Step-by-step explanation:
a).
It is given that rate at which the population increases is directly proportional to size of the population. Thus we have,
It is given in the question that the population increases by 2% in one day. Now we know that the time in days is a continuous variable, so we have
2% of P =
b).
It is given that the population is harvested by 4 % in one day
(Since 4% of the P is harvested.)
c).
It is given that 1000 fish are being harvested or removed in one day.
d).
The threshold is given by
or
If you use the property of substitution, you can get (-2, 6.5) as your answer. Substitute the value of X (-2) in the initial equation and solve for Y.
Y= -3/4 (-2) +5 ( I am sure you inadvertently put the Y here also)
Y= 6/4 + 5
Y = 6.5
