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.
Answer:
117
Step-by-step explanation:
Sum of all angles of pentagon = 540
x + 86 + 140 + 138 + 59 = 540
x + 423 = 540
x = 540 - 423
x = 117
Answer:
The ratio must be guaranteed.
Therefore,
18/6 =12/x
=> x= 6*12/18 = 4
