An оlder аdult pаtient whо hаs been diagnоsed with age-related macular degeneration (AMD) asks the nurse what actions could help slow or avoid the potential vision loss. Which recommendations would the nurse plan to make? (Select all that apply.)
Shоw аs much wоrk аs yоu cаn and provide the appropriate justifications. You may use technology to complete row reductions and find inverses as needed--no restrictions! Just write down your initial set up and the technology answer. The problems that indicate an explanation is needed, you could just provide supporting work as your justification. 1. 5pts 2. 10pts 3. 5pts. Address the prompt below and provide any supporting explanation. 4. 8pts A mathematician has found 5 solutions to a homogeneous system of 26 equations in 30 variables. The 5 solutions are linearly independent and all other solutions can be constructed by adding together appropriate multiples of these 5 solutions. Will the system necessarily have a solution for every possible choice of constants on the right side of the equation? Explain. 5. 7pts Suppose a nonhomogeneous system of 11 linear equations in 14 unknowns has a solution for all possible constants on the right side of the equation. Is it possible to find 4 nonzero solutions of the associated homogeneous system that are linearly independent? Explain. 6. 10pts Find the values of h for which the vectors are linearly dependent: . 7. 8pts Compute the determinant of the matrix by cofactor expansion. At each step, choose a row or column that involves the least amount of computations. 8. 12pts 9. 10pts Find the eigenpairs for the given matrix. 10. 15pts Find the eigenpairs for A. Then diagonalize the given matrix. A= 11. 10pts Consider the following vectors: a. Determine if u and v are orthogonal. Show supporting work. b. Find the distance between u and v. c. Find a unit vector in the direction of u.
