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
Write a python program that return the total aquaculture production by Year, Region, and Type/Environment. You must disregard the Philippines in the region column.

Create a line chart of the result that can be filtered by Type/Environment. Set the hvplot x parameter to Year and by parameter to Region, and groupby parameter to Type/Environment.

Computer Science C++ please, use Monte Carlo integration to calculate the volume of a d-dimensional hypersphere of radius r = 1. (Note that for d=1, 2, and 3, the common names for d-dimensional volume are length, area, and volume, respectively.) Print out each volume and narrow the answer down to 4 digits with 99% confidence. How far can you push d for this method?
Write a MATLAB function sumOddInts(). sumOddInts should return the sum of all odd integers between the values provided to the two parameters, inclusive, e.g., sumOddInts(5,9) should return 21. start and finish do not have to be odd, e.g, sumOddInts(4,8) should return 12. start and finish do not have to be positive, e.g., sumOddInts(-5,7) should return 7, However, finish may be assumed to be greater or equal to start. whereas Python has a modulo operator "%", MATLAB has a built-in mod() function that returns the remainder. For instance, >> mod (13,5) ans = 3>> mod (13,2) ans = 1
Write your own Python program where a non-intrinsic function solves for all the roots of a cubic polynomial given by the mathematical function g(x)=ax³+bx²+cx+d where a,b,c and d are nonzero real numbers given by the user. Afterwards, the program will also solve for the sum and product of these roots. You must be able to create a function for getting the sum, and another for the product and use it in your main program. (HINT: Use Cardano's formula).
