Complete the following in syntactically correct Python code.

Write a program, using a for loop, that calculates the amount of money a person would earn over a period of time if his or her salary is 1 penny for the first day, 2 pennies for the second day, 4 pennies for the third day, and continues to double each day.

1.      The program should ask the user for the number of days the employee worked.

2.      Display a table showing the salary for each day.

3.      Display the total salary at the end of the period.

4.      The output should be displayed in dollar amounts, not the number of pennies.

5.      Format your output to include a $ sign and 2 decimal places.

6.      Be sure to comment appropriately.

Inventory Management

Your company keeps fleets of vehicles at a number of sites around the country. At each site the vehicles can be classified into two types: light and heavy. A heavy vehicle costs more per day, but it can do any task that a light vehicle can do. You would like to determine what mix of vehicles your company should have at each site. If you do not have enough vehicles of the appropriate size to meet the demand on a given day, you must rent the vehicles. Some cost data were collected on the cost of various vehicle types:

Vehicle Type             Daily fixed cost          Daily variable cost (if used)

Owned Light               $32                              $40

Owned Heavy                         $44                              $54

Rented Light               0                                  $175

Rented Heavy             0                                 $225

At a particular site, your company collected demand data for the number of vehicles required on each of seven days:

Day     Lights             Heavies

1          6                      0

2          3                      2

3          5                      4

4          8                      3

5          2                      1

6          4                      4

7          1                      2

Based on just the above data, what is your recommendation for the number of vehicles to own of each type at this site? What is your weekly cost?

class is not templated

You need to write a class called LinkedList that implements the following List operations:

public void add(int index, Object item);
// adds an item to the list at the given index, that index may be at start, end or after or before the

// specific element

2.public void remove(int index);

// removes the item from the list that has the given index

3.public void remove(Object item);

// finds the item from list and removes that item from the list

4.public List duplicate();

// creates a duplicate of the list

// postcondition: returns a copy of the linked list

5.public List duplicateReversed();

// creates a duplicate of the list with the nodes in reverse order

// postcondition: returns a copy of the linked list with the nodes in

6.public List ReverseDisplay();

//print list in reverse order

7.public Delete_Smallest();

// Delete smallest element from linked list

8.public List Delete_duplicate();

// Delete duplicate elements from a given linked list.Retain the earliest entries.

9 Make a function that adds a linked list to itself at the end.

Input:

4 -> 2 -> 1 -> NULL

Output:

4 -> 2 -> 1 -> 4 -> 2 -> 1 -> NULL

note : code should work on Visual studio 2017 and provide screenshot of output

For this exercise, you will implement two programs that allow the user to enter grades in a gradebook. The first program will use one‐dimensional arrays, and the second program will use two‐dimensional arrays. The two programs function the same

Write an application that prints out the final grade of the students in a class and the average for the whole class. There are a total of 3 quizzes. You will need 4 arrays:

1. An array of type int to store all the ID's

2. An array of type double to store all scores for quiz 1

3. An array of type double to store all scores for quiz 2

4. An array of type double to store all scores for quiz 3

How to proceed:

1. Ask the user how many students are in the class, so you can set the length of all the arrays.

2. Allocate 4 arrays that will store the data.

3. Use a FOR loop to retrieve and store all the data.

4. Use another FOR loop to  

a. Output the final score for each student.

b. Keep track of all scores to later compute the average for the class.

5. Calculate and Output the average for the class.

Format all floating‐point numbers to 2 decimal places

Your program MUST receive user input as shown in the sample output.

Please leave comments on the program so i can give you a thumbs up :)!

The algorithm is basically as follows. The notation is slightly different from that in the website you were given, but there is no difference in the method.

Given the initial value problem

dy/dx=f(x,y),y(a)= y_0

Euler’s Method with step size h consists in applying the iterative formula

y_(n+1)= y_n+h∙f(x_n,y_n ),n≥0

To compute successive approximations y_1,y_2,y_3,⋯ to the (true) values 〖y(x〗_1),〖y(x〗_2),〖y(x〗_3),⋯ of the exact solution y=y(x) at the points x_1,x_2,x_3,⋯, respectively.

In plain English:
You want to approximate the value of dy/dx (or y’) at some point in an interval.

Step 1: Depending on how accurate you need to be, divide the interval up into little pieces of equal length; this length is the step size h. For purposes of discussion, let’s use the interval [0,1] and use ten intervals, so h = 0.1.

Step 2: y_0=0
Step 3: y_1=y_0+0.1f(x_0,y_0)
Step 4: y_2=y_1+0.1f(x_1,y_1)
…
Stop after ten steps, in this case. Usually the stopping criterion is a level of accuracy.

You can easily set this up in Excel.
