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.

Answer:

2855

Explanation:

As per the law of uninhibited growth

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

P(t)= P_0e^{kt}

where,

P_0 is the initial population.

k is the growth rate

Growth rate of mosquitoes

1300= 1000*e^{k*1}\\e = 0.2623per day

So, population of mosquitoes after four days will be

= 1000* e^{0.2623*4}\\=1000*2.855 \\= 2855
