Question 96762: In 1975 the popultation of the earth was approximately 4 billion and dobuling every 35 years. The formula for the population P in Year Y for this doubling rate is P(in billions) = 4x 2(y-1975)/35. What will the population be in 2025 if tis growth rate continues?

P(year) = 4x 2^[(y-1975)/35]: P in billions.
What will the population be in 2025 if tis growth rate continues?
---------
P(2025)= 4*2^[(2025-1975)/35]
= 4^2^(50/35)
= 4*2^(10/7)
= 4*2^(1.42857...)
=4*2.6918...
=10.7672... billion
