matrix Dr. Buchmann asks the class to calculate the inverse of the following One of your classmates gets A-¹, A = 1 0 2 1 -1 2 3 1 0 -1/3 1/3 1/3 1 -1 0 2/3 1/6 1/6

Diagonalize A = 12 0 21 0 00 -3 — and compute A2019

Which of the following matrix multiplications would be possible to do? Select one: a. a 5x6 matrix with a 6 x 3 matrix b. a 2 x 2 matrix with a 3 x3 matrix С. a 5x3 matrix with a 3 x 3 matrix d. a 4x3 matrix with a 3 x 3 matrix

III. Used series of Elementary Row/Column Operations transform matrix given below into Row-Echelon Form (REF) or Reduced Row-Echelon Form (RREF). Fill in the blank box with the elementary operations for the given step and the corresponding result matrix. Use the word "over" without a space between the numerator and denominator to indicate the fraction bar or vinculum. Also, for the interchange symbol, write the word "interchange" with no spaces between the rows to be exchanged. For example, R2 is written as R2-2R1 R1 is written as (4over3)R1; -R2 is written as (-(1 over2)) R2; and R2-2R1 or -2R1+R2; and R2 R1 is written as R2interchangeR1. 3 [2 8 4 17) 2 14 5 1 5 10 -1 1.
