Is there anyone who can help me?
I was bothered by the negative occupation in atomic orbital like 5p here.
I don't understand what it means. By the way, 6.00 here is the total number of charges.

"Suppose that a certain population satisfies the initial value problem
\frac{dy}{dt}=r(t)y - k, \qquad y(0)=y_0
where the growth rate r(t) is given by
r(t)=\frac{1+\sin t}{5}
and k represents the rate of predation.
(a) Suppose that k=\frac{1}{5}. Plot y versus t for several...
A bacteria culture starts with 300 bacteria and grows at a rate proportional to its size. After 3 hours, there are 9000 bacteria
A.) Find an expression for the number of bacteria after t hours. for this part, i got 300*e^{1.133732*t}
B.) Find the number of bacteria after 4 hours. well...
The population is increasing but the sum total of money remains the same. Is it inevitable that there will be more people than the limited amount of currency can supply for?
The population of the wolves influences the change in population of the mooses. When the population of the wolves increase, the mooses' population also increase. From the population growth formula of the wolves
delta N/delta t = rN(K-N)/K
which factor affects the population of the mooses...

Hi everyone
I'm having trouble with this problem, while preparing for my calculus test this Monday...could anyone help me figure out the solution...I know that I must use the formula P=P(original)e^kt where...
Alright, my teacher the sadist gave us an assignment over the holidays, and so far, everyone in my class has gotten all but this.
The equation is representative of the population growth of fish in a fish pond.
p= m / 1+ae to the -kt
p is the intial population, m the carrying capacity...
Solar energy flux, Earth's population...
Hi everyone :smile:
I have this one question from my optics course that has me totally stumped. It reads "Solar energy flux at Earth's position is about 1.7kW/m^2. Estimate the maximum possible population of the Earth."
I've looked through my...
) IF the rate of increase o f population of a country is 3 percent every year, by what factor does it increase every 10 years? What percentage increase will double the population every ten years?
***N= Pe^(k*t) <---this is the equation, not sure how to use it...
there is a definite risk that in the following century human population may increase to above 18 billion (it is 10 billion right now, isn't it?) with maximum increase in the third world and slight decrease in first world. do you think human society can deal with such population demographics...
The following question is from a textbook..and I can't seem to solve it. Can someone help.

The population of a midwestern city follows the exponential law. If the population decreased from 900,000 to 800,000 from 1993 to 1995, what will the population be in 1997?
