<em>Answer</em></h2>
<em>361</em><em>π</em><em>km²</em>
<h2>
<em>Explanation</em></h2>
• the formula to find the area of a circle is A=πr²
<h3> =>
<em>A=π(19km)²</em></h3><h3>
<em>A=π(19km)² => A=361πkm</em>²</h3><h2>

The fraction is 2/6, because he has six ties which gives you the denominator of six and 2 are red. to simplify 1/3
we know that
in the right triangle ABC
the value of cosine of angle x is equal to
![cos(x)=\frac{AC}{AB}](https://tex.z-dn.net/?f=cos%28x%29%3D%5Cfrac%7BAC%7D%7BAB%7D)
we have
![AC=3.4\ cm\\AB=10\ cm](https://tex.z-dn.net/?f=AC%3D3.4%5C%20cm%5C%5CAB%3D10%5C%20cm)
substitute the values
![cos(x)=\frac{3.4}{10}=0.34](https://tex.z-dn.net/?f=cos%28x%29%3D%5Cfrac%7B3.4%7D%7B10%7D%3D0.34)
Find the measure of angle x
![x=cos(x)^{-1} =arc\ cos(0.34)=70.12\°](https://tex.z-dn.net/?f=x%3Dcos%28x%29%5E%7B-1%7D%20%3Darc%5C%20cos%280.34%29%3D70.12%5C%C2%B0)
Round to the nearest whole degree
![x=70\°](https://tex.z-dn.net/?f=x%3D70%5C%C2%B0)
therefore
<u>the answer is</u>
![70\°](https://tex.z-dn.net/?f=70%5C%C2%B0)
Answer:
sqrt(x)
Step-by-step explanation:
1/ ( x^(-3/6))
We can simplify the fraction
1/ ( x^(-1/2))
A negative exponent means that since it is in the denominator, it goes to the numerator. It still keeps the exponent.
x^ (1/2)
sqrt(x)
Answer:
17
Step-by-step explanation:
f(x) = x + 8
f(9) = 9 + 8
= 17
