Question

Scalar and matrix multiplication Find the product:

Answer 1

Answer:

a = 1 , b = 0 and c = 5

Step-by-step explanation:

The given matrix are,

[2  1   0]   X 1    -1    2     =   [a    b   c]

                  -1    -2   1

                   0     1    1

a = (2*1) + (1*-1) +(0*0) = 2 -1 + 0 = 1

b = (2*-1) + (1*-2) +(0*1) =-2 -2 + 0 = 0

c = (2*2) + (1*1) +(0*1) = 4 +1 + 0 = 5

Therefore the values of a,b, and c are

a= 1 , b = 0 and c = 5
