Answer:
1) The size of the colony after 4 days is 6553 mosquitoes
2) After
Step-by-step explanation:
To answer this question you must use the growth formula
Where
is the initial population of mosquitoes = 1000
t is the time in days
k is the growth rate
N is the population according to the number of days
We know that when t = 1 and then N = 1600
Then we use these values to find k.
Now that we know k we can find the size of the colony after 4 days.
To know how long it should take for the population to reach 10,000 mosquitoes we must do N = 10000 and solve for t.
