Use LU decomposition to solve the following system of equations
(show your work). Do not use a pivoting strategy, and check your
results by using the matrix inverse to show that [A][A]-1= [I].
4. (Applying LU and LUP decompositions) In this problem, we'll
use the LU/LUP decomposition to solve a linear system of
equations.
a) For A = [12 -8 13 -1 13;14 11 -5 -5 -7;1 -8 -9 10 8;-11 10 -8
3 8;-11 -8 4 2 -4] find matrices P, L, and U so that PA = LU using
Matlab's lu function. Based on your results: did Matlab use
pivoting during the lu-computation?
b) For b = [4;-4;-5;3;7] solve Ax =...
Solve the following system of
equations using LU factorization without partial
pivoting:
2x1 - 6x2 - x3 =
-38
-3x1 - x2 + x3 =
-34
-8x1 + x2 - 2x3 =
-20
in parts a and b use gaussian elimination to solve the system of
linear equations. show all algebraic steps.
a. x1 + x2 + x3 = 2
x1 - x3 = -2
2x2 + x3 = -1
b. x1 + x2 + x3 = 3
3x1 + 4x2 + 2x3 = 4
4x1 + 5x2 + 3x3 = 7
2x1 + 3x2 + x3 = 1
Solve the following set of equations with LU factorization with
pivoting:
3x1 -2x2 + x3 = -10
2x1 + 6x2- 4x3 = 44
-8x1 -2x2 + 5x3 = -26
Please show all steps
Please solve the following breakeven analysis problem
and show all systems of equations and work. (Excel solver
is not neccessary for this problem)
Jim and Pam are going to Culinary School! There are a group of
students at the school who are drug dealers, and the Captain has
received information that they are looking to start selling a
dangerous new street drug to the residents of the town nearby. Jim
and Pam infiltrate this group and propose that they use...
SET UP BUT DO NOT SOLVE the following system of linear
equations:
A company sells three sizes of fruit trays. The small size
contains 200 gr of watermelons and 100 gr of grapes. The medium
size contains 400 gr of watermelons, 100 gr of pineapples, and 300
gr of grapes. The large size contains 600 gr of watermelons, 200 gr
of pineapples, and 400 gr of grapes. Suppose that the company
receives an order for 28 kg of watermelons, 6...

a) Consider a typical $1,000,000 Canadian mortgage
contract. Suppose that the current nominal interest rate is 6% and
the maturity is set at 20 years. The rollover period is 3 years.
The borrower and lender agree to an annual mortgage payment scheme.
Find (i) the annual payments on this mortgage for the first three
years and (ii) the amounts for the principal and interest
components of each of these...
Solve the following system. If the system's equations are
dependent or if there is no solution, state this.
