I don't even know how to start. I spent 2 hours raging on the question... Help would be kindly appreciated.

I've tried to do Q5 and I got the part a (the equation) correct but when I plug in the numbers for Part b it doesn't work.

Here's a printscreen of my problem:

I've also discussed with my group members and we all couldn't get Q6, although it seems correct.

Thanks.

For Q5 b) read the question again, read your answer again and then think hard. There's a little modification to make.

For Q5 c) it might be that the thing wants units.

For Q6 all I got to say is that as soon as people get a hammer every problem they have looks like a nail. Read the question again carefully.

Okay thanks :)

Does anyone know how to do problem 11?

Can you be more specific? What about the problem do you get, what part do you not get?

You have to label what those numbers represent. On a side note, the last question f'(225) = 1.2, I'm pretty sure I know the meaning of this statement, but I am unable to express what I mean to WebWork without it getting angry at me. I interpret this statement as saying that for 225 gallons of Ice Cream, you need to spend $1.2 dollars per gallon.

I had the same problem with #11 too. Webwork doesn't seem to accept any statement that I input for the 4 blanks for Question #11.

i got it now. try inputting the actual word instead of units. ex: second(s) or minute(s).

Does anyone have an helpful tips towards solving for the second derivative below:

Find $y''$ for $y=2(x^{2}-6)^{3}$

Did you compute $y'$ already?

Try expanding what is in the brackets first, that should make it easier to find the first derivative. Hope this helps.

Hey guys, I've been giving a shot at question 3 but I have many doubts regarding the wording... in one of the situations, it states that Ed, Pascal Jason, the right fielder and the centre fielder are bachelors, the others are all married. however, Ed's sister is engaged to the second baseman. does this mean that I can consider the second baseman as married or as a bachelor?

Also, consider these two statements: Pascal and Charles each won $20 from the pitcher at a poker game, Ed and the outfielders play cards during their free time, I figured that this would imply that pascal and charles are both outfielders and that Ed is the pitcher. however, this is not the case. The pitcher can't be Ed since Ed is a bachelor and it states that the pitcher has a wife.

The reason I also brought up Pascal and Charles is because from the previous statement it would seem as if pascal and charles are part of the outfieldiers. We are also told that "All the battery and infield except Charles, Hassan and Adam are shorter than Sung" nulling the fact that charles is an outfielder...

It also states that Sung is in the process of getting divorced. once again can I consider him a bachelor or married? if I still consider him as married. what is the importance of that phrase in the context of the question? I am extremely confused as to how to take on this question. If someone could look at it id greatly appreciate it. Thx

Hey Marco,

I had similar issues with the problem and I still haven't completed but can't contribute a bit here.

Logically, being engaged is not being married. So, I treated the second baseman as a bachelor.

You are right; since Ed is a bachelor, he cannot be the pitcher.

I think this statement might be trying to confuse us a bit. Maybe there are, within the team, different subgroups of card-playing buddies and Ed and the outfielders form one subgroup and Pascal, Charles and the pitcher form the second etc....?

Once again, I treated Sung as a married man because technically he is still married. This information is somewhat relevant in the context of this problem because when you are considering solutions, Sung will be part of the married players. I guess they are just twisting the phrase to confuse us!

Hope this helps at least a little! :D

I gave this question a try but it's not making any more sense:

The graph of the function $f(x)=-4^{x}$ can be obtained from the graph of $g(x)=4^{x}$ by one of the following actions:

I don't know how the changes are reflected on the graph...I'd say the function has shifted vertically. What would the range for this be? I am lost...a hint please, someone? Thanks kindly.
