Using python solve the given problems: Problem: USA has the largest army that exists in the world. In USA it is always the military officer's main worry to order his soldiers on parade correctly. Luckily, ordering soldiers is not really such a problem. If a platoon consists of n men, all of them have different rank (from 1 - lowest to n - highest) and on parade they should be lined up from left to right in increasing order of rank. Sounds simple, doesn't it? Well, Sgt Johnny thought the same, until one day he was faced with a new command. He soon discovered that his elite commandos preferred to do the fighting, and leave the thinking to their superiors. So, when at the first rollcall the soldiers lined up in fairly random order it was not because of their lack of discipline, but simply because they couldn't work out how to form a line in correct order of ranks. Sgt Johnny was not at all amused, particularly as he soon found that none of the soldiers even remembered his own rank. Over…

Use PYTHON to determine the intersection points for the sets of equations shown below. Use the solve function when possible. Otherwise, use other appropriate built-in function taught earlier. Graph the equations with different colors and plot the intersection points with green square markers. Include proper legends a) -10x + y = 6 2x³ - 3y = 15 b) 8x - y = -12 4x + 5y = 27
In Python 3! (1) Prompt the user for a title for data. Output the title. (1 pt)Ex: Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored (2) Prompt the user for the headers of two columns of a table. Output the column headers. (1 pt)Ex: Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels (3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers. (4 pts)Ex: Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6 (4) Perform error checking for the data point…
