Each number needs a letter! Any amount you do is fine.

1)weight
2)physical properties
3)hydrogen
4)grams per cubic centimeter
5)exothermic
6)mass
7)fourth phase of matter
8)volume
9)molecules
10)endothermic

A. amount of matter in an object
B. plasma
C. effect of gravity on mass
D. release of energy
E. particles of matter
F. absorption of energy
G. gas that is combustible
H. density
I. graduated cylinder

hello everybody i got this problem at school that i am like half way into figuring out but i am stuck and i would realy appreciate your help
here is the problem:

A British Concorde(BC) and a French Concorde(FC) flew in opposite direction around the world, a distance of 40 000km. The BC covered half of its flight distance at a speed of 2500 km/h and the other half at a speed of 1000 km/f. The FC spent half of its flight time at 2500 km/h and the other half at 1000 km/h. Which concorde completed the trip first, and by how many hours did it beat the other?

thanks alot for any help

I just wanted to check my answer to anyone who's willing to answer it... (PS an explanation would be extremely helpful!!)

Identify the domain of the function give by g(x) = [Square Root of (x+1)] all divided by (x^2 +4x +5) .
What if anything can you deduce about the range?

Hi, I am an undergraduate computer science/software engineering major who has an interests in AI (especially anything concerning artificial general intelligence). I am particularly infatuated with research and theories concerning creating an AI with capabilities similar to those of a human (which I realize is a LONG ways off in the future). But I do like AI in general from what I have read.

I already do a lot of reading and researching on AI, but it is usually just me aimlessly floundering for things concerning the topic. I would like to know how to REALLY get started learning about AI as a discipline. What are the fundamentals? Foundational theories and anything else I need to get started (apart from what I will inevitably learn in my undergraduate studies, I want to learn about the things that I might be taught in grad school if I can or anything else of interest)?

Thanks for your time.

How do you solve:
angle AOC = 7x-2, angle AOB= 2x+8, angle BOC= 3x+14
And it says to solve for x, but how am I supposed to do that with three of them and nothing to set them equal to? Thanks.

The figure below shows an electron entering a parallel-plate capacitor with a speed of v = 5.55 *10^6 m/s. The electric field of the capacitor has deflected the electron downward by a distance of d = 0.602 cm at the point where the electron exits the capacitor. (the length of the plate is 2.25cm)

(a) Find the magnitude of the electric field in the capacitor.
N/C
(b) Find the speed of the electron when it exits the capacitor.
m/s

I am taking a chemistry class towards my BSN and the instructor posed a question to us before the end of class last week and it was: What is the correlation between the boiling point of water and the properties of a bullet proof vest? I have searched on yahoo and found something about intermolecular changes but I want an expert on the subject to help me out it was not an assignment but I just want to impress the instructor with the correct answer. Thanks in advance.

Ramon delivers packages for his job. He visited his work and picked up "some" packages. His instructions were to drop off 1/2 of those packages at a second building and pick up two more packages. His third stop he dropped off 1/2 of his packages and picked up seven. His fourth stop he dropped off 1/4 of his packages and picked up one. On his fifth stop he left 1/2 of his packages and picked up one. On His last stop he dropped off 6 packages, thats all he had left. Then he took lunch break. How many packages did Ramon deliver before lunch? Please leave order of steps you took to receive your answer.

I have a trigonometry quiz tomorrow. We aren't allowed to use a calculator, just our unit circle which has degrees, coordinates, the location and numbers such as 5pi/6.

How do you find Sin, Csc, Cos, Sec, Tan and Cot using this unit circle? Thanks!!
