5.one stick of butter is equivalent to 1/2 cup of butter. a recipe calls for 2 tablespoons of butter. there are 16 tablespoons in a cup. how much of a stick of butter should you use?
show work for all !

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

definitely a. the others have almost all data points on one side of the line.
