Solve each item supporting your answer with clear explanation.

1.Consider the following augmented matrix of a system of linear equations.

( 7 −3 4 6

−3 2 6 2

2 5 3 −5 )

a. Solve the system with the Jacobi method. First rearrange to make it diagonally dominant if possible. Use [0,0,0] as the starting vector. Find the condition number of the matrix of coefficients κ_∞(A), and compute how many iterations are required to get the solution accurate to five significant digits?

b. Repeat part a) using the Gauss-Seidel method. Are fewer iterations required?

c. Is convergence faster in parts a) and b) if the starting vector is [-0.26602, -0.26602,-0.26602]?

Set up the augmented matrix that describes the situation, and solve for the desired solution. A bag of mixed nuts contains cashews, pistachios, and almonds. Originally there were 850 nuts in the bag. 30% of the almonds, 20% of the cashews, and 10% of the pistachios were eaten, and now there are 715 nuts left in the bag. Originally, there were 50 more cashews than almonds. Figure out how many of each type of nut was in the bag, to...

1---- . Is the statement "Elementary row operations on an augmented matrix never change the solution set of the associated linear system" true or false? Explain. A. True, because elementary row operations are always applied to an augmented matrix after the solution has been found. B. False, because the elementary row operations make a system inconsistent. C. True, because the elementary row operations replace a system with an equivalent system. D. False, because the elementary row operations augment the number...
