I have two questions.

The first is 24=e(x+1).....where x+1 is an exponent. I know its very simple but i just can't remember how to solve it.

The second is log(4)x=3/2....where 4 is the subscript.

Any suggestions would be helpful.

In an article in the Journal of Management, Morris, Avila and Allen studied innovation by surveying firms to find the number of new products introduced by the firms. A randon sample of 100 California firms are selected. Each firm is asked to report the number of new products introduced last year. The survey found that on average, these firms introduced 5.68 products with a standard deviation of 8.70. Compute a 98% confidence interval for the new products introduced last year.

I am looking for scientific evidence to support this. The only thing I can find is by regular folks. Any scientific types have any information like NASA or something?

The Galaxy NGC 7742 is known to have a massive black hole in the middle of it.
So why hasn't the black hole swollowed the Galaxy? Why is gas able to shoot out from the Galaxy, I thought black holes were meant to suck things inwards, not push it outwards.

Do black holes start out as stars that collapsed on themselves or do black holes come about another way?

My 7 year old son is upset that the Sun is going to burn out in about 5 billion years and kill all life on Earth. I have attempted to show him how huge 5 billion is, but he insists that it is still too soon. He knows that moving to other planets or creating artificial worlds is a possibility, but he really wants to save the Earth. Does anyone have any ideas on how we could refuel the Sun when the hydrogen runs out? Or how about creating a new star to keep us warm? Or moving the planet to a new star? I know it is a big engineering project, but we have a long time to work on it.

Ok, I received an email about this and my daughter brought home a newsletter from school about it, so I was just wondering if it was true...

On Monday, August 27, 2007, two moons will rise in
the
midnight sky. Starting in August, the planet Mars
will be the brightest object in the night sky, and
will look as large as a full moon to the naked eye.
This will culminate on Monday, August 27th, when Mars
comes within 34.65 million miles of Earth.

Be sure to watch the sky on Monday, August 27th from
midnight to 12:30A.M. It will look like the Earth has
two moons.

***The next time Mars comes this close to Earth will
be in the year 2287.

Don't miss this once in a lifetime spectacular
event!!!

I have searched online and came upon this website that states it is all a host: http://www.snopes.com/science/mars.asp

So, what do you think?

Do you think moon landing was faked?...Probably another Nasa cover-up?...
just scroll down when you open the page..and compare the two photos of astronaut Aldrin facing the flag...

heres the link:

http://en.wikipedia.org/wiki/Apollo_Moon_Landing_hoax_accusations

The first photo shows that Aldrin is saluting the flag...then the second photo: Buzz Aldrin's hand is down, head turned toward the camera, the flag is unchanged.

Im just curios because if you compare the two photos, the flag is not waving..

O_o

I dont really care about nasa ufo cover-ups...My main concern was: is moon landing also a coverup?..weird..
