Differential Equations
If a population grows continuously at a rate of 8% per year, which of the following represents the population as a function of time t, given an initial population of 5000?
P(t) = 5000e^{0.08t}
P(t) = 5000 + 0.08t
P(t) = 5000e^{8t}
P(t) = 5000e^{0.08}

will eventually approach a limiting value regardless of .
The solution represents a linear function when .
If is proportional to , the graph of would be parabolic.
If the population of a species growing according to the differential equation , what is the expression for the population at time if there were initially 200 individuals?
The solution to the differential equation with an initial condition is given by:
Given an initial condition for a model , where P represents population at time t, what does K represent?
Carrying capacity of the environment for the population
Exponential growth rate without environmental limitations
Rate at which new individuals are born
Initial size of the population at time t=0
Given a population that grows at a continuous rate of 3% per year, which of the following represents the rate of change of the population at any given time t?
In setting up initial conditions based on a problem involving a population modeled on a logarithmic scale according to the equation , under what circumstances might issues arise regarding N's ability to remain fully functional in terms of ensuring the ongoing validity of those sam...
Whenever external interventions distort regular progression cycles, undermining the integrity of the foundational elements crucial for supporting the long-term viability initially established in the presets.
When N becomes equal to the baseline comparison term , complicating things logarithmically-wise and relationless from an overall perspective of the effectivity designated by the outset norms.
When outward forces exceed the inherent natural repopulation rates, thereby forcing a revaluation of the base figures previously regarded as static environmentals.
During phases of rapid expansion or depletion that surpasses the ability of the systems to compensate accordingly, making it imperative to reassess the grounding benchmark indices.

If the population of a species grows according to the exponential model , where , what is the limit of as approaches infinity?
The population will decrease to zero.
The population growth rate will approach zero.
The population will stabilize at a certain carrying capacity.
The population will grow without bounds.
The size of a certain fish population modeled by the differential equation , where N is the fish population, a and b are positive constants. If b increases while the number of fish remains the same, which of the following correctly describes the relation between and the population growth rate?
Neither increase nor decrease has a direct proportional relation to fish population growth rate
For any value of b, increasing it will always result in a rapid increase in growth
As b increases, the growth rate decreases, provided that N does not change simultaneously
b has no effect on the growth rate, since the population number remains constant
Which of the following represents the solution to the differential equation ?
y = C(0.02x)
y = e^{0.02x}
