Math, Please help!
I'm having a hard time in math, and every time I start my test my eyes glaze over. Can anyone please help me out? (9m+6)+(-5m-6) (3r^2+7r+1)+(4r^2-8r-2) (6h+1)-(9h+4) (-7w^2-2w-1)-(-5w^2 +3w-2)

I managed to get it :) though for others who might be looking to solve this for their practice questions Convert Kb to Ka Ka = kw/Kb then just use an ice table with Ka=x^2/ 0.300M-x (x is small) and just -log[H3O+)

Physics
Ok... but I still don't get it... Is there a formula type thing that could help me?

Physics
Yes - if it is the same person answering it - it is me again! My question has STILL not been answered... How would I solve for upwards acceleration with this kind of image, assuming mass and force are given.
December 6, 2009

Physics
How would I go about calculating the acceleration of a mass being pulled up an inclined plane at an angle. Given - mass, and presumably angles So the object is being pulled up an angle at another angle.
December 6, 2009

Physics
But what about the second angle? There is another one besides theta that I don't know what to do about - but that explanation just helped alot with all the other problems!

Physics
Compute the net force along the direction of the plane, making sure to subtract friction (if any) and the component of weight along the plane (W sin A). -That is the part that I don't get how to do...

PreCal. What is the difference between the equations (n(n+1))/2, and n/2(ti+tn)?? Under what conditions would you use them? Thanks much!!!

proof by mathematical induction
subject is PreCalulus. 2^(k+3) = and < (k+3)! i know how to do proving using mathematical induction when its just an equal sign, but I dont understand what to do when its an inequality. thank you!!! Here is what I would do Step 1: check if it is true for k=1 that is: let k=...

Math
What is quantity and how do you use it. A quantity is how much you have of a particular quality or substance. You can use it to compare to other quantities to see if they are more or less. Depending on what you desire — more or less — you might adjust the situation...
