serving I-90, going east/west. Ex: If the input is: 0 the output is: 0 is not a valid interstate highway number. Ex: If the input is: 200 the output is: 200 is not a valid interstate highway number. See Wikipedia for more info on highway numbering. 344614.2153518.qx3zqy7 Use Python. Don't use Java cause that's…

Q2) (Perfect Numbers) An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 = 1 + 2 + 3. Write a function perfect that determines if parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect. Challenge the power of your computer by testing numbers much larger than 1000.
