4 We consider the following initial value problem for two functions y(x),z(x): 0=y′′+(y′+6y)cos(z), 5z′=x^2+y^2+z^2, where 0≤x≤2 and y(0)=1.7, y′(0)=−2.7, z(0)=0.5. Approximate the solution of this initial value problem using Euler's method with 100 steps. (use Maple) What approximation value do you obtain for y(2) and z(1)?

4.1.1 Complete solution and answer only no need explanation Given three data points (1,6), (3,28), and (10, 231), What is the value of y at x = 2 if the function y = 2x2 + 3x + 1 passes through the three data points.

3. The diagram below shows the main land routes for vehicular traffic between points A and G in a city. The figures in the arcs represent the cost of traveling between each pair of nodes. a) Manually apply Dijkstra's algorithm to find the cheapest route between A and G (visited nodes and total distance). b) Formulate a linear programming problem in extended form, to determine the shortest route to travel from A to G. Do not use subscripts, name 14 variables, for example XFE would be the variable that indicates that the arc from F to E is used. c) If there is a fixed cost for visiting each node, modify the formulation of the problem to include said fixed cost in the objective function, and the variables and restrictions that are required.
