<p>It was 1/3sinx+2 and I think I got 3.87</p>

<p>Cauter…I think it was E (cant remember for sure though)…all you need to do is set ur calc in radians and plug in the choices in 3sinx to see when it gives you -2 to make the denom 0 and therefore make it undefined</p>

<p>also, what was theta for the sqrt37 / 3 / 4 triangle?</p>

<p>Thanks everyone :D</p>

<p>It asked for the sin of the angle in the rad37 so u do law of cosines to get 120 so sin is .866</p>

<p>i got 120 for the angle</p>

<p>am I the only one that thinks the test was hard? D:
it sounds pretty dumb considering i’ve gotten 800s on all 6 barron’s practice tests, but I ended up overconfident, managed my time horribly, and didn’t even answer three of the questions. Should I cancel my score? If you keep it, do you have to send it to a college that asks for all scores?</p>

<p>@mathisfun I don’t remember there being a double angle one… I do remember the sin^2 one which u got sin=1/1.61 so theta is 38.4 I believe</p>

<p>was the exponential regression one 24 weeks?</p>

<p>theta was 120 deg, so sin theta was (sq rt of 3)/2 = .866</p>

<p>Yea @clicksend 24 for regression</p>

<p>Aww, I forgot the law of cosines…I knew I had to use it though so i guessed .5…I had it down to a 50/50 and guessed wrong :(</p>

<p>@iiclicksend i remember getting 20something</p>

<p>what did everyone get for the 0.92 % growth for 293million people?</p>

<p>and 50% for box and whiskers? I thought it was a trick question because it was so easy x.x</p>

<p>was 24 C for the regression?</p>

<p>I may have put 27…was that a choice?</p>

<p>What is 4 wrong and 2 skipped?</p>

<p>@mathisfun111 i’m pretty sure that’s 800</p>

<p>btw nice forum name lol</p>

<p>I got 0.92% as well</p>

<p>Thanks iiClickSend :)</p>

<p>@Hiking7610 Caturday asked what did you get for the .92% question, not if you got .92% as an answer.</p>

<p>I’m fairly confident the regression one was 21 weeks.
After 5 weeks it was 850 right? So you’d get an equation like this</p>

<p>400e^(.15t)
and you were looking for 10000, so just set that equal to 10000 and solve for t.</p>

<p>798 for rectangular prism, 3.87, and 50% chance of drawing a sum >100?</p>
