Step-by-step explanation:
Add the parenthesis and then multiply it to the cost to get the answer
With cross multiplication you can find that they are the same. In both equations, x would be 100.
Answer:
a. The population does not become extinct in finite time.
Step-by-step explanation:
The model for the population of the fishery is

If we rearrange and replace the constants we have:

Now we can calculate if the population become 0 in any finite time

To be a finite time, t>0

We can conclude that the only finite time in which P=0 is when the initial population is 0.
Because P0 is a positive constant, we can say that the population does not become extint in finite time.
