<p>I thought that was the easiest MATH IIC test ever. The one I took in May was ridiculously HARD. I only skipped a few this time and hopefully didn't miss any. This time the curve will probably not have 43 = 800... probably 45 = 800?</p>

42

<p>that's what i thought! i agree with you aquamarinee. what did you put for the heartbeat one?</p>

43

<p>so what is the answer to the heartbeat question? anyone positive?
i kinda thought 60 made the most sense cause i looked at it from a bio perspective... a person who is at rest for a minute has a heartbeat of 60beats/min but idk</p>

44

<p>damn i was in such a rush i misread the combination one. Thats two wrong (i put four points, not two circles) and 6 blank...hopefully no more wrong</p>

45

<p>Wasn't it half of 120? I forget. Hahaha. Something like that.</p>

46

<p>i dont understand that hb one... could someone explain?</p>

47

<p>I always skip the probability problems... -6 points for skipping 6 so far. Hopefully zero wrong XD </p>

<p>What was the answer to the ax^2+bx+c one? It was asking which graph would have sqrt(b^2-4ac)>0? Was it D or A or something? I forgot...</p>

48

<p>how many do you think we can get wrong to get at least a 750?</p>

49

<p>aquamarinee-it was D</p>

<p>and it was <0</p>

50

<p>for the sqrt(b^2-4ac) one, it was the graph that didnt have visible x intercepts/ the one below the x axis</p>

51

<p>YAY I put D too. I think. Coool. That's what I thought.</p>

<p>You need to have 38+ raw for 750+.</p>

52

<p>wait...was it E then?</p>

53

<p>does anyone remember the qtion: cosx= - sqrt(1-(sint)^2).. was it it quad II and III?</p>

54

<p>AHHH...i cant remember the answer choices lol. it was the upside down parabola below the X axis, right?</p>

55

<p>yeah i messed that one up, you just think about -cos x = cos x</p>

56

<p>yea i think so.. lol i cant remember the choices either!</p>

57

<p>Yes, II and III. I used TI-89 which said Cos(theta)<0. Yay for TI-89's.</p>

58

<p>seriously, i keep panicking everytime i think about these questions!!!</p>

<p>for the hb one, i plugged it into my calculator and i got 145.</p>

59

<p>No, it was D. That was the last problem I looked up. (Your answer's right, yzheng)</p>

60

<p>What else was there that I was confused about... I can't remember now... hahaha... xD</p>
