I fucking love that man. He'll never win, but I still fucking love him.

Anybody catch Huntsman's gaffe about working with the "3 border states" to solve immigration problems. Apparently Canada doesn't exist and nobody ever comes over by boat. What the hell is he even doing in this race?

Also, I wanted to punch Santorum for two reasons. One, it might help straighten out his face. Two, he, like Rudy Giuliani before, has no fucking clue what Paul means when Paul points out, rightly, that the 9/11 attacks have an awful lot to do with our foreign policy.

What's new and what's good.

Eureka is more nerdly than anything, and sometimes they (the producers) don't do their homework.

Warehouse 13 is okay.

Fringe is hideous. Despite what people think, no it hasn't gotten better by going even more fucked up than before.

Game of Thrones if you prefer the more medieval type setting.

Terra Nova and Falling Skies I haven't seen yet.

Walking Dead first season was good.

Alphas is okay.

There's more that I'm missing I'm sure.

>>3725630

Ah Christ... I read it as a function composition.

Sorry mate. I'm getting all kinds of basic shit wrong tonight...

>>3725603

g(x) gets substituted for what f(x) is. Since f(x) is sqrt(x), {f[g(x)]} is sqrt(4x - 3).

Unless I'm backwards. Been a while since I've done those.

>>3725572
>>3725552

Oh wait, I see it now. You just used the quadratic formula skipping a few steps. Gotcha.

>>3725552

This is interesting:

"x=11+/-sqrt(121-120)/2"

I've never been shown this way to figure out a polynomial factor. I just went

(x - 5)(x - 6) with -5 and -6 being factors of the 30 and -5 and -6 adding to -11.

>>3725552
>>3725558

Shit, meant 5 or 6. Got it before me.

>>3725537

Okay, next time write the equation more clearly.

Now that I know:

x is -5.

>>3725522

No solution.

If 11x-30-x is all contained in the square root bracket, then x being 3 would solve the equation.

They often are intentionally in order to throw you off. The only relevance is the line segment points and the lengths given.

>>3724957

Having read the /a/ thread, this is apparently beyond my educational level. I wasn't even aware the lines in each side represented equal length. Then we get to the idea of the non-Euclidean geometry and I'm just completely gone.

So apparently the answer is either that there isn't one or the answer is 19. The original question is intentionally vague in order to troll.

>>3724924

In which case, nevermind, I'm a retard, it'd still be ~26.87

>>3724884

Oh, did I read that wrong. Were you looking for the midpoint of each line segment?

Who the hell can't figure out a simple Pythagorean problem?

a^2 + b^2 = c^2

19^2 + 19^2 = c^2

361 + 361 = c^2

722 = c^2

sqrt(722) = c

c = ~26.87

Start simpler. If you're getting 100km per every 2L of fuel used, that/s a 2/100 ratio. Reduce that to 1L/50km and go from there.

If you get 50km per liter of fuel, just divide the cost per liter by the distance gained per liter. Or 1.70 / 50 = 0.034 per km.

>>3724849's formula is accurate, if literal.

The singular most important way to improve your math skills at higher levels is to MAKE FUCKING SURE YOU UNDERSTAND EVERYTHING BEFORE.

I cannot stress this enough. If there was something you didn't get back in elementary math, algebra, precalculus, calculus, or higher math, make sure you figure that crap out before trying anything more advanced. You never know when it'll come back to haunt you.

>>3724803

Don't be a jerk. Factorials rarely get taught before the high algebra / calculus levels.

>>3724773

I would argue that people did exactly that and came up with conspiracy theories. They then only approached the 9/11 attack from that point of view, finding anything that supported their newfound theories instead of looking at the attacks from a neutral stance.

In some cases, thinking about the whys might aid in the hows, but I don't think it really helped here. If anything, it made things worse.

>>3724748 By the way, we had some fat girls in our engineering classes. When others pointed it out, we'd say that they were just designed by God with a safety factor of 2.

NNNNNNNNNNNNEEEEEEEEEERRRRDDDD!

>>3724731

>>3724726

"abunai" - "look out", "be careful", etc.

>>3724663

What I meant is that I can't believe you're that naive that you can't believe people still don't believe the official story. People are still denying various things even though the evidence is overwhelming that they're wrong as fuck.

Face it, people are fucking stupid. Become cynical towards humanity, it is the only way.

>>3724481

Correct answer.

Remember, a perpendicular line will have a slope that, when multiplied to the original slope, will equal -1. Thus, a slope of 3/4 will have a perpendicular line with a slope of -4/3. Put the original given points into the slope intercept format (given in >>3724347) and solve for y.
