Approximately how many flops are needed to find the LU factorization of an n x n matrix using Doolittle’s method? If a computer requires 1 second to find an LU factorization of a 500 x 500 matrix, what would you estimate is the largest matrix that could be factored in less than 1 hour?

How does the linear factorization of f(x), that is, f(x)=an (x−c1)(x−c2)⋯(x−cn), show that a polynomial equation of degree n has nroots? Why must every polynomial equation with real coefficients of degree 3 have at least one real root? If you are given the equation of a rational function, explain how to find the vertical asymptotes, if there is one, of the function's graph. If you are given the equation of a rational function, explain how to find the horizontal asymptote,...

Given the function N(x)=x^(1.2) + x -ln(x) - 2 Find the roots of N(x) in the domain 0.1 ? x ? 2.5 using the MATLAB fzero function. Plot N(x) using fplot to find the estimates of the roots. Use a for-loop that calls the fzero function and prints the roots to 3 decimal places. Define N(x) using an anonymous function definition, and pass your function using your anonymous function

How many studs are needed to construct 100 feet of a 2 x 4 stud wall?...

How many studs are needed to construct 100 feet of a 2 x 4 stud wall? The wall has one 8-footwide window, four 4-foot-wide windows, two 36-inch-wide doors, one 30-inch-wide door, four corners, two intersections, and eight hold downs located at corners. The stud spacing is 16 inches on center. Allow for two additional studs for each corner, intersection, or doorway; six additional studs for each window less than 6 feet in length; eight additional studs for each window 6...
