Find the DIFFERENCE between Matrices H and E. That is: [H] - [E]. Name it, "Matrix I". 5. AUGMENT Matrix C with Matrix I. Write them in both in MATRIX AND EQUATION FORM. Remember: Ax=B, or in this case, Ix=C. Use the variables: w, x, y and z when writing them in equation form. 6. Using the formula discussed in class, determine if Matrix is DIAGONALLY DOMINANT. If yes, proceed to section 2. If not, rearrange Matrix I so that it becomes diagonally dominant. Since we have previously augmented matrix I with C, rewrite the system of linear equations (just as with Item 5) with the CORRESPONDING rows from matrix C both in MATRIX AND…arrow_forwardThe number of non-zero entries in the adjacency matrix of the given graph is _____ a. 16 b. 10 c. 6 d. 4arrow_forwardReduce the following matrix to its r.r.e.f. 0 -3 -6 4. 6. 3. -1 1 -2 -1 -2 3. 3. 5-9-7 -1 1 4.arrow_forward

- Question 3 The owner decides he wants to employ only new trainee staff. He also wants only new trainee staff who are siblings of his permanent staff. He believes that each month, 5% of his permanent staff would have a sibling who would be suitable to start as a trainee staff member. His staffing model would therefore be defined by the rule S, = 75, + FS,, and the matrix S, giving the number of staff at the end of the first month in January 2013 would therefore be defined as S-75, + FS, where 0 0 0 0 0 0 0.05 0 0 0 0 o 0 0 0 o 0 0 0 10 0.8 0 0 0 T = O 09 0.7 0 20 and F= 60 0.2 0.1 03 1 where the matrices T and 5, are the same matrices as used in Question 2.

The initial population vector is x0 = How many elk aged 1-2 years are there expected to be after 10 years? How many elk aged 0-1 years are there expected to be after 20 years? How many elk are there expected to be after 30 years? Calculate the dominant eigenvalue of the Leslie matrix good to 3 decimal places. λ1 = What is the long-term growth rate of this population of elk as a percent? growth rate = over/under 100%.) Are the elk thriving, static, or going extinct? ?
