I need help with the first questions!! Question: Which SINGLE transformation can map figure PQRS onto figure P’ Q’ R’ S’ ?

Units:

P(2,2) Q(5’2) R(5,6) S(2,6)

P’(-6’2) Q’(-3,2) R’(-3,6) S’(-6,6)

A) Translation of 8 units down

B) Translation of 8 units up

C) Translation of 8 units to the left

D) Translation of 8 units to the right

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
