Answer:
stratosphere
Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer” (see Figure Q1-2).

<em>Answer:</em>
<em>Find the perimeter of the polygon with the vertices UC - 2, 4), V(3, 4), and W(3. – 4).</em>
<em>Explanation:</em>
<em>this is a right triangle, where one angle is 90 degrees. Two sides are perpendicular to each other.
</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>U to V have the same y values so the distance is the difference in x values or 3 - (-2) = 5
</em>
<em>
</em>
<em>V to W have the same x values, so the distance is the difference in y values or 4-(-4) = 8
</em>
<em>
</em>
<em>U to W is the hypotenuse of the right triangle, = sqr(sum of squares of the other 2 sides) = sqr(25+64)=sqr(89)
</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>Perimeter = sum of the 3 sides = 5 + 8 + sqr(89) = 13 + sqr89 = 13 + 9.44 = 22.44
</em>
<em>
</em>
<em>81 is 9 squared. 100 is 10 squared. 91 is about 9.5 squared. Rounded to 2 decimal places, it's 9.44
</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>It might help if you plot the 3 points on a graph. That makes it clear you're dealing with a right triangle.
</em>
<em>
</em>
<em>
</em>
<em>
</em>
<em>Or if you want, you could have used the distance formula on all 3 sides, but it simplifies to the above.
