\frac{7 \pi }{6} is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)
\frac{7 \pi }{6} - \pi = \frac{ \pi }{6}  (or 30 degrees)

sin \frac{ \pi }{6} = \frac{1}{2}

Juan purchased an antique that had a value of \$200$200dollar sign, 200 at the time of purchase. Each year, the value of the ant
garri49 [273]

Answer:

<h2>The value of a is (\frac{11}{10} )^{222}.</h2>

Step-by-step explanation:

At the time of purchase, the value of the antique is $200.

After one year the value will increase 10%.

Hence, after one year, the value of the antique will be \frac{110}{100} \times200 = 220.

Similarly, after two year, the value will be 200\times (\frac{110}{100} )^{2}.

Thus, 222 years after purchase, the value of the antique will be 200\times (\frac{110}{100} )^{222} = 200\times (\frac{11}{10} )^{222}.
