Lesson 1.10: Jessie works at least 36 hours a week.
tutor and as a teacher. The number of hours Jessie works as a teacher (y) is at
least twice the number of hours she works as a tutor (x).
Write the set of inequalities that represents the constraints of the
situation and state a point (x, y) that is part of the feasible region.

She's right. She worked a total of 40 hours

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

486in is correct
