Science & Mathematics - 2 December 2006

Here it is- "You are confronted with the following formula:

A * [(B + C)(D - E) - F(G*H) ] / J = 10

Knowing that each variable is a unique, single-digit, nonzero number, and that C - B = 1, and H - G = 3, what is the number ABCDEFGHJ, where each letter is a digit? For example, if A = 4, B = 2, and C = 7, ABC would equal 427."


I will greatly appreciate it if ANYONE can find this answer!

(Let X be the angle subtended horizontally by Emma's view of the bridge).

A. Write a formula for Emma's distance from the bridge,d, as a function of X.

B. Write a formula for X as a function of d.

C. Evaluate the formula in part (B) for d = 500, and interpret the result in the context of the problem.

I'm in desperate need of help with this problem. I can't find the position of where Emma is located and need someone to show me how to solve A, B and C in detail.

Like since the Scientific method states observation, and since no one was there, according to evolution, how can science say anything about the origins.

The Bible is based on eyewitness accounts and has been proven historically accurate. It cannot be proved wrong by science and various things within it such as the flood, better explain and fit with what we observe on earth.

(now here are the rules, if you don't have anything good to say don't say anything,)
don't criticize others who made an earlier question.
I want to know what you think about the question, not what you think about the other members of this site.

The most basic law of thermodynamics states that energy can neither be created nor destroyed: http://en.wikipedia.org/wiki/Energy.

Since it is obvious we all have body energy to do work, what happens to this body energy once you die since it cannot be destroyed nor created??

(please don't give me a dumb answer like static electricity or anything like that)

alright, I am trying to factor and simplify this expression: 81x^2-144y^2
-this would be difference of two squares
-A^2-B^2=(A+B)(A-B)
** i got, (9x+12y)(9x-12y)
- should I factor it further than this or am I done???

okay i am a senior in high school and i am interested in either zoology or ecology, but i can't really decide which. Does anyone know a zoologist or an ecologist that i can talk to through email that could help me in knowing what they do everyday, what they're paid, and other general information about their career field and job.
