Answer:

Third option.

Step-by-step explanation:

This is matrix addition, so we have to add the corresponding parts of the matrix correctly. The first would be 12+(-3), getting 9. The second part would be (-5)+(-9), getting up -14. Third would be 0+(-14), getting -14. Last would be (-7)+10, getting 3. So, the option with all of the correct parts in their respective positions would have to be the third option.

Hope this helped!

Answer:

1 -√2

Step-by-step explanation:

$\tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}$
