Answer:
(1,3)(5,-5)(3,-1)
Step-by-step explanation:
This means the radius is 10 units. For it to be a circle, any point that lies on the circle is the same distance from the moving point to a fixed point (the centre). This distance is the radius.
As such, any other point that lies on the circle is 10 units from the centre as well.
We assume the annual percentage increase is the same. We will work out the constant k using the formula
We have
P = 76
A = 72
t = 6 years (from 1992 to 1998)
Substitute into the formula


Take log both sides give



We can now work out the number of population by the end of 2012 using the formula
We have
A = 72 million
k = 0.009
t = 10 years (1992 to 2012)


≈79 million
