Stock The table presents the 2016 percentage change in the stock price for sixwell-known companies. (Data from : finance.yahoo.com .) Company Percentage change American Express +10.6% Coca-Cola − 1.0 % ExxonMobil +14.9% Hewlett Packard +63.1% Ford − 5.7 % Red Robin Gourmet Burgers − 8.0 % Suppose that we wish to determine the difference in percentage change between two of the companies in the table, and suppose that we are interested only in the magnitude, or absolute value, of this difference. Then we subtract the two entries and find the absolute value. For example, the difference in percentage change of stock price for American Express and Ford is | 10.6 % − ( − 5.7 % ) | = 16.3 % Find the absolute value of the difference between the two indicated changes in stock price . Disposable Income The following graph shows the real per capita amount of disposable income (in thousands of dollars) in the United States. (Data from: Federal Reserve Bank of St. Louis.) For each of the following, determine the years for which the expression is true, wherex is the per capita disposable income. | x − 37 , 000 | > 1000

Find the absolute value of the difference between the two indicated changes in stock price.
Disposable Income The following graph shows the real per capita amount of disposable income (in thousands of dollars) in the United States. (Data from: Federal Reserve Bank of St. Louis.)
For each of the following, determine the years for which the expression is true, wherex is the per capita disposable income.
Function: y=xsinx
Interval: [ 0 ; π ]
Requirements:
Draw the graphical form of the function.
Show the coordinate axes (x and y).
Choose the scale yourself and show it in the flowchart.
Create a flowchart based on the algorithm.
Write the program code in Python.
Additional requirements:
Each stage must be clearly shown in the flowchart.
The program must plot the graph and save it in PNG format.
Write the code in a modular way (functions and main section should be separate).
Expected results:
The graph of y=xsinx will be plotted in the interval [ 0 ; π ].
The algorithm and flowchart will be understandable and complete.
When you test the code, a graph file in PNG format will be created.
A company specializing in lubrication products for vintage motors produce two
blended oils, Smaza and Nefkov. They make a profit of K5,000.00 per litre of
Smaza and K4,000.00 per litre of Nefkov. A litre of Smaza requires 0.4 litres of
heavy oil and 0.6 litres of light oil. A litre of Nefkov requires 0.8 litres of heavy oil
and 0.2 litres of light oil. The company has 100 litres of heavy oil and 80 litres of
light oil. How many litres of each product should they make to maximize profits
and what level of profit will they obtain? Show all your workings.
Use the graphs to find estimates for the solutions of the simultaneous equations.
