undeadknight26 · Answer

No its not buddy...undead army ain;t here...lets just answer the question :)

undeadknight26 · Answer

Well even though im not that type of guy this is quite an easy problem..all u have to do is make a equation for it...

anonymous · Answer

I need help setting it up!

undeadknight26 · Answer

Let me figure it out...give me a sec please :)

undeadknight26 · Answer

oh crap its a differential equation -_-
Didn't learn this yet...so let me call in the big guns XD
@SolomonZelman

anonymous · Answer

yes it is!

undeadknight26 · Answer

or @jdoe0001 :)

anonymous · Answer

just from definition, basically: P'(t) = 0.0135*P(t)

anonymous · Answer

could you work it out for me? :)

anonymous · Answer

I don't know how to do this.. I would like an explanation pretty please! <3

anonymous · Answer

The idea is that the rate of population growth is proportional to the population itself. They're telling you that the constant of proportionality is 0.0135. So, you write it like any other proportionality relation, using the derivative for the rate of change:
P'(t) = k*P(t) = 0.0135*P(t)
Does that make sense?

^^^ boss

anonymous · Answer

hmm

anonymous · Answer

So, say the population is at 1 million. Then it's growing at a rate of 0.0135*1000000 = 13500 people per year.

anonymous · Answer

then what?

undeadknight26 · Answer

then u watch anime and forget this stuff lol jk...

anonymous · Answer

Well, that's it - that proportionality relation is the differential equation.
