A fish is 5 feet below the surface of a lake. If its position can be recorded as -5 feet, what would the position of 0 represent?
O the distance above the surface of the lake
O the distance below the surface of the lake
O the surface of the lake
the height of the fish

i believe the answer to be 48

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
