I am a bicycle messenger in Edmonton, Alberta Canada. Tommorow the temperature is supposed to be -30 Celsius. Also it will snow and be a slow day. So to keep warm is it really a good idea to take a flask of scotch on route?
What would be the best alternatives as far as diet is concerned for maximum heat?

Tarzan (m = 85 kg) tries to cross a river by swinging from a 10-m-long vine. His speed at the bottom of the swing (as he just clears the water) is 8.0 m/s. Tarzan does not know that the vine has a breaking strength of 1000 N. Does he make it safely across the river? Justify your answer.

Create the equation that goes with the graph.
Ok, the graph looks kind of like this -|-.
The first point that lies directly on the X axis is located at (2,0)
The second point is located at (-2,-2)

Can someone PLEASE break this problem down into how I would be able to solve it. I'm desperate and my math grade is slipping. I have 5 other problems but I just need to know how to get started. Any help is appreciated

a friend of mine played a little prank on me and had me eat some organic morning glory seeds with him this morning as a snack, (i did not know it had any "good" qualities), my question is: are there any other legal plants you can think of with such qualities?

i have tried salvia, mushrooms, cacti extract and even a foxglove derived tea among other things. i would really like to know what else is out there.

True or False Questions:
1. All Square Marcrices Have Multiplicative Identities, T or F
2. Only square matrices have multiplicative inverses, T or F
3. Some square matrices do not have mutliplicative inverses, T or F
4. Some square matrices do not have multiplicative identities, T or F
5. All identity matrices are square matrices, T or F

I know some are repetitive, but if you could answer them all that would be so great =D
