<p>I think I did well on the multiple choice (probably only minus 3 at most), but I totally bombed the FR - I missed about 5 parts.</p>
<p>Is this a comfortable 5? D:</p>
<p>I’d say a comfortable 4…stretch for 5.</p>
<p>5 parts or 5 problems? 5 parts should be ok</p>
<p>definitely 5 =]
but BC this year is weird…so different from past</p>
<p>5 parts, not 5 problems. Haha. Like I missed part D of number 3, etc.</p>
<p>Oh then possibly a 5, egg!</p>
<p>this is number 2…</p>
<p>2) time 0<t<2
R(t)=1380t^2-675t^3
W’(t)= (2-t)(R(t)= (2-t)(1380 t^2-675t^3)</p>
<p>a)total ppl entered from 0 to 2
b) max of R(t)
c) total wait time from 1 to 2
d) total of total wait time from 0 to 2</p>
<p>a) intergral(1380t^2-675t^3,t,0,2) =980 ppl
b) R’(t)= 0=2760t-2025t^2
t=1.363</p>
<p>Check R (1.363) = 854.527
R (2) =129
R(0) =0
t=1.363 is when R(t) max
c)w(t)= intergral((2-t)(1380t^2-675t^3),t,1,2)= 387.5
d) im not sure what d really asking …i dont remember but if it just total wait time just plug 0 and 2 to that in part c</p>
<p>i think it ask for average total wait time
so if it asks that
put 1/(2-0) *intergral(w(t),0,2) and find the answer…must find w(t) first i guess…too lazy to do it</p>
<p>i got the avg waiting time is like 0.3blablahblah…
im wondering that if thats true in life lol</p>
<p>d) asked for the average wait time PER person so you would do TOTAL wait time/TOTAL number of people : 387.5/980</p>
<p>are we allowed to discuss this extensively?</p>
<p>When people say, “the curve is going to be 66!”, do they mean 66% or 66/108? o.o</p>
<p>Hopefully 66/108, and not 66%. Haha.</p>
<p>i think for part c is like this:
w’(t)=blahblahblahblahblahblahblah
intergral(w’(t),t,1,2)=w(2)-w(1)
here we use fundemental theory of calculus lol</p>
<p>and for part d, the theory is the same. just divided by the total number of people</p>
<p>I’m so happy to hear dx is not counted.</p>
<p>^^ 66/108 is what we mean.</p>
<p>^^ YAY! That means I have hope!! ^^</p>
<p>oh man i made so many dumb mistakes on number 2</p>
<p>oh noooooooooo…
how many credits would i lose for this…=[</p>
<p>^ yes. and d) asked for the average wait time per person so you would divide the total number of hours by the total number of ppl. </p>
<p>OKAY IM NOT DISCUSSING ANYMORE I DONT WANT MY SCORE TO GET REVOKED!!!</p>
<p>@powerbomb: well dont tell ur name and school and ur ap number…there wont be like FBI track u down bcause u discuss AP test questions…they’ll come into our classroom in next 48 hours…and im pretty sure that hawaii have finished taking it lol</p>
<p>my whole class discuss with teacher rite after the test…just dont be like so obvious</p>
<p>@kaiyan the limit is from 1 to 2 not 0 to 1 FYI</p>
<p>cant ETS track u with like ur IP number or something, lol.</p>
