Since we are going to repeatedly solve the system a⃗x = ⃗b in the next problem, it makes sense to use lu decomposition. use the lu command to compute the lu factorization with partial pivoting lu = pa of the matrix a that you found in problem 1 as follows, [l, u,p] = lu(a); save the matrices l, u, and p into the files a4.dat, a5.dat, and a6.dat, respectively. solve the system a⃗x = ⃗b for the same values of w8, w9, w10, w11 you used in problem 2 using lu factorization with partial pivoting. save the intermediate result ⃗y (obtained through forward substitution, preceding backward substitution for ⃗x) to the file a7.dat and the final answer to the file a8.dat.

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
