Is meditative travelling in time and space the same as travelling through worm holes where time-space fabric is distorted to an extent that two distant points meet each other and once can simply step into another time-space ?? Is it that yogis/meditators use mental powers to distort time-space fabric and thus travel back and forth in no time ??

or at least just the space traveler people.

A guy rides south on his bicycle in a straight line for 15. min. with an average speed of 12.5 km/h, how far has he ridden?

Distance=12.5 km/h/15 min.

12.5 km/h / .4 hrs.
Distance equals 3.125 kilometers right?

I was just browsing information on Hurricane Isabel, which I had the thrill of confronting in 2003 (seriously--check out http://www.jesusfreak.com/isabel.asp ) and got to wondering, what has been the farthest north and farthest south hurricanes have gone in the Northern Hemisphere? I'm no meteorology expert, but isn't it theoretically impossible for a hurricane to cross the equator?

The following is a problem I have to program for MATLAB; my math skills are not the best though, so I would appreciate any help:)
A box has the dimensions of 5 inches x 4 inches x 6 inches
I must: compute the length of the diagonal from one corner to the far corner of the box. Also, if you know what this is called, it might help because there is possibly a program in MATLAB that already does this function.... Thanks in advance!

Examples

A veggie burger is better for you than a beef one but the beef one is so tastes so much better

Fried chicken is bad for you but it tastes better than baked chicken

plain veggies are better for you but butter makes them taste better

I know these are probaly not the best examples but I thin k you see the point.

Why?

Suppose the first rock in Conceptual Checkpoint 2-5 drops through a height h before the second rock is released from rest. Show that the separation between the rocks, S, is given by the following expression:
S=h+(square root of (2gh))t
In this result, the time t is measured from the time the second rock is dropped.

The vacuum compartment inside of a thermos would probably have atotal exposed area of about 1square ft. The amount of atmosphereic pressure on 1sq ft would be about 1000lbs! But when i looked inside of my thermous it apears to be just a relatively thin set of glass jars.

Why doesn't the atmosphere shatter it?

ALso, i saw on mythbusters that they have a big vaccum chamber and the clear door on it is about four inches thick! Why the difference?

I've heard we live in 3 dimensions but there are more possibly up to 10 different dimensions and I would like to know exactly what that means.
Does it mean three sides to everything or 10 sides to everything?
What does it mean?!!!!!

A business woman is preparing an itinerary for a vist to six major cities

a) How many different itineraries are possible?
which is easy, 6!

b) If the businesswoman randomly selects one of the possible itineraries and Denver and San Francisco are two of the cities that she plans to visit, what is the probability that she will Denver before San Francisco.

I have the answer, I just did [(5! x 1) + (4 x 4!) + (12 x 3!) + (24 x 2!) + (4!)] / 6!

Now my question is, is there a more elegant way to extract the same answer?

Hi, I just started statistics and I would really appreciate some help with this practice problem.

Some information from 20 students was gathered about a workshop.
One of the items listed says 'Duration: 6 weeks'.
Would this be quantitative or qualitative data?
If it is quantitative, then would it be discrete or continuous?
Thanks so much.

1) Find the constant c that makes g continuous on (-infinity, infinity)
g(x) = {x^2-c^2 if x<4
{cx+20 if x>(less than or equal to)4
I got: by plugging in 4 into both equations
x^2-c^2=4^2-c^2=16-c^2 & cx+20=c(4)+20=4c+20
then combining them together: 4c+20=16-c^2
4c+4=-c^2
c^2+4c+4=0
(c+2)(c+2)=0
c+2=0
c+2=0
c=-2 & c=-2

2) Use the intermediate value theorem to prove that there is a positive number c such that c^2=2. (This proves the existence of the number sqrt[2])
c^2 is a polynomial & continuous function on its domain & its domain is from (-infinity, infinity)
It's an open interval so I took a closed interval of [1,2] from that open interval.
f(1)=1 & f(2)=4 so N=2 so there exists a number c in (1,2) such that f(c)=2

<1 and <2 are complimantary angles. Find the measures of the angles when m<1 = (x-10) degrees and m<2 = (2x + 10)degrees.

Are the two angles equal? I am so confused. What's the answer?
