Answer:

1 -√2

Step-by-step explanation:

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

tan(7π/8) = 1 -√2

A drink is mixed in the ratio

Contact [7]

Answer:

Step-by-step explanation:

Drink mix ratio:

Lemonade : Orange : Cranberry

6 : 3 : C

Fraction of Cranberry juice = $\frac{3}{12}$

Sum of the ratio = 6 + 3 + C = 9 + C

Fraction of Cranberry;

$\frac{C}{9 + C}$ = $\frac{3}{12}$

3(9 + C) = 12C

27 + 3C = 12C

27 = 12C - 3C

9C = 27

C = 3

The missing number will be 3

Please help me out with this problem!!!!!!

Answer:

Step-by-step explanation:

The line with positive slope is 3x-5y≥15 and the line with negative slope is 2x+3y≤12.

This is because such inequalities represent half planes which are divided by the corresponding lines.

Put (0,0) in both lines to check if the origin lies in the shaded half plane or not.
