A chameleon is looking for prey. Let positive numbers represent the elevation of prey above the chameleon and negative numbers represent the elevation of prey below the chameleon. The chameleon spots a fly at 4 m and a grasshopper at −6m .
What does an elevation of 0m represent in this situation?
Choose 1

(A) The elevation of the fly

(B)
The elevation of the chameleon

(C)
The elevation of the grasshopper

(B)

The elevation of the chameleon

Step-by-step explanation:

the fly is above the chameleon, so it's elevation should be represented by a positive number

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
