Answer:

(d) -√((2+√2)/(2-√2))

Step-by-step explanation:

5π/8 is a 2nd-quadrant angle whose reference angle is greater than π/4. This means the tangent is negative with a magnitude greater than 1. The only reasonable choice is ...

$\displaystyle -\sqrt{\frac{2+\sqrt{2}}{2-\sqrt{2}}}$

6.5 x 1/9 please help

hjlf

Answer:

13/18

Step-by-step explanation:

6.5 · 1/9 = 6 5/10 · 1/9
6 5/10 · 1/9 = 6 1/2 · 1/9
6 1/2 · 1/9 = 13/2 · 1/9
13/2 · 1/9 = 13/18

Therefore, 6.5 · 1/9 = 13/18.
