1. Describe, with justification, the possible reduced row echelon forms of a matrix A in the following cases: (a) A is a 2 × 4 matrix whose columns span R?. (b) A is a 3 × 4 matrix whose columns span R³. (c) A is a 4 × 4 matrix whose columns span R4.
I thought that a matrix spanned Rn if there was a pivot in every row. However, when a matrix is linearly dependent and the last row is made up of zeroes, it could still end up potentially spanning Rn. I'm a little bit confused about how that works because there isn't a pivot in every row in that situation. How does it still span when there's a free variable? For context, I'm looking at Practice Problem 2 in Section 1.3 of the Vector Equations notes in the textbook Linear Algebra and Its Applications, Fifth Edition by David C. Lay, Steven R. Lay, and Judi J. McDonald. If a picture should be needed, here it is.
Step 6. As seen in Steps 4 and 5, it takes some very special conditions, indeed, for two matrices to commute. Make up one more size 3 x 3 example. Be sure your example is different from that given in Step 4. In other words, provide two matrices A and B such that AB= BA. But, this time, make sure your matrices A and B are not diagonal. In the table below, enter your matrices A and B and verify that their products AB and BA are the same. Simplify your results as much as possible. A B АВ B BA Step 7. For this final step, let M be the set of all matrices and let D be the subset consisting of all 3 x 3 diagonal matrices. Conclusion. From the results of this and previous exercises, we have found that the set D commutative under matrix multiplication because AB = BA for matrices A and B in D By contrast, note that M commutative because AB = BA for matrices A and B in M. So, while M is not there exist subsets of M which are. And, D is just one example: can you think of others?
2. For each part, write a matrix in reduced row echelon with the given properties. Your answers must have at least 2 rows and at least 2 columns. If such a matrix is not possible, state why. (a) Is always solvable and 2 dependent variables. (b) Has a unique solution and columns are spanning. (c) Columns are dependent and the transformation is one-to-one. (d) Has more rows than columns and the transformation is onto.
Use a graphing calculator to find A¹, if it exists. A= A. 7 8 7 B 8 8 9 -1 -1 -1 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A1 = (Type an integer or a decimal for each matrix element.) B. The matrix A¹ does not exist.
Q21. Frankie has a very busy lunch counter. On Tuesday, they sold 356 meals and brought in revenue of $2,467. The vegetarian curry rice costs $7.00 and the Chicken Marsala costs $12.00. If the augmented matrix is given by [1 a b [7 c d Your Answer: T what is the value of d? Answer
Please explain part a and b. ( I have attached an answer key).
Please answer the question in the attached file. The more steps the better as I'm not confident what I've done so far.
