hmmm ok so i kind of flip the equation  over

#2 Re: Help Me ! » Confuzzling equations » 2010-12-24 05:28:31

D: uhhh still confused why didnt you add the two

#3 Re: Help Me ! » Confuzzling equations » 2010-12-23 15:26:47

ok but could you like explain from like all the way from the beginning cause i dont even see how 52.4 is equal to 686.44m²/s²

ok so im learning about the kinectimatic equations and i got stuck on ow exactly these steps work here is the steps

(0 m/s)2 = (26.2 m/s)2 + 2*(-9.8m/s2)*d

0 m2/s2 = 686.44 m2/s2 + (-19.6 m/s2)*d

(-19.6 m/s2)*d = 0 m2/s2 -686.44 m2/s2

(-19.6 m/s2)*d = -686.44 m2/s2

d = (-686.44 m2/s2)/ (-19.6 m/s2)

d = 35.0 m

and when do you know when your supposed to use sqrt or powered by 2?

Bundy why did you switch around the two big equations in the start?

#7 Re: Help Me ! » Ratio » 2010-12-19 13:39:58

I got the bottom left

#8 Re: Help Me ! » Pre-Algebra and Algebra II, and blah, and blah » 2010-12-19 13:35:12

It wasn't my decision to go on vacation but I will still be online smile
And I found a book about pre algebra but I'll still study here

#10 Re: Help Me ! » Pre-Algebra and Algebra II, and blah, and blah » 2010-12-19 06:22:29

ok woops didnt realize that xD ive only really been exploring the forums

#11 Re: Help Me ! » Pre-Algebra and Algebra II, and blah, and blah » 2010-12-19 05:56:52

ok bobby do you know any sites that teach you pre-algebra which is still a good website?

#12 Re: Help Me ! » Sin, Cos, and Tan » 2010-12-19 05:54:40

ok so first im gonna pick Sin because im trying to find the opposite and i know the hypotenuse. so the sin equation is Opp/Hyp = Sin(x) now replace the vars and i get Opp/12 = Sin(32) so now i find out what the sin of 32 equals and i get 0.52 now i do 12x0.52 and i get 6.35 now to double check i do 6.35/12 which equals 0.52 now i click sin-¹ so the length from A to B is 6.35 cm big_smile

#13 Re: Jokes » Chemistry » 2010-12-19 05:48:29

oook thats kind of wierd

#14 Re: Help Me ! » Ratio » 2010-12-19 05:45:43

when do you know when you have to subtract or add like on this problem? http://www.mathopolis.com/questions/a.php?id=345&ansno=1896&site=1

#15 Re: Help Me ! » Ratio » 2010-12-18 18:15:01

thanks and do you understand polynominals i dont get these pages sad http://coolmath.com/prealgebra/15-intro-to-polynomials/   plz help me

#17 Re: Jokes » Chemistry » 2010-12-18 16:38:46

I dont get the silver one?

Help me. Does anyone know what all these Pre-Algebra and Algebra I and Pre-Calc is im really confuzzled plz help and describe what they do. And are they like diffrent levels of math like Pre-Algebra is easier than Algebra II dunno

#20 Re: Help Me ! » Sin, Cos, and Tan » 2010-12-18 16:04:43

well i it dosent tell the right time for me on the forum but i live in washinton and right now its about 8 pm and whats MIF?

#22 Re: Help Me ! » Sin, Cos, and Tan » 2010-12-18 11:56:43

oh so i shouldnt have truncated?

#23 Re: Help Me ! » Sin, Cos, and Tan » 2010-12-18 11:47:29

ok go ahead and i dont know what truncated means?

#24 Re: Help Me ! » Sin, Cos, and Tan » 2010-12-18 11:28:12

kk but that is rounding 5 decimal places

#25 Re: Help Me ! » Sin, Cos, and Tan » 2010-12-18 11:24:42

ook so that would be the answer how is that 2 digits from the decimal?
