<p>yes it was -3i. btw, what was the answer for the question that showed a figure and was about the height? the height 12 was shown on the figure ; the answer was the new height/// what was the answer/??</p>
<p>Nobody can figure out the hiking question on my Official September ACT Discussion thread…can any of you guys figure it out? we are stuck with 100 or 300</p>
<p>Yea Nitro I’m not really sure which one of us is right. All I remember thinking was
sq((i^2)^2)=sq(i^4)=sq(1)=1
looking it over I just don’t know. </p>
<p>I do know that #59 was 100. Everyone got a double pass leaving 100</p>
<p>u dont square the i…only its coefficient</p>
<p>the thing is cowking, the B term is separate from the * term in the formula i think</p>
<p>if you are talking about the ferris wheel one, look at the first page for an explination</p>
<p>hiking is defenatly 100</p>
<p>SAT2350 how did u get -3i as the answer?</p>
<p>and for the ferris wheel one (if thats what ure talking about)</p>
<p>it was 12+40-40cos(alpha) (pretty sure thats what everyone else got too)</p>
<p>nitro - it said what b value made it the largest though, so im geussing the entire thing was just B
ive never seen a question like that on an act math so, this ACT was much harder than usual (and the problems were so much longer -_- )</p>
<p>and if the B value is separate then -3i would make it the largest, but if it was (bi)^2 then it wouldnt be the largest.</p>
<p>the formula looked like it was only dealing with coefficents and not the imaginaries so thats why i thought it was -3</p>
<p>the a and b values are the coefficients…they dont include the “i” so u would not square the “i”</p>
<p>i^2 = -1, so sqrt (-1^2) = 1. -3 is the answer.</p>
<p>Cowking I understand why we are wrong now. b is just the coefficient in a+bi. It is b^2 not bi^2. Ok one wrong not bad.</p>
<p>what was the answer to the logic one?</p>
<p>beanonionlol they didnt inclue A in the answer though (although it could have been 0 + [answer]) </p>
<p>just remind me what the final sentence said, im pretty sure it said which b would give the largest outcome ahhhhhhhhhhhh</p>
<p>they made this one insanely confusing, since its debatable on which way u did it lol</p>
<p>maybe theyll take both (:D)</p>
<p>the answer to the logic one was the last answer choice if im not mistaken…the one that had 2 NOTs</p>
<p>yea thats what threw me for a loop on that problem cow, and yes i figured itw as 0 + [B coieffient]</p>
<p>i think 2 of them had 2 nots,</p>
<p>i put the one that said:</p>
<p>if it is NOT a cat then it is NOT blue</p>
<p>****. Has -1 ever been a 36 on the ACT math?</p>
<p>logic one is last answer</p>
<p>what about the one with A THOUSAND GEOMETRY LINES</p>
<p>lol it had 3 paralells, with a perpendicular in the middle crossing them and a diagonal</p>
<p>last question said one angle was double another</p>
<p>i put 120 for the answer, seem right? (i couldnt figure out the geometry i just said hey it looks a bit bigger than a 90degree angle :P)</p>
<p>My answers:</p>
<p>3i
12+40-40cos(alpha) (I believe this was D?)
120 for geometry angles
the matrix I just added the number individually up?
100 for hikers
40 for angle inscribed in a circle.
logic … if not a cat it must not be blue (E?)</p>
<p>the one with the double sized angle one was 120 i think, but yea what about the one with all the = signs with the tilde on the 10000 lines problem (congruent? lol i havnt taken geometry in forever)</p>
<p>i think i put the one with the 2 lines that were facing upward in a / shape around the center perpindicular line, i think the question was which ones do NOT somthing</p>
<p>Nitro: ya i remember that one, i think i got it right just dont remember what it was (too many letters lol)</p>
<p>i think everyone over thought the 2 angle problem. it was just 2x+x=180. 2x is the larger angle.</p>
