Scientists study ways to increase the population of wild salmon. How many salmon eggs may be needed to produce 18 adult salmon?
1 answer:
Answer:
Therefore, we conclude that is needed 72000 salmon eggs to produce 18 adult salmon.
Step-by-step explanation:
We know that scientists study ways to increase the population of wild salmon. We know that for every 8,000 eggs, only 2 adults may survive.
We calculate how many salmon eggs may be needed to produce 18 adult salmon.
Therefore, we get:
Therefore, we conclude that is needed 72000 salmon eggs to produce 18 adult salmon.

Answer:
Step-by-step explanation:
A second order linear , homogeneous ordinary differential equation has form .
Given:
Let be it's solution.
We get,
Since ,
{ we know that for equation , roots are of form
}
We get,
For two complex roots , the general solution is of form
i.e
Applying conditions y(0)=1 on ,
So, equation becomes
On differentiating with respect to t, we get
Applying condition: y'(0)=0, we get
Therefore,
