Take the antiderivative of e^(pix^2) from the interval negative infinity to positive infinity. REMEBER: SOLVE THE INTEGRAL NOT ANTIDIFFERTIATE IT. YOU CAN REASON THIS OUT WITHOUT ANY ACTUAL CALCULATION.

Louis and Boris are good buddies. Their problem is that Louis is only 1 foot tall, but Boris is 6 feet tall. On January 1, 1800, Louis takes a magic potion that will make him grow 4 inches taller every year. He will grow at a constant rate until he is the same size as Boris. On January 1, 1800, Boris takes a magic potion that will make him shrink 12 inches every year. He will shrink at a constant rate until he is the same size as Louis.

1) On what date will they be the same size? Month, day, year.
2) How tall will they be when they are the same size?

If the human neing is at the top of the evolutionary chain according to the scientists and we cannot get any better or more advanced, then wont in theory, the rest of the beings in the universe be the same as us? And they will have to live on the only planets that are inhabitable A.K.A. another Earth-like planet which has to be the correct distance from their sun depending on the suns size and how much heat it gives off. So i think that unless there are more than 1 planets in the same orbit around a sun in a solar system, there will only be 1 planet in a solar system that can be inhabited.

I have heard that ancient sharks had 6 gills slits and modern sharks have only 5. But in pictures that I have seen online, all the pictures of prehistoric sharks have only five and the only one i can find with 6 is a modern shark called a Sixgill. Please help me because I need it for research for an art project.

Assuming the “Big 4” must be matched straight to be considered a win, the probability of winning would be (10^4) 10,000 to 1 (or 1 in 10,000).

If the bet $100, the payoff is $5,000:
The expected value of winning is:
Winlose
Gain X$4900-$100
P(X)100/10,0009900/10,000

E(X)=$4900*100/10,000 + (-$100)* 9900/10,000
=49+(-99)
= -50

Because the expected value of winning the game is negative, it is in favor of not winning (in favor of the house). Meaning that for every $100 spent, the player will lose $50. I don’t think it is worth taking the chance.

Gain X$4900-$100

I read an article recently in the National Geographich that explained why Darwin got it right. I also read Richard Dawkins' "River Out Of Eden". Although I believe in creation, I tried to read these as objectively as possible. It seemed to me that they did not present a successful case. Although each presented a specific argument within the overall case that seemed persuasive, it was on a scientific matter that I only understood a little. These specific points did make me stop and think, though. Unfortunately, I can't actually remember what they were. Many of the arguments presented in each document could be successfully countered. If Evolution is true, why is the evidence not of such a high quality? I think evolutionist have generally not presented their case very well, but what do you think?
