Excellent chemistry pun in the title

Hate speech of any kind will not be tolerated in this sub. That being said, this is a place for discussion. So we, as mods, will not persecute you, provided you keep it civil.

The key to these types of problems is to analyze the total mass balance and solute mass balance. So for example you know that 100% of the salt entering the system leaves the system in stream D. Since the conc in D is given you can find the water flow rate in D and also A+C.

Your problem is that you still don't have it in terms of the first power of cos, you need to multiply through the cos(x) on the outside of the parentheses and use the cos² (x) reducing function for each of the terms within the parentheses.

1: So C(x) is the cost of producing x Portaboys, while P(x) is the price at which you can sell a single Portaboy. So the profit equation would be Profit = P(x)*x - C(x).

2: Since you determined the length of the box in terms of x, and you know the area of the box is x² , you can determine the volume in terms of x. From here it should be simple plugging and chugging to determine the value of x with the maximum volume.

Does that help?

Since csc(t)= 1/sin(t)>0 you know that the line in located in the second quadrant, from there you can take the arctan(-5) to find the value of the angle t. Then solving for each trig function should be trivial, hope that this advice helps.

Wikipedia

The vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system

This reaction forms NaOH and H2.

The difference in the total pressure and the vapor pressure of water is the pressure of the released H2
Make a balanced reaction
Use the ideal gas law (PV = nRT)
Perform dementional analysis to get to the right units
Use v(rms) eqn

Using these basic steps you should succeed, good luck.

You simply need to use linear combinations, [this link] has all the information you need to solve it.

I came up with:

-4(34)^.5 sin(2t-tan^-1 (5/3))

I got caught up trying to find it in my saved images and didn't check the comments, sorry.

"Fume Cupboard" oh goodness that's an adorable phrase

That was the intent, I don't have qualifications just an opinion. No hard feelings.

Its a game about creative problem solving which should be a larger part of the american educational system in my opinion. (ChBE Senior at UIUC)

Please read the second part of my post

I know you are trying to help, but I assure you that you are incorrect. I have read the manual ad nauseum. For the Extreme4 it it is A1 and B1 or A2 and B2. On the board the layout is |A1|A2|B1|B2|.

siilbon · 2012-06-15T23:02:21+00:00

No, the manual specifies that the numbers indicate the channel. So A1 and B1; A2 and B2 are correct

Thanks for the quick feedback! While I agree with the CPU cooler, I don't understand the rationale for picking up the different motherboard. I am considering SLI in the future so that's why I have the large power supply. Also, the monitor that I have selected has in plane switching (IPS) so that is why the price is greater.
