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 =
So, t = 2.5 years
Rate = 2
Formula =
y is the population after t years
a is the initial population
b = rate
t = time
Hence the initial size of the bird population is 5126.52
Tan3A=tan(2A+A)
We know that , tan(x+y)=(tanx + tany)/(1 - (tanx)(tany))
tan(2A+A)=(tan2A+tanA)/(1 - (tan2A)(tanA))— (1)
We know that , tan2x=2tanx/(1 - tan^2x)
So, by substituting tan2A in (1),we get,
=[2tanA/(1 - tan^2A) + tanA]/1- (2tanA/(1 - tan^2A))(tanA)]
=[2tanA+tanA - tan^3A]/[1 - tan^2A - 2tan^2A]
=[3tanA - tan^3A]/[1-3tan^2A]
Therefore, tan3A= [3tanA - tan^3A]/[1-3tan^2A]
