A bird species in danger of extinction has a population that is decreasing exponentially (A = A0e^kt). Five years ago, the popul
Natalija [7]

Answer:

It'll take approximately 34 years from today.

Step-by-step explanation:

in order to solve this problem we first need to find the rate of change, "k", to do that we will use the given information where the population was 1400 five years ago and its now 1000. Applying this data to the equation gives us:

A = A_0*e^{k*t}\\1000 = 1400*e^{5*k}\\1400*e^{5*k} = 1000\\e^{5*k} = \frac{1000}{1400}\\ln(e^{5*k}) = ln(\frac{1000}{1400})\\5*k = ln(1000) - ln(1400) \\k = \frac{ln(1000) - ln(1400)}{5} = -0.06729

We now know the value for "k", we can estimate how many years it will take for the bird population to dip below 100. We have:

100 = 1000*e^{-0.06729*t}\\e^{-0.06729*t} = \frac{100}{1000}\\ln(e^{-0.06729*t} = \frac{1}{10}\\-0.06729*t = ln(0.1)\\t = -\frac{ln(0.1)}{0.06729} = 34.22

It'll take approximately 34 years from today.

There can be 18, 12, 9, 6, 4 , 3 or 2 students on each team depending on the number of teams selected.

<h3>How to know the number of students on each team?</h3>

Considering there are at least 2 teams but no more than 19 teams, let's calculate the number of students in each case:

  • 2 teams:  18 students per team (36/2 = 18)
  • 3 teams: 12 students per team (36/3 =12)
  • 4 teams: 9 students per team (36/4 = 9)
  • 6 teams: 6 students per team (36/6 = 6)
  • 9 teams: 4 students per team (36/9 = 4)
  • 12 teams: 3 students per team (36/12= 3)
  • 18 teams: 2 students per team (36/18 = 2)
