Another model for a growth function for a limited population is given by the Gompertz function, which is a solution to the diffe

krek1111 [17]

Answer:

The solution is

$P(t) = 1000e^{-1}e^{e^{-0.05t}}$ .

Step-by-step explanation:

We have the Gompertz's differential equation

$\frac{dP}{dt} = -cP\ln(KP)$ .

Notice that this a separable equation. So,

$\frac{dP}{P\ln(KP)} = -cdt$ .

Now, integrating in both sides:

$\int\frac{dP}{P\ln(KP)} = -\int cdt$ .

Recall that

$\int\frac{dP}{P\ln(KP)} = \ln(|\ln(KP)|)$ .

Thus,

$\ln(|\ln(KP)|) = -ct+A$ ,

and taking exponential:

$|\ln(KP)| = A'e^{-ct}$ .

Taking another exponential

$P(t) = \frac{A''}{K} e^{e^{-ct}}$ .

Now, let us substitute the given values for c and K:

$P(t) = \frac{A''}{3000} e^{e^{-0.05t}}$ .

To find the value of the constant A'' we use the initial condition:

$P(0) = \frac{A''}{3000} e^{e^{0}} = \frac{A''}{3000}e=1000$ .

Then,

$A'' = \frac{3\cdot 10^6}{e}$ .

Hence, the solution is

$P(t) = 1000e^{-1}e^{e^{-0.05t}}$

just olya [345]

So what you do is add 30 to 100 and then take away 10 leaving you with 120. You then multiply by 10 giving you 1,200 dollars a month. Wish I was making that much money a month :)

Leeza did this to solve an equation. Did she makes an error 4x=7+3(2x-5) 4x=7+6x-5

katrin [286]

Yes, there was a mistake in applying the distributive property. If you have to perform

$3(2x-5)$

you have to multiply both terms in the parenthesis by 3, not just the first one.

So, the correct expansion would be

$3(2x-5) = 3\cdot 2x - 3 \cdot (-5) = 6x-15$
