Step-by-step explanation:
Given:

Find: values belong to the solution
Explanation:

and

so those values are solution which is x<12
i.e; x=4 and x=11
Answer:
(a)
(b)5,832 Mosquitoes
(c)5 days
Step-by-step explanation:
(a)Given an original amount
at t=0. The population of the colony with a growth rate
, where k is a constant is given as:

(b)If
and the population after 1 day, N(1)=1800
Then, from our model:
N(1)=1800

Therefore, our model is:

In 3 days time

The population of mosquitoes in 3 days time will be approximately 5832.
(c)If the population N(t)=20,000,we want to determine how many days it takes to attain that value.
From our model

In approximately 5 days, the population of mosquitoes will be 20,000.
The distance between two points is found using something called the distance formula. The distance formula goes like this:

(x₂ - x₁) and the y equivalent is the same as the change between the x or y values between each coordinate. Using this formula, the distance between (5,-8) and (53,-28) is ~43.635
