Lamar has received $2,000 each year for college from his grandmother for the four years that he was in high school. He has deposited the money on the same day each year in an account that pays 8% interest, compounded annually. Complete the table below to determine how much money Lamar has saved.

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

y > 1/3x

y < = -x + 4

hope this : )
