Imagine a chess board. Put a wheat grain in the first square, then two on the next. Double the amount of grains on each of the following squares. (example: 1, 2, 4, 8, 16...) How many wheat grains will you have in total when you finish filling the 36 squares whith the double amount of grains that you have in the prior square? (in total, how many grains will you have on the board?)

Three people go to a hotel. The bellboy charges them $30 for the room. Each of them pays $10. After they go to their rooms, the manager tell the bellboy that the room only costs $25. The bellboy takes the change and decided to keep some for himself. He gives $1 back to each of the people, and keeps $2 for himself. So each person paid $9 for the room, which means they paid $27 total. And the bellboy has $2. But 27+2=29. So where is the missing dollar?

This is a fun little question. If you've heard this before, don't answer.

Two integers, m and n, each between 2 and 100 inclusive, have been chosen. The product, mn, is given to mathematician P. The sum, m + n, is given to mathematician S. Their conversation is as follows:
S: "I know that you don't know the sum."
P: "Now I know the sum."
S: "And now I know your product."

What were the numbers?

The period, T, of a pendulum is given in terms of its length, l , by

T = 2phi(l/g)^1/2

If I find the sign of dT/dl is positive then what does this tell about the period of pendulums???

Need answer right away, thanks

I got stuck on this problem, maybe someone can give me a hint

Let (X, M , m) be a measure space and let (f_n: X --> [0, oo]) be a
sequence of functions that converges to a function f. Suppose that lim (\Integral(over X) f_n dm) = \Integral(over X) f dm < oo. Then, for every set E in the sigma-algebra M, we have lim (\Integral(over E) f_n dm) = \Integral(over E) f dm. Show that this conclusion may fail if \Integral(over X) f dm = oo.

If lim (\Integral(over E) f_n dm) = \Integral(over E) f dm is not true, then it's not hard to show that there's a subsequence (f_n_k) such that lim (\Integral(over E) f_n_k dm) < \Integral(over E) f dm, but I don't see why this leads to a contadiction.

Thank you

Two vectors lie with their tails at the same point. When the angle between them is increased by 20degr. the magnitude of their vector product doubles.
The original angle between them was about:
a 0
b 18degr
c 25 degr
d 45 degr
e 90 degr

I drew pictures for all answers and I think only 0 degr would work but I'm not sure. How can I calculate this?

If identical guns fire identical bullets at the same speed from the same height above level planes, one on the earth and one on the moon, what is true:
1 the horizontal distance travelled by the bullet is greater for the moon.
2 The flight time is less for the bullet on earth
3 The velocities of the bullets at impact are the same

I think 1 and 2 are true but what about 3?
I don't think it's true because if I would calculate V, I would have to use g and for the moon that's 1.63m/s making the result different than the result we would get on earth using 9.8m/s.
Who can explain this to me please?

1. Base case n = 4
4! = 24
2^4 = 16
24 > 16

2. Assume n!>2^n. Prove (n+1)!>2^(n+1)
n! > 2^n
2*(n+1)n! > (n+1)(2^n)*2
2(n+1)! > (n+1)2^(n+1)
2(n+1)! > 2^(n+1)

This is where I am stuck - I can't figure out how to get rid of that two on the LHS. Any help would be appreciated.

On the table there is a 5-liter jug full of grape kool-aid. There is also an empty 2-liter jug and a empty 3.5 liter jug. You can pour the kool-aid back and forth between the jugs, but you can't add any of the "grape deciciousness". How can you end with 2.5 liters in both the 6-liter and 3.5-liter jugs?


THANKYOU FOR HELP!!!!!!
