Whats is the answer -2/3 (-1 1/6)
grin007 [14]

Answer:

\frac79

Step-by-step explanation:

\frac{-2}{3} \cdot-1\frac{1}{6}

Let's convert the mixed number to an important fraction.

-1 1/6 = -7/6

Now multiply:

\frac{-2}{3} \cdot \frac{-7}{6} = \\\\\\\frac{-2\cdot-7}{3\cdot6} = \\\\\\\frac{14}{18} = \frac79

Answer:

\frac{\sqrt{17} }{7}

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sinx = \sqrt{1-cos^2x}

Note that (\frac{4\sqrt{2} }{7})² = \frac{32}{49}

sinΘ = \sqrt{1-(32/49)}

        = \sqrt{\frac{17}{49} } = \frac{\sqrt{17} }{7}
