<p>I think the answer to the boat one was $3,600</p>
<p>there was a question like this:</p>
<p>so many people did A
so many people did B
so many people did both A and B
so many people did neither</p>
<p>and then it asked like how many people did neither?</p>
<p>that was the bike and treadmill one. I put 153 i think</p>
<p>ye it was the arc sin 10000/8*5280</p>
<p>Bike was:
Treadmill-Both + Bike-Both</p>
<p>Right?</p>
<p>i put 153 as well but can’t really justify. can anyone explain how they got $3600? and does anyone happen to remember if that was the first (smallest) choice?</p>
<p>thanks</p>
<p>See In my head I thought it was Arcsin(10000/8(5280)), but I don’t remember seeing that in the answers. There were 2 Arcsins, one without the conversion from miles to feet, and another I think was wrong. </p>
<p>Also on the last one, about the raining and the thing being canceled, Was it the last one? (E or K) ?</p>
<p>you do 117 - 53 = 64
89 - 53 = 36
64 do only treadmill
36 do only bike
53 do both</p>
<p>ALL = 153</p>
<p>i got K but I have no idea what it said lol</p>
<p>also emergency helicopter question was 26 miles.</p>
<p>I think I did (Treadmill + Bike) - both and got 153</p>
<p>i got 153 too now that I think about it. i did some math (no, really?) and I remember doing 175 - 22 and getting 153.</p>
<p>30000<em>.07</em>30(sold in july 2006)-30000<em>.06</em>33(sold in july 2005) = $3600</p>
<p>Did you guys get 1/2f(x-2)-4</p>
<p>^yes. the 1/2 in front horizontally stretches, the (x-2) moves the figure TO THE RIGHT 2 units, and the -4 makes the bottom of the function start at -4. </p>
<p>it’s actually amazing how *<strong><em>ty I thought I did until I came here. I think I got like 3-4 wrong at most. holy *</em></strong>.</p>
<p>The helicopter one, It was like 4 miles north, 2 miles east. Which gave you Squareroot of 20
Then it was 22 miles south and 6 miles west, which is Squareroot of 520.
Just add the two together and I got 27.3, but I just chose 26 because it was close.
Did anyone get 26 exactly?</p>
<p>I did the same too.</p>
<p>What was the 16% question? The center of the circle could’ve been any of those three options and the LCD was 4(x-2)(x+2)</p>
<p>for like a minute i kept getting over 26… and since I have OCD, i needed to make sure I got it exactly because I didn’t want to get it wrong. I eventually made a rectangle out of it, had to find the hypotenuse, turned out to be sqrt 576 or 26.</p>
<p>Yes you can just do distance formula from the point (2,4) to (-6,-22)</p>
<p>Sqrt of 676 not 576 is 26</p>
