Answer:
convergence between a continental plate and an oceanic plate
Explanation:
The Andean Mountain Range has been formed because of volcanic activity. This has happened because of a convergent plate boundary between two plates.
More specifically, the convergent plate boundary is between the continental South American plate and the oceanic Nazca plate. The Nazca plate is lower, denser, heavier, and it is moving below the South American plate, creating a subduction zone.
Where the boundary is between the two plates, the mantle manages to push through magma upwards through the cracks in the crust. This magma managed to get to the surface, lift up the land and create volcanoes, creating a continental volcanic arc parallel to the plate boundary, over time becoming the enormous Andean Mountain Range.
<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.
