September ACT Math Discussion

<p>I used a physics formula and Yinitial was 32 so the answer was height off the ground to start. I got 40 for the angle. I agree with the ferris wheel explanation too. I thought the math was really easy. It was my first time taking the ACT after taking the SAT twice. 770 math score (800 math 2) so for some context I’m good at math. </p>

<p>Also I got 45 for the cabin (notice the pattern of add 2 then add 3 then add 4 etc.) and the one with i^2 for complex I think.</p>

<p><NTP is twice <BAC (made up acronyms). it was on the question with the big angle diagram and 3 or 4 sub questions. i put 120 degrees…</p>

<p>what about the cabin house? what was the number of paths? =?!</p>

<p>nvm, did it right :)</p>

<p>what was the answer for the trapezoid question? and what was the answer for #59??</p>

<p>why i^2?</p>

<p>yet to take math 2 but i got an 800 on SAT I, math</p>

<p>this is my first ACT <em>fingers crossed</em></p>

<p>i^2 is wrong. the answer was -3i</p>

<p>yea i got 120 degrees, cabin house was 45, and plz be more specific then #59 lol, i dont remember that well</p>

<p>trapezoid was 13 (i think?)</p>

<p>trapezoid 13 if im not mistAken…wat was #59?</p>

<p>7 10 13 for trapezoid</p>

<h1>59?!? what Q was that</h1>

<p>yea, it increases by the same amout, 10-7 = 3 so you add 3 on to the middle meaning 10+3 which = 13</p>

<p>I wasn’t 100% sure on the i^2 but I thought that everyone that was not squared was negative and i^2 became i^4 which is positive. Please explain your side. Thanks!</p>

<p>sqrt 0^2 + (-3i)^2
= sqrt 9* i^2
= sqrt -9
= ???</p>

<h1>59 was a long question…100 300 500 600 900 were the answer choices i think??</h1>

<p>it was absolute value of the imaginary numbers so regardless negative doesnt matter, and if you plugged into the formula then -3i was the greatest</p>

<p>nvm i see your point, but i think the * was supposed to be separate from the B term, so you just use the number B with out the *</p>

<p>oh 59 was the hiking one? ahh im sooo dumb i made a silly mistake on that one…im pretty sure the correct answer is 100 though…1000-200=800 and then u would do 800-700=100</p>

<p>im almost 100% sure that it was -3i</p>

<p>no i dont think it was the hiking one, i thought that was like 40 somthing, correct me if you can confirm its 59 though plz</p>

<p>sqrt (a^2 + b^2)</p>

<p>it wasnt -3i cause (-3i)^2 = 9 * i^2 which is -9</p>

<p>i put i^2 which becomes i^4 which becomes 1 (only positive one i could find)</p>

<p>tell me if im wrong plz</p>
