Everyone knows that the moon has no air because it doesn't have enough gravity to hold it. Does that mean the smoke from the Lunar landings has already drifted off to space?

Is most of the stuff in what the bleep do we know, just theory, or is in fact a proven thing that, superpositioning, we never touch anything, and entaglment that were all connected, law of attraction, and all that theory they tell us as its true,

And also how can they say an atom is empty space with a charge if there are subatomic particles inside of them that are real matter and not empty space/./....... i think they better rethink what they say...

i am having trouble believeing it all....

A curve has the equation: y=x^4 - 8x^3 + 16x^2 +8

a)Find dy/dx and d2y/dx2
b)Find the three values of x for which dy/dx = 0
c)Determine the coordinates of the point at which y has a maximum value

i'm having real problems with part B, through trial and error i managed to find two of the values for x (0 and 2) but the last one i can't seem to find, i would appreciate it if you would pote your working out also. Thanks!

Sally is a surveyor in the badlands in South Dakota. At point A on the south side of a deep canyon, she sights across to a fire tower on the north side of the canyon at point B. Then she moves a measured 500 feet along the south rim of the canyon to a point C on a line perpendicular to her original sight line AB. Setting up her transit again, she finds that her line of sight, CB, to the tower is 87 degrees. Correct to the nearest whole foot, how far is point C from the tower?
