I understand that Evolution allegedly took millions of years. Considering new life is ushered into the world everyday, why don't we see it happening before our eyes?

Even though my profile says that I am a Christian, I am not looking for a heated arguement or insults. I am keeping an open mind - regardless of my beliefs. If you have some difinitive visual evidence of Evolution, please feel free to share.

Let f and g be functions that are differentiable for all real numbers x and that have the following properties -
(i) f'(x) = f(x) - g(x)
(ii) g'(x) = g(x) - f(x)
(iii) f(0) = 5
(iv) g(0) = 1

(a) Prove that f(x) + g(x) = 6 for all x.
(b) Find f(x) and g(x). Show your work.

A rock dropped from 1200 ft., ignoring air resistance. How long does it take to hit ground? How fast will it be traveling at impact? Would these answers change if it were thrown 90 mph horizontally? How far would the horizontal rock go before impact?

I have the 32 ft/sec^2. I just don't seem to be doing something correct. I think it hits at the same time. Then I just convert the 90 mph into sec for the first answer.
