Question

@Nurali @nincompoop
he population of the world was 5.7 billion in 1995, and the observed relative growth rate was 2% per year. By what years will the population double and triple?

Answer 1

@Nurali u know how to do it

Answer 2

A = 5.7 • e^(0.02t)

2 • 5.7 = 5.7 • e^(0.02t)
2 = e^(0.02t)
ln 2 = 0.02t
34.65735903... = t
It wll double during the year 2029. (1995 + 34)

3 • 5.7 = 5.7 • e^(0.02t)
3 = e^(0.02t)
ln 3 = 0.02
54.93061443... = t
It will triple during the year 2049. (1995 + 54)

Answer 3

@Nurali what does the 5.7 come in

Answer 4

in question 5.7 billion

Answer 5

whats the equation again whats with the question marks?

Answer 6

@Nurali u get what im saying

Answer 7

@Nurali hello

Answer 8

Af=Aoe^(rt)
2=1e^(0.02t)
2=e^(0.02t)
ln(2)/0.02=t
t=34.65, so add 1995 and get 2029.65
ln(3)/.02= 54.93, add 1995 and get 2049.93
