Exponential growth: the world population was 2010 about 7 billions; the yearly population growth is just below 2%. assuming r=2% being stable:
how much time did elapse since the people were only 3.5 billion?
[type the nummerical value rounded to full years ]

time is 24.66 years

Step-by-step explanation:

Given data

population A = 7 billion

rate = 2% = 0.02

population P = 3.5 billion

to find out

time

solution

we will apply here formula that is

A = P

here put all value

7 = 3.5

take ln both side

ln (7/3.5) = ln

0.02t = ln2

t = ln2 / 0.02

t = 24.66

so time is 24.66 years

the answer is. -82562234434584

step-by-step explanation:

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
