Ok, I remember a little bit I should subtract z from both sides so I get u-z=vw+z-z which simplifies to u-z=vw but I can't remember from there.

I've got a different answer from the Actuary exam guide. You need to make a Venn Diagram and make x,y, and z into the middle portions of the diagram between AB, AC, and BC. From the question you know that x+y=1/4, x+z=1/3 and y+z=5/12. Adding these equati...

Weight is a force, and as described by Newton's Second Law, F=ma, where m=mass and a=acceleration. At sea level on Earth, the acceleration is 9.81m/s down, which is the pull of gravity. By taking the object up to the top of a high mountain, it will be les...

The demand function for a product is modeled by : p=10,000(1-(3/3+e^-0.001x) Find the price of the product if the quantity demanded is (a) x=1000 units and (b) x=1500 units. What is the limit of the price as x increases without bound?

Thank you Bob, but even after reading the article, I still don't understand how to obtain the parallel force acting on the block (question b). Can you expand perhaps?

F=qvB(sinθ) but sinθ=1 so we can ignore it. We have B =1.5T q=1.6x10^-19 We just need v from our Ke. Ke=1/2mv^2 v^2=2Ke/m Punch in 8.0x10^13J and look up the mass of a proton (1.672x10^27) and solve for v, which turns out to be 3.09x10^7. F=(1.6x10^-19)(3...

Well definately the more levels you have, the bigger the radius will be. However, also, the more electrons you have in that level, the smaller the radius will become. This is because the force of attraction will become greater between the electrons and th...

A hydrogen Atom makes a transition between two energy states and emits a photon with a wavelength of 434.2nm. What is the frequency? Does anyone know how to do this?

The sides should be proportional if they are similar, thus, since AB corresponds with wx, and Ab is 24 while wx is 16, 24/16=1.5 . So ABCD is 1.5 times bigger than wxyz. the other side is 30, CD, is 1.5x bigger than yz, so find that and get the area by mu...

okay, good, I think i did it right then (it was actually a question on my exam that I just completed, it was the only question I was unsure about)

Yeah probably, I also don't remember if it was 20435 or 20425 exactly, but it was approximately that.

Thanks Dr. B, I know to use that equation but the math is the part that I'm stuck on.

14 years ago

Yeah that's the same setup I have but I'm not sure once I divide 30800/8.314 if I take that number and multiply by the other side of the equation or if I'm supposed to FOIL it out with the temps in parenthesis? Thanks!

In q1, did you mean to say (110-100)? I did it assuming that and after I added all the q values I got 13,759.78 KJ as my answer. Is that correct?

I always thought it was funny how when your younger, they prohibit the use of calculators, only to make it so when you get into Algebra 2 and higher, you HAVE to have a calculator. Aha, just think that's amusing.

Ok, I set up the ICE table and found that Ksp of Ni(OH)2 is 5.48x10E-16. 5.48x10E-16=4S3 S=5.16x10E-6 Molar Now when you said convert this to grams I'm confused because the problem gives to the amount of grams used. I appreciate the help.
