Let T(x) = Ax for the given matrix A, and find T(u1) and T(u2) for the given u1 and u2. A = 4 2 −5 6 , u1 = −4 −3 , u2 = 2 −5 T(u1) = -22 2 .

T(u1) = , T(u2) =

Step-by-step explanation: Matrix A = , u1 = , u2 =

If T(x) = Ax and it wants to find T(u1), it means

T(u1) = ·   = =

To find T(u2):

T(u2) =   · = =

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

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
