Exercise 2.1.47 Prove that ifA^-1 exists and AX=0 then X =0.

Mathematics
1 answer:
stepan [7]3 years ago
5 0

Answer:

Step-by-step explanation:

If A^{-1} exist, then we have that A^{-1}\cdot A=1.

Therefore, in the case that AX=0, if we multiply both

terms in the equation by A^{-1}, then we have

A \cdot A^{-1}X=A^{-1}0

and so the equation tells us that

X=A\cdot A^{-1}X=A^{-1}0=0.

Rogers Company reported net income of $35,000 for the year. During the year, accounts receivable increased by $7,000, accounts p
storchak [24]

Answer:

correct answer is  option C.

Step-by-step explanation:

net income of a year =  $35,000

accounts receivable is increased (AR)= $7,000

accounts payable decrease(AP) = $3,000

depreciation expense = $8,000

net cash provided = net income - increase in current asset (AR) - decrease in  current asset (AP) +non cash flow

net cash provided =  $35,000 -$7,000-$3,000+ $8,000

                               = $33000

hence the correct answer is  option C.
