The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1300 after 1​ day, what is the size of the colony after 4 ​days?

Respuesta :

Answer:

2,855 is the size of the colony of mosquitoes after 4 ​days.

Explanation:

The law of uninhibited growth is given as:

[tex]A=A_o\times e^{k\times t}[/tex]

[tex]A_o[/tex]= Original amount

A = Amount after time t

k = Positive constant repressing the rate of growth

We are given with:

Original population of mosquitoes = 1000

Population of mosquitoes after 1 day =1300

t = 1 day

[tex]1300=1000\times e^{k\times 1 day}[/tex]

[tex]k = 0.2623 day^{-1}[/tex]

Population size of mosquitoes after 4 days

[tex]A_o=1000, k= 0.2623 day^{-1}[/tex]

A =? , t = 4 days

[tex]A=1000\times e^{ 0.2623 day^{-1}\times 4 days}[/tex]

A =2,855.36 ≈ 2,855 mosquitoes

2,855 is the size of the colony of mosquitoes after 4 ​days.

Answer:

[tex]2855[/tex]

Explanation:

As per the law of uninhibited growth

Population after a time period of "t" will be given by

[tex]P(t)= P_0e^{kt}[/tex]

where,

[tex]P_0[/tex] is the initial population.

k is the growth rate

Growth rate of mosquitoes

[tex]1300= 1000*e^{k*1}\\e = 0.2623[/tex]per day

So, population of mosquitoes after four days will be

[tex]= 1000* e^{0.2623*4}\\=1000*2.855 \\= 2855[/tex]
