Tanya deposits $2,800 at a rate of 3.5% interest compounded quarterly. What is Tanya’s balance after three months?

What is Tanya’s balance after six months?

What is Tanya’s balance after nine months?

What is Tanya’s balance after one year?

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
