Situation:Conduct a survey for investigatory project to ask how satisfied the students are with the current state of our school. Use a rating system of 1 to 10. There are a lot of people who answered the survey and you could not accurately tally the number of people who answered 1, or 10, or any other number in between.
Tracking laps
Learning Objectives
In this lab, you will practice
writing functions, passing arguments and returning results from the function
printing the result of a function call
writing your code as a module
Instructions
Main Idea
An Olympic-size swimming pool is used in the Olympic Games, where the racecourse is 50 meters (164.0 ft) in length. "In swimming, a lap is the same as a length. By definition, a lap means a complete trip around a race track, in swimming, the pool is the race track. Therefore if you swim from one end to the other, you’ve completed the track and thus you’ve completed one lap or one length." (Source: What Is A Lap In Swimming? Lap Vs Length)
Write the function meters_to_laps() that takes a number of meters as an argument and returns the real number of laps. Complete the program to output the number of laps with two digits after the period.
Examples
Input:
150
Output :
3.00
Input:
80
Output:
1.60
Your program must define and call the following…
Context
You work with the team in charge of the automatic driving program at Tesla. You are in charge of programming the necessary braking to be applied in the event that the car's on-board computer detects a stationary obstacle that appears directly in front of the car.
Constraints
In order not to rush the passengers of the car too much, the program would like to brake as gently as possible.
To keep a certain safety margin, the program must stop 1 meter before reaching the obstacle.
Modelization
Start by modeling the acceleration required to bring the car to a complete stop (while respecting the constraints) as a function of the speed at which the car was initially traveling and the distance at which the obstacle appeared.
Then test your model by calculating the modulus of the acceleration needed for the following values
The car was traveling at 45 km/h;
The obstacle appeared 23 meters in front of the car;

- Hospital Management Project "Simple Scenario We want to develop a comprehensive software product for XY Hospital, where several doctors are working together. There are several departments in the hospital, but a central administrationoffice is handling the patient appointment tasks. Most patients make an appointment before their visit. However, patients can walk in and can be treated if an appropriate doctor is available. On events, patients may change their visit schedule by calling. A patient who made an appointment but cannot appear should cancel his/her appointment in order to avoid a "no-show penalty. The appointment clerks i the administration office are handling all the appointments and the scheduling clerks generate "daily treatment schedules for doctors based on the appointment. The "daily treatment schedules' include doctor's name, patient's information, nurses and treatment rooms for each treatment.

Programming exercise 6 in Chapter 2 was the Sales Tax program. For that exercise you were asked to design a program that calculates and displays the county and state sales tax on a purchase. If you have alreday designed that program, refactor it so the subtasks are in modules. If you have not alreday designed that program, create a modular design for it. My problem is that we did not do the previous question stated in this example. I am unsure of even where to start on how to make this modular code. We are using Python for our coding source.arrow_forward

- THIS NEEDS TO BE DONE IN C#! Instructions For your first task as a newly formed team of developers, you will design, develop, test, and deliver a small software application to a client. You will first take the requirements for the project and implement a UML and function design for each of the classes you need to create. This MUST be achieved first. You will need to read and understand the requirements and choose good classes that need to be created in the development phase of this project. After you are finished with the design, you will use Visual Studio, C#, and GitHub to develop and test the project. Teams will need to determine who will write what parts of the system before development proceeds. Members will need to create branches to work in, which should be used to work in. Commits should be made often and contain details on changes made in the code. Once intended work for a branch is made, a pull request should be made to its parent branch to merge work.
