If y is inversely proportional to x, and y is 9 when x is 4, find the constant of variation k, and determine the value of y when x is 8. (If necessary, round your values to the nearest tenth.)

The constant of variation K is ___ and y is ___ when x is 8.

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
