Making Equations to Solve a Problem----HELP, PLEASE! Homework Statement Hi, I am in dire need of your help. I can't seem to solve this problem: Here's my trial on this: 7h+11e= martians 1/2(7h+11e) +1/2=295 eyes 1/2 + 1/2(7h+11e)= 410 heads Then do the subtraction method from...

Consider the following equilibrium: CO(g) + 2H2(g) <-> CH3OH(g) Some CO, H2 and CH3OH were placed in a 1.0L container. When equilibrium was established, the [CO] had increased. Which of the following is true? A. Trial Keq > Keq so reaction shifted left to reach equilibrium. B. Trial Keq < Keq...

Homework Statement \int_0^3\ (t-2)^1/3 Homework Equations Second of Fundamental Thereom of Calculus The Attempt at a Solution I don't know what to do first because I'm not used to questions with square roots. Once someone help me with the beginning, I can probably...

OH! Thanks for that. Problem solved.

OH! Thanks for that! But, the thing is.. the answer for the critical number is -1/3 and from looking at the first derivative, one of the critical point is -1/2. So what am I doing wrong?

I'll be right back. I'm at school right now and bell is going to ring soon. Thanks for the replies, I'll look into it once I get home.

Simple Math-- Need help =/ [b]1. Homework Statement [/b I am confused on how this equation: 2h + (16/h-8 +2) (-8/(h-8)^2 is simplified to this equation: 2h - 128 (h-8)^3 - 16/(h-8)^2 Homework Equations Simplifying skills. The Attempt at a Solution Well, I know that they got the...

HAHA. Thanks. That's all I needed to know. You've solved one of my many problems, AGAIN! THANKS!

What I meant by equal the equation to one was that getting the derivative of the equation and equalling it to 1. 1 = 3x^2 -8

I found out the tangent line is at (3^1/2, -13.66) which is parallel to the secant line through (1, -12) and (4, 27) Now, I don't even know if that helps.. but there it is. Lol!

Hm.. I just realized it and I'm stuck. I don't know what to do or what I'm trying to get.. HAHA On the bright side, I do have the C value and the value for (f(b)-f(a))/(a-b): (f(b)-f(a))/(a-b) ( 27 + 12 )/(4-1) = 13 C value = x^3-8x-5 f' = 3x^2-8 3x^2-8 = 1 3x^2 = 9 9 / 3 ^1/2 = 3^1/2...

Yeah, apparently my drawing was a mess. You can try my other question below this topic. =)

Homework Statement Given the function f(x)= x(x^2-8)-5 satisfies the hypothesis of the Mean Value Thereom on the interval [1,4], find a number C in the interval (1,4) which satisfies this thereom. Homework Equations f'(c) = f(b)-f(a) / b-a The Attempt at a Solution 1) Expand...

OH, THANK YOU! Problem solved. =)
