A bee farm has 700 bees on September 1st. Winter is coming and the number of bees decreases 35% every 2 months from September 1st until March 1st. How many bees are on the farm on March 1st?

Respuesta :

Answer:

[tex]P_t\approx 244 \ bees[/tex]

Step-by-step explanation:

-The bee's population follows an exponential decay of the form:

[tex]P_t=P_oe^{-rt}[/tex]

[tex]P_t[/tex] is the population at time t

[tex]P_o[/tex]  is the initial population size

[tex]t, r[/tex] is time and rate of decay respectively.

#We substitute and solve [tex]P_t[/tex]:

[tex]t=6/2=3\\\\\therefore P_t=P_oe^{-rt}\\\\=700e^{-0.35\times 3}\\\\\\=244.96\\\\\approx 244\ bees[/tex]

-Since it's a decay, we round down any fractional amount in the population.

Hence, the population after 6 months is approximately 244 bees

Given the rate of decline of the populatiaon of the bees, the number of bees on the farm on March 1st is  192 .

How many bees are on the farm?

The formula that can be used to determine the number of bees on the farm is:

FV = P (1 - r) nm

  • FV = Future value
  • P = Present value
  • R = rate of decline
  • N = number of months  = 6/2 = 3

700(1- 0.35)^3 = 192
