October 2010 - Math II

<p>I don’t exactly understand Ssur’s explanation, but just based on -c+2 and lcl+2 is the same thing, I think the answer is c+2. And yes, it was looking for the max.</p>

<p>HEY HOLD IT RIGHT THERE MANAV77 !!! the question didn’t ask us "what should u do to get the max. value of y=c + |sinx| ? ", did it ?
as far as i can recall, it asked us : “what IS the PRESENT max. value of y=c + |sinx| if c is a negative constant ?” …</p>

<p>And manav77, to answer ur question , yes , it was |x|(1 + m^2)^0.5 …</p>

<p>omgomgomg i think i did well reading these posts
i omitted 4, 36, 37, 44, 49.
I am sure many screwed up on 35 heheheheeeh</p>

<p>my answer said answer was B but then i had to make that to inches, which the answer then magically becomes C.</p>

<p>^tricky classic.
comments plz.</p>

<p>Ssur92 if i can recollect correctly it was…what is the maximum value of the function…and u can only get a maximum value if c is positive…however i may be wrong since mod(c) would also give the same answer…i’m still unsure of that question</p>

<p>I had no idea how to get the ladder one (I think that’s 35?)…=( 4 omits, 2 wrong, barring any stupid mistakes, I have an 800</p>

<p>The compounded annually one…so was it 23 or 24…</p>

<p>4 omits 3 wrong…barring any stupid mistakes. What would that most likely end up as? 760?</p>

<p>it was 24. cuz the real answer is 23.7598q2ag928 or soemthing, but then answer isn’t 23 cuz it won’t be enough. the next one will be 24. yyeeeee</p>

<p>I’d say 790 Tuba, at least 780</p>

<p>I put 24 on the compounded annually one. It asked for the minimum number of days but you cant round down so i went with 24.</p>

<p>whoa…manav77, look… what’s the max. value of -|sinx| ? its nothing but 0 !!! </p>

<p>would u CHANGE the question and say that “in order to get the max. value u’ve gotta make it positive” ? think back to ur classes on functions, my friend…</p>

<p>so is the consensus lcl + 2 or c+2 ?</p>

<p>Does anyone remember the geometry question. I just skipped it since it would’ve wasted my time.It was a plane inside a cube or something.</p>

<p>lol…45fly…the D-Day is Oct 28th… i’m with c+2 obviously…</p>

<p>minus?
the maximum value of mod(sinx) is 1…and i still stand by my answer 100%…we’ll just have to wait and see further</p>

<p>i got 89 for the plane inside the cube one.</p>

<p>kingsknight, it was simply 4 * root(20sq + 10sq), i.e. , it was 4 * root(500) = 89.44 ~ 89</p>

<p>alright then, manav77… until the 28th of Oct, then… for now, let’s move on to some other questions… :-D</p>

<p>who wants to participate in making a list and see how many we got wrong?</p>
