Can you think of any 2x2 matrices d for which cd = dc for all 2x2 matrices c? give 2 different examples of such matricesd.
Ksju [112]
For any arbitrary 2x2 matrices \mathbf C and \mathbf D, only one choice of \mathbf D exists to satisfy \mathbf{CD}=\mathbf{DC}, which is the identity matrix.

There is no other matrix that would work unless we place some more restrictions on \mathbf C. One such restriction would be to ensure that \mathbf C is not singular, or its determinant is non-zero. Then this matrix has an inverse, and taking \mathbf D=\mathbf C^{-1} we'd get equality.

A rational expression is undefined whenever its numerator is zero.
kipiarov [429]

Answer:

False

Step-by-step explanation:

for a rational number expressed as (A / B) where A & B are integers

if the numerator (A) is zero, then (A/B) is simplify zero

i.e (A / B) = (0 / B) = 0

however if the denominator (B) is zero, then by definition any value divided by zero is undefined.

(A / B) = (A / 0) = {undefined}
