All four solutions: x=2, x=3, x=((1+sqrt(17))/2), x=((1sqrt(17))/2). You have to solve for 3x5=((x1)^2) and 3x5=  ((x1)^2) because of the absolute value sign on the 3x5. Plugging in the so...

I would say differential calculus.

I imagine you would have to use the Lambert W function, but I'm not familiar with it.

If you know the mass of water lost, you can calculate using stoichiometry the moles of water. Oxygen has a molar mass of 16.00 grams per mole (g/mol) and hydrogen has a molar mass of 1.01 g/mol. In...

Nitrogen has 5 valence electrons, so NH3 will have 8 valence electrons total.

I'm not the best a probability, and learned this method relatively recently, so forgive me if I get this wrong. Since we want 3 men from a group of 4 men, it would be (4!)/((43)!) = (4*3*2*1)/(1!)...

I recommend reading College Algebra by Stitz and Zeager. Their book is very useful and covers many of the weak spots Khan Academy has in math. Although Khan Academy is great, this book provide...

In my opinion, Khan Academy's APUSH course is lacking in content and core ideas, and definitely won't prepare you for the AP test, which was two days ago. AP prep books are usually a great resource...

I don't see what it has to do with vectors, but it shouldn't matter what order they are in.

I'm not sure how these resources compare to Khan Academy. I haven't looked at them myself, but they are still alternatives, so these could potentially be more useful: http://majorprep.com/blog/2018...
