a countrys population in 1994 was 72 million. in 1998 it was 81 million. estimate the population in 2016 using exponential growth formula. round your answer to the nearest million.?
+23254 Assuming a constant growth rate:
Final Number = Beginning Number x ( rate ^ time ) (time: 1998 - 1994 = 4)
81 000 000 = 72 000 000 · r ^ 4
Dividing both sides by 72,000,000: 1.125 = r^4
Finding the fourth root of both sides: r = 1.030
Using the formula to estimate the population iin 2016 (2016 - 1994 = 22):
Final Number = 72 0000 000 · 1.030 ^ 22 = 138, 000, 000 (rounded)
