I'm working on a chemistry assignment that involves creating redox tables. The explanation in the textbook isn't a very good one and I can't find my answer through google either :mad:
Here's the problem:
The following equations represent spontaneous reactions. From this evidence, set up a...
I need help with a projectile motion problem I'm working on. I completed the problem, but I'm not sure if I got it right and there's no one that I can confirm my answer with... except you guys :smile:
A ball is thrown at an angle of 37.1* above the horizontal from a point on the top of a...
A boat leaves dock at 2:00 PM, heading west at 15 km/h. Another boat heads south at 12 km/h and reaches the same dock at 3:00 PM. When were the boats closest to each other?
I've solved other problems similar to this one, but I can't seem to figure this one out. I'm not sure what I have to do...
I have a problem that I need help with. I tried to solve it, but I don't know how. I don't have much trouble solving simpler min and max problems, but when they start throwing in more numbers, I get confused.

I need help with a question asking if the particle is speeding up or slowing down.
A particle moves on a vericle line. It's position, s, in metres at t seconds is given by s(t)= t^3-9t^2+24t
a) determine the velocity and acceleration functions
I got v(t)= 3t^2-18t+24 and a(t)= 6t-18
b)...
I need help finding limits. I know it's pretty simple most of the time... I know that for example if the lim x--> 3 of x-3, you just plug 3 for x... what do I do if it's the absolute value of x-3?
I know you guys like to see that I've tried to solve the problem, but there's not much I can...
Today was the second day of school, and my calc teacher gave some review homework. We did problems similar to the ones last year, but I don't remember how to do them. I'm sure it's pretty simple, but I need help anyways :rolleyes:
It says:
Expand and simplify. Express each equation in...
If I am given (y-2)2= 4 (x-3), how would I find the vertex, equation of the axis of symmetry, and the direction of the opening? I'm guessing that I have to use PF=PD, but it's confusing because it looks different from other things that I have done involving PF=PD.
Thanks.
I completed a question about TIR in a glass prism, and I was wondering if someone can tell me if I got it right. Thanks
"Less" and "more" refer to the less dense medium and more dense medium, and the red line is the normal.
