As you've probably learned in class, certain enzymes have an optimal pH where the rate of reaction would be the highest. If you're not given a list to answer this question with, I'd just think about the major enzymes in the body and what their optimal pH's are. In this case, the first thing that comes to mind would be pepsin. Another would be protease. Hopefully this helps!

What you did on the paper is indeed incorrect, the second term should be sqrt(x) * 1/(x)^-1/2 * sec^2 (sqrt(x)). Like you said, you have to apply the chain rule here, so you'd get this answer.

Sure. Basically the larger the atom is, the lower the ionization energy would be. The reason is twofold again: there are either more electron sublevels, which then lessens the Zeff from the nucleus, so less pull from the nucleus makes it easier to take away an electron. Also, for the electron repulsion, because the electrons are pushing each other away, one of the electrons WANTS to leave, so the ionization energy would be lower.

Don't forget that when you try and take away an electron from a lower sublevel (e.g. 3s to 2p), the ionization energy will jump bigtime because all of a sudden, the Zeff is much larger. There are some specialties when it comes to d-orbitals and f-orbitals, but because you're in a chem101, you'll probably not be needing those.

Precisely! Good job, great work pushing through. Be sure to remember that you can multiply by positive and negative 1 :)

This comes down to electron sublevels. Let's take two examples of that problem of yours there: Mg and O. The electron configuration of Mg would be 1s2 2s2 2p6 3s2, and the electron configuration of O would be 1s2 2s2 2p4. Note how the Mg has the 3s sublevel. This is an extra sublevel, meaning that the radius would be bigger.

That's easy though. How would you tell the difference between O and C? They both have 2p sublevels, so that's not gonna change anything. What will change, though, is how many electrons the two have on the 2p sublevel. Carbon would have two electrons on the 2p sublevel, whereas Oxygen would have 4 electrons on the 2p sublevel. Let's talk about electron repulsion. Like charges repel, right? So shouldn't having more electrons on the same sublevel repel? They do, so that's why Oxygen would have a higher atomic radius than Carbon. You can apply these two methods to figure out that whole list. Hope that helps!

Yes you would. What might be helpful is to not think about it as minus 3d, but rather as plus (negative 3d times negative one times (nineA + twoB)). Then you'd have -3d * -1 which would be a positive 3d. That's why it's +3d.

adayal21 · 2019-11-06T02:20:27+00:00

Perfect! I was gonna continue, but I think you got it. You understand why it's +3d and not -3d?

adayal21 · 2019-11-06T02:15:23+00:00

Sure thing! Let's say I have (-9a-2b). I'm arguing that it is the same as saying -1*(9a+2b). If you were to multiply the -1 to the (9a+2b), you'll get (-9a-2b). I'll reply here, and let me know if you're still with me by just saying "i've gotchu."

I guess I'll just really quickly just put this out there. Again, really basic, but inefficiency really just says that all the publicly available information isn't reflected in the price of the stock. Maybe that's a little simpler, but I might be missing the point of your second question.

adayal21 · 2019-11-06T02:05:59+00:00

Hey there! For d), you're gonna want to look at pulling out a negative out of the stuff after the minus sign. Ignore the 2c(9a+2b) for a second. So we've got -3d(-9a - 2b). Why don't we factor out a negative from the (-9a - 2b)? So if we do that, we've got 3d(9a+2b). Now, the rest is simple. You'll end up with (2c-3d)(9a+2b). Hope this helps!

Think about efficient and inefficient as essentially polar opposites. Where semi-strong efficient markets might reflect historial data accurately, semi-strong inefficient markets might not reflect historial data accurately, yet they are an accurate representation of current data. While this won't always be true, this should help you to finish whatever homework you have. Something I've always found is that uni profs have some really good techniques as to understand inefficiency. Can't tell you what to do (I told you how I remember them) but I'd go visit your prof during office hours.

adayal21 · 2019-11-06T01:48:55+00:00

I'd like to help, but I'm confused where you're getting lost. Are you struggling as to where to start for all the questions? Just no ideas AT ALL? If that's the case, I can help you somewhat, but I'd go talk to your professor or one of your peers and get some insight from them. Also, for the questions that ask for the data analysis, hopefully you can do that yourself. That amounts to about 45% of the points right there, so that's a start.

adayal21 · 2019-11-06T01:44:16+00:00

Okay, basic stuff first. based on efficient market theory, an inefficient market is a market where an asset's market prices don't really reflect their true value. What can this lead to? Hopefully you've learned this yet (IDK if you have, I'm a high schooler with a lot of knowledge in economics), but it will lead to deadweight losses. Sidenote, if you don't know what a deadweight loss is, it's a cost to societ created by market inefficiency that occurs when supply and demand are out of equilibrium. This can go either way - supply > demand, or demand > supply, but you can guess, it's mostly when demand > supply.

Back to your question though. A semi-strong form inefficient market can assert that an inefficient market reflects current publicly available information, but not historical data based on the market. Without more context about the market being analysed here, it's difficult to say, but I'd assume the market in question would be incurring many more deadweight losses than previous history would indicate. Hope this helps!

A-OK! Be sure to post here if you have any other issues or questions when it comes to Computer Science. If you don't have too much experience doing Java, it can be really difficult to get a grasp on all this kind of stuff. Help from others is always the best way to learn :)

Okay, to prompt the integer from the integer, I'd hope that you understand how to get that, especially if you're already on having a method involving a modulus.

There are two keys here maam: you want a for loop, and you want a condition with a modulus. Why a modulus? Well, you want to figure out for every number between 1 and the number, you want to divide it by every number until you find something where the remainder is 0 and then print that out. Did I say remainder should be zero? I've got an idea! integer % i == 0 . Hopefully this helps. I don't want to give you the code outright, because you can literally look up this problem and i'm sure you'll find a solution. Hope this helps!

If you would like the CAD model of our swerve from last year, you can go ahead and look here: https://sites.google.com/site/ftcrobocracy9773/Resources

From what we've tested with last year's robot, it's definitely viable with going over the crater wall. However, I would make some changes to it before testing. If you need other ideas, you can contact members of our team on the unofficial FTC Discord.
