Computer Science c++ || urgent Write the code for choosing the list of items in order to get the maximum profit of fractional knapsack problem. [NOTE: number of input items should be user interest, and output should be like - firstly print the resulting profit table, and then print the all selected items (must not be all items from the inputted items - means that all inputted items should not be as the selected items) for the knapsack and then print the maximum profit.]
The liquid-liquid extraction process carried out at the Electrochemical Materials Laboratory involves the extraction of nickel (Ni) from the liquid phase into an organic phase. Data from laboratory experiments are given in the table below. Ni phase cair, a (gr/l) 2 2,5 3 Ni phase organik, g (gr/l) 8,57 10 12 Assume that a is the amount of Ni in the liquid phase, and g is the amount of Ni in the organic phase. Quadratic interpolation is used to estimate the value of g, which is given by the following formula: g = x1a? + x2a + x3 a. Find three simultaneous equations based on the data given by the experimental results. b. Use the Gauss Elimination method to get the values of x1, x2 and x3 and then estimate the amount of Ni in the organic phase, if 2.3 g/l of Ni is available in the liquid phase. c. Use the LU Decomposition method to get the values of x1, x2 and x3. and then estimate the amount of Ni in the organic phase, if 2.3 g/l of Ni is available in the liquid phase.
1. Visualize the function graph with Python and find points where the curve intersects the X axis. 2. Find roots of an equation using a Python implementation the fixed-point iterations method. Note: Functions in tasks 1 and 2 are the same. So, the function graph built in task 1 can help with defining an initial point for the fixed-point iteration method. 3. Resolve the system of linear algebraic equations using the Python Numpy library. 4. Approximate the definite integral using the Scipy Python library. X = x = V3x –1 УЗх — -

HW3_3 Using built-in functions a) Use the built-in function roots to find all the roots of the polynomial g(x) = x¹+65x³ + 86x + 128. Print your results. b) Given f(x) = x³ – 5x + 10 and g(x) = 4 sin(3x) + 6 Graph these two functions (using different colors for the lines) such that all intersection points are shown. Solve for the intersection points and plot them on the graph with red stars. Use the built-in function brentq. Note: Import appropriate libraries.
