The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.
Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):
The only matrix that has a value of -24 in the position (1,1) is matrix B.
Therefore, the answer is matrix B.
Answer:D) 1 hr
Step-by-step explanation:
Given
Pump A and B can fill tank in
Pump A and C can fill tank in
Pump B and C can fill tank in
Let A be the total hr taken A therefore rate of
Let B be the total hr taken B therefore rate of
Let C be the total hr taken C therefore rate of
-----1
-----2
-----3
Adding 1,2 & 3
thus time taken by A,B and C combined is 1 hr
