One of the two nearly identical systems of equations below does not have a solution. Which one is it? Demonstrate how you determine your answer in a script and write your observations in comments. Print the solution for other system, using print statement.

I need help with programming in MATLAB. The following code transforms cartesian coordinates to the kepler elements. Can you give me the code for transforming kepler orbital elements to cartesian coordinates. The following code gives the 6 kepler elements. Transform those elements into cartesian coordinate that match the values under the Example Usage part of the code. Can you send a screenshot so I know the output of your code matches the input of the following code? I have asked this question twice and I have gotten the exact same code as the answer and it did not match. Please make sure the results match. % Example usage:x = 1000; y = 2000; z = 3000; vx = 4; vy = -3; vz = 2; [a, ecc, inc, raan, argp, f] = cart2orb(x, y, z, vx, vy, vz); % Display the resultsdisp(['Semi-Major Axis (a): ', num2str(a), ' km']);disp(['Eccentricity (ecc): ', num2str(ecc)]);disp(['Inclination (inc): ', num2str(inc), ' degrees']);disp(['Right Ascension of Ascending Node (raan): ',…
You need to take a trip by car to another town that you have never visited before. Therefore, you are studying a map to determine the shortest route to your destination. Depending on which route you choose, there are five other towns (call them A, B, C, D, E) that you might pass through on the way. The map shows the mileage along each road that directly connects two towns without any intervening towns. These numbers are summarized in the following table, where a dash indicates that there is no road directly connecting these two towns without going through any other towns. Miles between Adjacent Towns Town A B C DE Destination Origin A 40 60 50 10 70 B 20 55 40 50 10 D 60 E 80 (a) Formulate this problem as a shortest-path problem by drawing a network where nodes represent towns, links represent roads, and numbers indicate the length of each link in miles. (b) Use the Dijkstra's algorithm to solve this shortest path problem.

Write a computer program for calculating carburization heat treatments. The program should ask the user to provide an input for the carbon concentration at the surface (cs), and the concentration of carbon in the bulk (c0).
Scenario As you surely know, due to some astronomical reasons, years may be leap or common. The former are 366 days long, while the latter are 365 days long. Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the kind of year: if the year number isn't divisible by four, it's a common year, otherwise, if the year number isn't divisible by 100, it's a leap year. otherwise, if the year number isn't divisible by 400, it's a common year. otherwise, it's a leap year. none of the above year int(input("enter the year")) if (year%4 1-0) and (year%400 -0) or (year % 1000): print (year is common year") else: print(year, is leap year") year= int(input ("enter the year")) if (years !-0) or (year480 1-0) and (year % 1001-0): print(year is common year") else: print(year, "is leap year") D year= int(input("enter the year"))
Write a Java program that will create a twelve line times table from 8 to 19 based on user input. The table will have three columns centred correctly on the screen with proper column titles. All programs will have a title, introduction, correctly ask for user input and display the resultant design. Do not use any built-in math functions.
Modify the below code according to what is asking you to do. Show your modified code in a picture, please.

Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment
Your relative, who goes to primary school and has just learned the multiplication table, asks you to constantly ask him. You wanted to gamify it. The computer will randomly scan in the multiplication table and the user will write the answer on the screen. There will be 10 questions in total and at the end the number of questions, the number of correct answers and the number of wrong answers will be printed on the screen. Also, write a program that will print if the percentage of success is below 80, it remained, and if it was above, it passed. (On C# ConsoleApp(.Net Framework)
