Ask me anything!

[Aqualung]

Aqualung, I have a couple of questions for you......since you mentioned your father wasn't interested in the church, did he object to you joining or to the fact that your mother is investigating the church?

Yes. He objected to me talking with the missionaries, to my baptism, and he even objected to just coming to church one day with me. He is also not too happy about the fact that my mom is looking at it now, too.

And how did you pick Aqualung as your user name? By the way, I really like it.

Thanks. I was listening to the Jethro Tull song Aqualung when I was trying to find a user name (for a different forum) and since then I have just always used it when possible.

No no , there is air to blow up volley balls and blow up basketballs!:bonk:

Oh, well, yeah. I didn't even bother saying that because everybody knows that!

 

[standing_alone]

Um, you didn't answer my question! I'm curious to know. Here it is again:

A jet plane traveling at 600 mph overtakes a propeller-driven plane that had a two hour head start. The propeller-driven plane is traveling at 200 mph. How far from the starting point does the jet overtake the propeller-driven plane?

I just need to know the answer to this!

 

[Aqualung]

I'm working on it!

 

[Aqualung]

600 miles.

 

[standing_alone]

Hang on, I've got to look it up in the answer section in the back of the book...

 

[standing_alone]

:clap Hey, great job! You got it right! Wow, how did you figure that out? I have no comprehension of math, whatsoever. (I can't believe you actually took time to figure it out :biglaugh: )

 

[Aqualung]

Meh, it's magic.

 

[standing_alone]

Meh, it's magic.

Ah, wow. No, but seriously, how do you solve those kinds of math problems? I can't afford to fail math again this semester.

 

[Aqualung]

the distance between them can be written as 400 + 200t - 600t, where t is the time after the 2 hour head start. Solving for d=0 (i.e the time they meet), we can get the time they meet. At this time, they are the same distance from the starting point. Since the distance between them is written as absolute_value(distOfJet - distOfProp), plugging in this time to the prop distance (or the jet distance) gives us the distance from the starting point. So 600*1hr = 600 miles

Wow, you are smart. :clap But I did not understand that at all. I'm so stupid.

 

[standing_alone]

Oh, and thanks for answering all of my stupid questions so far. I'll try to keep 'em coming.

Ah-ha! Did you ever break any laws or partake in any other kind of deviant behavior?

 

[Aqualung]

Ah-ha! Did you ever break any laws or partake in any other kind of deviant behavior?

Um, no. I'm really good at behaving juuust well enough that I'm not breaking laws/rules. If I don't like you, and you're in a position of authority (because I usually don't worry about anybody else), I can make your life pretty miserable without actually doing anything wrong. I did this to teachers sometimes. Now, though, I'm not allowed to, because if teachers find "character flaws" they can get you expelled from the teacher ed program. But, yeah. That was more my style. I knew the laws really well, so I never quite broke them.

Here's a simple question for you, since you seem to know everything. (and it is a question about you)

Let's pretend you have a ladder (or maybe not "pretend," if you happen to actually have one)
Your ladder is 10 feet long and you lean it against a vertica wall. If the bottom of the ladder is sliding along the ground away from the wall at a rate of 1 foot per second, how fast is the top of the ladder sliding down the wall when the bottom of the ladder is 6 feet from the wall?

 

[Aqualung]

What's with all these math problems?! This one will take me a bit longer than the other one, that's for sure...

 

[Aqualung]

Will I have to show you the work, too, rubix guy (I'm not even going to try to figure out what your random letters and numbers name is)?

Of course! How will anyone be able to verify that there are no errors in your calculations?

Oh, and it is the "1337" version of "hexadecimal" (or base 16 for you math people)

 

[Aqualung]

Okay, here goes!

You start with the pythagorean theorum of the ladder, wall, and ground. The pythagorean theorem gives us that x^2 + y^2 = 100 (which is 10 squared.)

Differentiating each side with respect to 't' (using the chain rule) gives us 2x(dx/dt) + 2y(dy/dt) = 0

Solving for dy/dt we obtain -(x/y) (dx/dt)

We are interested in the point where x = 6, so the pythagorean theorem gives us y=8

Substituting all known values we get (dy/dt) = -(6/8) (1) = -3/4 feet per second

Well, I'm sort of going off A_E's thread about his beliefs, except you can ask me anything, not just about my beliefs (well, anything about me or my beliefs - you can't ask me unrelated things). The only thing I'm not going to answer is my name. If you ask something else that I don't feel comfortable answering, I'll tell you then, but I can't think of anything else. So, fire away!

Initially, I'd like to extend my appreciation and respect for for your interests in teaching. Knowledge is useless until it is shared. Teachers present knowledge as being both advantageous and acceptable. Eradication of ignorance is the surest path to peace, tolerance, and justice - and good teachers lend the best hope to those lofty goals.

As you alluded to your focus on mathematics, I'm curious as to what take or personal perspective you would lend regarding the validity/merits of "M-Theory".
