Evolution is "the change in the inherited traits of a population from generation to generation" (http://en.wikipedia.org/wiki/Evolution). How does evolution account for the earliest functioning reproductive system? It could not have been the result of evolution, for this would entail a previous generation and it would no longer be the first reproductive system. It would have had to be the result of a non-evolutionary process. But that a non-evolutionary process would produce a reproductive, evolving, organism seems odd.

I am an atheist, so please no insults about religious dogma. I completely ignorant of evolution but I feel my question is still a valid one.

The general term of a series i tn=pi(3/11)^n+1. How many terms must be added to reach a sum that is greater than 0.32? The pi is the pi sign that equals 3.14....
This question is driving me nuts. the first term I get is larger than 0.32.

We are going to give a new layer of coating to the path. If one gallon of coating can cover 6yd^2 , how many gallons of coating do we need? Note that coating comes only by the gallon, so the number of gallons must be a whole number. (Use the value 3.14 for Pi .)

Find a possible formular for the ln(5(e)^(.3466x). Show your work.
Solve your formula for y.
Write your answer in the form y=ae^(kx) showing all steps.

For functions 2^x and 3^x, it seems that as delta x gets smaller, the average rate of change approaches a particular decimal. One of the decimals is greater than 1 and the other is less than 1. Using trial and error try to find an exponential function whose average rate of chance, using the intervals of 0.1,0.01,0.001, 0.0001, approaches 1. You should present at least 3 other exponential functions and their tables with the interval and average rate of change

-Not sure what the last question really means or how to do it.

Thanks
