Answer:
False
Explanation:
The correct answer is:
Maps that show population density are Thematic maps.
Thematic map is basically used to represent particular themes for particular geographical area. For example, population variation, temperature variation or population density, average annual income, rainfall distribution etc. Thematic map is also called special purpose and this can be quantitative or qualitative.
Physical maps is option is not true because physical maps are used to depict topography or natural landscapes or geographical features of an area such as mountains, deserts, bodies of water etc.
<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.

Answer: Kerogen
Explanation: a Kerogen is an organic substances that helps to permeate (has pores which allow the inflow and outflow of certain substances like air or watee)oil shells, Kerogen has not net been converted to oil.Kerogens are waxy in nature with complex structures,Kerogens can not be extracted using organic Kerogens also contain Sulfur and Nitrogen. Kerogen contains Hydrocarbons in the form of paraffin which disolves under high temperatures and pressure into substances similar to petroleum.
