Answer:

Element wise subtraction.

Step-by-step explanation:

Matrix Subtraction is done element wise.

Therefore, D = \[  \left[ {\begin{array}{ccc}   3 & 1 & 0 \\   -1 & 2 & 4 \\9 & 7 & -2  \end{array} } \right]\] - \[  \left[ {\begin{array}{ccc}   5 & 2 & -4\\   1 & 12 & 3 \\ 11 & 3 & -2  \end{array} } \right]\]

This becomes:

\[   D =  \left[ {\begin{array}{ccc}   -2 & -1 & 4 \\    -2 & -10 & 1 \\    -2 & 4 & 0  \end{array} } \right]\]

Now, $ d_{11} = -2 $

$ d_{12} = -1 $

$ d_{13} = 4 $

$ d_{21} = -2 $

$ d_{22} =  -10 $

$ d_{31} = -2 $

oee [108]

Answer:

12.56 square cm

Step-by-step explanation:

Central \:angle \:(\theta) = 40°\\Radius \: (r) = 6 cm

Let A be the area of the sector of circle.

\therefore \: A =  \frac{\theta }{360 \degree}  \times \pi {r}^{2}  \\  \\=  \frac{ 40 \degree}{360 \degree}  \times 3.14\times {6}^{2}  \\  \\    =   \frac{ 1}{9}  \times 3.14 \times  36 \\  \\  =   3.14 \times 4 \\ \\ = 12.56 \:  {cm}^{2}
