according to the kjv pre-christian palestine was swarming with them (deut: 33:17; psalms 22:21 - lots of other places).

there aren't any unicorns in israel now (they'd be on the discovery channel if they were), not even any stuffed unicorns or unicorn skeletons.

did they evolve into a different species?

I just dropped a sealed bottle of vodka and the bottle rolled down the hill and stopped 25 feet from a pine tree. Unfortunately for me there is a big and angry dog chained by 50 feet long chain to a hook secured in the trunk of the pine.

As I tried to approach the pine, the dog immediately tried to attack me (thank god he is on the chain). All I can do is to walk at safe distance from the dog, while he closely follows me, barks loudly, and shows huge fangs.

Hi, hope someone can help with this basic physics question. I realise that the pressure of a liquid or gas is proportionate to changes in its volume and temperature. But does the actual volume of a gas or liquid ever change due to changes in its temperature or temperature,

Hi,

i got this curve:
x= (t^4)/4
y=(t^3)/3
z=(t^2)/2

And I'd like to find its norm at the point (4,-8/3,2) for t = -2

I know I can get the tanget to the curv, and there would be plenty or norms , but is there any specific one at that point ?

the first three terms of an arithmetic seris are (12-p),2p,(4p-5) respectively where p is a constant.
The value of p we've found...its part a)

but how many values of the series have a value of less than 400?

a)2p-(12-p) = 4p-5-2p
3p-12 = 2p-5
p=7

Dose anyone think that the great flood that was seen world wide in historical times could have been caused by a reduction in the earths gravity and could happen at some point again.and why not.

Do you think that watching Television as a child can greatly influence and bring on delusional states in adulthood such as being transpecies (otherkin - thinking they have a vampire/dragon/elves/unicorn spirit)? Also, belief in having "supernatural" abilities?

(Television emits a lot of different wavelengths of light, such as radiation; and if humans do have electromagnetic energy emitting from their bodies - can this mean that T.V. accelerates the psychic development of an individual, by their energy field absorbing mutagenic wavelengths of light such as radiation? Also, can the images from T.V. create an imaginery world for the individuals subconscious, images from T.V. being stored deep in their memory banks? Spiritualists (myself included) believe we have 7 major energy points (chakra's) in our bodies where we absorb and emit energy/light. Our 3rd eye chakra is called Ajna meaning 'Command' - so can T.V. develop delusional states?

Any extensive research done on this?

Hi, as part or a set of algebra questions from school, I have been asked

"Find the values of m for which the difference between the roots of the equation 16x^2 = mx - 2501 is 5."

I know how to use the discriminant to find the values that are real roots etc., but I have no idea how to work out the values in which the roots have a difference of 5.

The answers start with

"Let y, z be the 2 roots.
If ax^2 +bx +c = 0 then
y + z = -b / a
yz = c / a "
I have no idea what that means?
ANy hints would be appreaciated
