Answer :
Answer:
5126.52
Step-by-step explanation:
Time = 25 years
Population after 25 years = 29000
Biologists observe that the population doubles every 10 years, and now the population is 29,000
No. of 10 years in 25 years = [tex]\frac{25}{10}=2.5 years[/tex]
So, t = 2.5 years
Rate = 2
Formula = [tex]y=ab^t[/tex]
y is the population after t years
a is the initial population
b = rate
t = time
[tex]29000=a(2)^{2.5}[/tex]
[tex]\frac{29000}{(2)^{2.5}}=a[/tex]
[tex]5126.52=a[/tex]
Hence the initial size of the bird population is 5126.52
