Help with the hw would be greatMichael Chiu Math3C-A1-M12-Jaramillo WeBWorK assignment number HW 8 is due : 07/28/2012 at 11:59pm PDT. The (* replace with url for the course home page *) for the course contains the syllabus, grading policy and other information. This ?le is /conf/snippets/setHeader.pg you can use it as a model for creating ?les which introduce each problem set. The primary purpose of WeBWorK is to let you know that you are getting the correct answer or to alert you if you are making some kind of mistake. Usually you can attempt a problem as many times as you want before the due date. However, if you are having trouble ?guring out your error, you should consult the book, or ask a fellow student, one of the TA’s or your professor for help. Don’t spend a lot of time guessing – it’s not very ef?cient or effective. Give 4 or 5 signi?cant digits for (?oating point) numerical answers. For most problems when entering numerical answers, you can if you wish enter elementary expressions such as 2 ? 3 instead of 8, sin ( 3 * pi / 2 ) instead of -1, e ? ( ln ( 2 )) instead of 2, ( 2 + tan ( 3 )) * ( 4 - sin ( 5 )) ? 6 - 7 / 8 instead of 27620.3413, etc. Here’s the list of the functions which WeBWorK understands. You can use the Feedback button on each problem page to send e-mail to the professors. 1. (1 pt) Write the system of equations in matrix-vector form, then write the augmented matrix of the system. 3 i + 3 j + 4 k + 3 l = 5 2 i - 4 j + 3 k = 2 ± ² ? ? ? ? ? ? ? ? = ± ² ± ² 2. (1 pt) Write the system of equations in matrix-vector form, then write the augmented matrix of the system. 5 w + 5 x - 2 y = 0 ³ ´ ? ? ? ? = ³ ´ ³ ´ 3. (1 pt) Consider the matrix ± 1 0 2 0 0 1 ² Which condition or conditions of being in RREF does the matrix fail? • A. Zero rows are at the bottom • B. The leftmost nonzero entry of each nonzero row equals 1 • C. Each pivot is further to the right than the pivot in the row above it • D. Each pivot is the only nonzero entry in its column • E. None of the above, it is in RREF 4. (1 pt) Consider the matrix ? ? 0 5 8 0 2 2 0 6 6 ? ? Which condition or conditions of being in RREF does the matrix fail? • A. Zero rows are at the bottom • B. The leftmost nonzero entry of each nonzero row equals 1 • C. Each pivot is further to the right than the pivot in the row above it • D. Each pivot is the only nonzero entry in its column • E. None of the above, it is in RREF 5. (1 pt) Consider the matrix ? ? 1 10 7 0 0 0 0 0 0 ? ? Which condition or conditions of being in RREF does the matrix fail? • A. Zero rows are at the bottom • B. The leftmost nonzero entry of each nonzero row equals 1 • C. Each pivot is further to the right than the pivot in the row above it • D. Each pivot is the only nonzero entry in its column • E. None of the above, it is in RREF 1
