Agata [3.3K]

Answer:

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

Explanation:

The law of uninhibited growth is given as:

A=A_o\times e^{k\times t}

A_o= 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

1300=1000\times e^{k\times 1 day}

k = 0.2623 day^{-1}

Population size of mosquitoes after 4 days

A_o=1000, k= 0.2623 day^{-1}

A =? , t = 4 days

A=1000\times e^{ 0.2623 day^{-1}\times 4 days}

A =2,855.36 ≈ 2,855 mosquitoes

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