Eh, But I still have an 11 as a freshman and a 49 on the SAT math. Do you think that will make it?
@lequalSmart I’m pretty sure that’s what it said. Might have read it wrong. Solved it using calculus which I took freshman year.
There are people who have gotten in with lower. Just curious, what demographic are you?
@Frigidcold I got those same answers, in addition to -6 being an answer for the perpendicular problem to find a, 10a/r for like the a/6 problem, -2<x<3, and 4√2 for that triangle problem
I think I got 10a/r which I think was d.
@zenith99 Got all of those answers too, high five
Talk to you guys tomorrow, I have a science fair tomorrow.
@Frigidcold high-fives back yessss! I hope this brings up my abysmal science score though lol
Ok two things. 1. For the problem with the volume = Surface area wasn’t edge = 6? Also how was 16/3 the value of x that leads to maximum value of 8x - 3x^2? when plugging that in I get a negative number.
No… Its asking for the one that is yielded by the expression. Not the largest x. Sadly I read minimum.
no but there were five possible answers (0, 8/3, maybe 3, 4, and 16/3). I plugged in all those and got 0 from the expression when plugging in 0 and 8/3 and a negative number when plugging in the other numbers?
sigh with that Im down to 50/50 easy math, somewhere in the 60s prob for science, 12/15 hard math with penalties on the way. And I’m a sophmore…things aren’t looking good
- The volume was in feet cubed and the surface area was in square inches, different unit.
s^3=6(12s)^2
- I only know how to solve it using calculus, so idk if you know the concept, it's called relative extrema. derive 8x-6x^2 8-12x solve for x to get 4/3 plug back into original expression to get 16/3
@Frigidcold Well im screwed
Yeah, I got 6 x 1728 as the feet for that problem. I also used the derivative to test the extrema through closed interval method.
Calculus sucks -_- (I’m a sophmore and I did not take calc).
Did u guys get 6 for the equal volumes equal surface area problem?
@penguinpal I believe the answer was 864, which is 6 x 12^2. 6 x 1728 would be 6 x12^3.
@CanisMajor There are people who have gotten in with lower than what you have, which I imagine is 10 or 11 on challenge math. Try to keep optimistic. I wish I could say the same to myself.
and .08 for the problem of selecting n as a perfect square out of 100?
- Equal volume and surface area answer was 864, the volume was in feet, the surface area was in inches.
- The probability was 0.08.
Feel free to look at earlier pages in the thread, all the answers are there
@Frigidcold yeah I realize that now…damn
I changed my answer on that one I think, since I last minute checked over some of the middle problems.
Now I am depressed.
