Because we do not have the same reading material as you do, we do not know the solution. In addition to that, you are posting the question in the wrong section. This is an economics question. Refer to your required text for the class for the solution.
The answer is D because to use Pythagorean Theorem it has to be a right triangle.
I think that 22=4. please don't be mad if in wrong.
The right answer is The Same Length.
The triangle displayed is Isosceles. The explanation of this statement is the fact that the Line which is making a right angle it is also the one that slices the segment into equal segments. Mathematically speaking, in our triangle the
Median is perpendicular on the segment from which results that the triangle is Isosceles and x = y.
This can be modeled as:
P(y)=6X10^9(1.014)^(y-2000)
P(2010)=6,894,944,907
P(2075)=17,021,501,805
P(2120)=31,820,415,782 (all to the nearest whole person :) )
