Explain how you can solve the following problems using the QR factorization. (a) Find the vector x that minimizes ||Ax − b1||^2 + ||Ax − b2||^2 . The problem data are the m × n matrix A and two m-vectors b1 and b2. The matrix A has linearly independent columns. If you know several methods, give the most efficient one. (b) Find x1 and x2 that minimize ||Ax1 − b1||^2 + ||Ax2 − b2||^2 . The problem data are the...

You are allowed to use any sources you like. Make sure to cite any sources you use (any reasonable citation style is fine). Do not copy text from any source (short, cited quotes OK). Question: In a species of deer, you find an allele that causes females to always produce an equal number of male and female offspring. Present an argument affirming that this sex ratio is an evolutionary stable strategy. Then, try to present a plausible scenario in this...

When you use a numerical method like the finite element method, you divide a large body into an equivalent system of smaller bodies called elements. This is done because using an analytical method on the larger body may require a solution to a boundary value partial differential equation; a task that might be difficult or impossible to solve. The question: why does dividing a large object into smaller objects help at all? If you divide a rectangle into tiny rectangles...

You determine the format. I would like you to use some computer application, not pen and paper. I would suggest WORD for any analysis comments and EXCEL for any spreadsheet analysis (Horizontal/Vertical) You are analyzing a company from a financial standpoint and comparing them to another company. Make it easy for us to read and understand. Make a recommendation to deal with this company or not based on your analysis. Choose a company from the following public companies. That means...
