I would like the know what other metals in what percentage were used during this time pleeeease

Also .. had no idea which topic to put this under

c(sub n+1)=c(sub n) - f(c(sub n))/f'(c(sub n)) is the formula.

The Problem
Approximate the root of y=x^3+x^2-5, using c(sub 0)=1 as the initial guess.

I know the concept of repeating this process until the approximation becomes closer and closer, but I am confused as to what values you plug in where in the formula. Thanks for your help.

They also say one zero is 2, so one factor is (x-2)...I think....

Which of the following algebraic equations represents the following word problem.

The sum of three consecutive odd integers is 14 more than three times the 2nd integer.

x + (x+1) + (x+3) = 14 + 3(2x)

x + (x+2) + (x+4) = 14 + 3(x+2)

x + 1x + 3x = 14 + 3(x+2)

A + B + C = 14 + 3B

--I was told today that they found life in the Earth's crust recently (not the ocean crust mind you) where its deep enough that there was no chance of this material of being on the surface before. I hadn't heard anything of the sort, and can't find anything on Science website or the net in general. Is this kid lying or just doesnt know what he's talking about? He said in non-jargon terms its anarobic etc....
