Dawn ,'Selfless'
[NAFDA] Spike-centric discussion. Lusty, lewd (only occasionally crude), risque (and frisque), bawdy (Oh, lawdy!), flirty ('cuz we're purty), raunchy talk inside. Caveat lector.
I'm confused, then. Then there are only two possibilities, right? That the base is is either 2 x 2 or 1 x 1?
eta xposty...
That's assuming the answer is in whole numbers. (Too lazy to go back to the question and see if that assumption is stated.)
Anyway, if I were writing the question, I'd make it so it'd be much harder to guess in this way. Or else include the "using differential calculus, show why this is so" part.
Who said that the sides had to be integers?
Yeah, I just realized that. Oooops.
So that makes x=y.
(x^2)z = 8
20x^2 + 40xz
160/z + 320/x
Aaaand, yeah, I forgot how to do calculus.
Brain hurty, go play with pretty words now. Sweep numbers into pile and leave for odd people to play with.
OK, P-C:
x^2 * z = 8
z = 8/x^2
C(x) = 20x^2 +40 xz = 20x^2 + 320/x
C'(x) = 40x - 320/x^2
To find the minimum, find where the derivative is 0.
0 = 40x - 320/x^2
320/x^2 = 40x
8 = x^3
2=x
Ooooh yeah. Now I remember that shit. Thanks!
Ooooh yeah. Now I remember that shit. Thanks!
t I think they're "speaking" gibberish and hoping the rest of us will think it makes sense. I've got a better chance of understanding Xhosa
Sits in the corner with connie. Cries in pain from the splodey math. Notices connie and is much happier.
Seriously, I had a linguistics professor who would write fill in the blanks, where multiple answers would make the statement correct, but he never gave credit unless you guessed the one he was looking for. You are completely not like that, Hil. I get that, even if the math makes my head explode.
Also, much of linguistics is a lot like math, with rules and equations and all. And yet, I loved linguistics. Actually, when I think about it, I loved math too until I got the hockey coach for geometry, at which point, as mentioned above, splodey head.
Hil, DH still had to show his work on actuarial exams, with only partial credit given if the work didn't show how you got the answer--so explaining HOW you got the answer is still de rigeur. Getting a right answer with a lucky guess doesn't help you build the skills that will help you solve the next problem that comes along.
I agree, though, that this will probably become an Issue (with this student).
Aimee? Joe? Are you sure you brought home the right baby from the hospital? [link]
Oh, goodness. That was hysterical!
SUCH cutie Buffista toddlers!

Sits with connie. Good corner it looks like!
Happy Birthday, Christopher!!!
Timelies, everyone!
I wake up and my bored (eta: this totally was a typo but I'm going to leave it because it's funny) is covered in MATH!
(Actually, I loved math all the way until I got to...some class whose name I don't remember but it had tons of matrices. I told this to Hil earlier this month - math was gret until I had to apply it to physics. Then it sucked.)
