<p>you switch the x and the y’s: x=ay^2</p>
<p>im pretty sure it was height since the velocity is constant so itd be a straight line</p>
<p>9 degrees??? Anyone else???</p>
<p>I also got 9 degrees</p>
<p>what was 9 degrees for?</p>
<p>Yup. I got 9 degrees for one of them, too.</p>
<p>For rotating it 90 degrees… switching the x and y’s doesn’t make sense to me. Wouldn’t that just be the inverse if you swap those two variables?</p>
<p>What about the flashing thing? One was 4 and the other was 14. Did you guys get 56?</p>
<p>It was the question on what Olympic sport students preferred. It asked what is the angle formed by the person who enjoyed “this sport” (there was only 1 person). there were 40 surveyed, so it had to be 9 degrees.</p>
<p>9 degrees? i thought it was 10 degrees?</p>
<p>Yeah I’m remembering a 9 degrees, can’t remember the question though…</p>
<p>it was 28 to the flashing question</p>
<p>I got 28. It was asking just for the time in between the flash. Not the total time it took for the light to flash twice.</p>
<p>@Nspire</p>
<p>If you rotate a standard parabola 90 degrees clockwise, you are essentially finding it’s inverse.</p>
<p>it asked for the time elapsed between first time (28) and the second time (56). the difference was 28</p>
<p>for the flash i got 56 too</p>
<p>I left the equation as is and plugged in values for “y.” From there, I got an “x” value. I got my parabola pointing to the right.</p>
<p>dam it i was thinking about it but then i read the intial time elasped. that led me to 56.</p>
<p>oh crap, what were the other choices to that 9 degrees problem? i mightve gotten it wrong…</p>
<p>I’m pretty sure the fence one was 240 not 252 because you get 252 as the total but have to subtract 12 of the posts used to get 240. He sides were 30 and 48 I remember and the stakes were 12 in between each post. Post was every 6 ft. Anyone want to confirm?</p>
<p>I got 252.</p>
