8. the value of x varies directly with y, and

when x = 14, y = 21. write an equation to

represent the direct variation.

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

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
