<p>and please let's put the golf ball question to rest, it was 4.9</p>
<p>i was one step away from the answer to the 44th question when time was called. the one with the 117 degree angles and you had to use law of sines to find the answer.</p>
<p>wow i cant believe i missed that one. (x-8)(x-16) was what I was thinking, and WHY WOULD I SAY THE ROOT IS -8?!?! doh. ok you win.</p>
<p>oh there was one i wasn't sure about, it was like...the graph of that exponential function...like</p>
<p>8x^{2x-1}+7x^{2x}=f(x) or something similar to that, and the question was to find how many times it intersects x-axis...that was one right, because towards the left, the graph intersects once, and at the right, the graph approaches y=0 but never gets there</p>
<p>it said "one root is greater than twice the other" => 8 and 16 are not applicable. check out 0 (option C). then roots become 0 and 24 and 24 > 2X0 . rite?</p>
<p>i dont know...I graphed it and I thought I saw it intersect x-axis twice</p>
<p>but that was just the n00b eyeballing method</p>
<p>yupp 8x^{2x-1}+7x^{2x}=f(x) intersects once.</p>
<p>Does anyone remember the car one with angles and tangents? Was the difference 60?</p>
<p>yea it was 60</p>
<p>"what was the answer to the question: find the value of one of the roots of the quadratic that has two roots, one is two times the other."
The answer was A. 16</p>
<p>"ok here it is, i still had it saved on my calculator</p>
<p>h(x)=-5.25x^2+25.25x+1.5</p>
<p>when x=4.9, h(x)=0</p>
<p>there, that ends this golf ball problem confusion</p>
<p>the answer is 4.9, and that's final"</p>
<p>That's incorrect. The equation is wrong. The coefficient has to be -4.9 (thats given) and when I look at the table in my calculator, I get (0,1.5) (correct) (1,21.5) (no decimals in original table given on test) (2, 31) (3,30) and (4,18.5)</p>
<p>I swear I saw something like (3, 34) (4, 32), etc. Anyone else confirm this?</p>
<p>If my table values are correct, then your equation can't be right. Sorry if it seems like I'm being an arse. I only answered 41 questions, and I worked on like 3 that I didn't even put an answer down. So I'm a little worried. If I get every single one of my 41 right, then I won't cancel. But right now if I know I missed 3 or 4, I'm canceling. This is why I need to know the answer to questions I wasn't sure on, i.e this one.</p>
<p>8x^{2x-1}+7x^{2x}=f(x) only intersects once. It approaches 0 as x apporaches infinity but never gets there.</p>
<p>damn, must have plotted the wrong graph.</p>
<p>and btw firewolf, it had the values (2, 34) (3, 32) (4, 20) NOT (3,34) and (4,32)
(not sure if that makes any difference)</p>
<p>What about the one with the triangle and the coordinates? If the coordinates are three times larger how larger is the triangle? I guessed on this one and put 9 but I'm thinking its wrong. :( What's the answer?</p>
<p>No.3 with the inequality is -5<x<0 right? I think it was B. I can't believe I got stuck on such a stupid question.</p>
<p>what about the probability one with lake county in indiana? was it .001?</p>
<p>virtuoso i got 9 i think thats right</p>
<p>what about the probability one with lake county in indiana? was it .001?</p>
<p>^yay!</p>
<p>how do I get into chat?</p>
<p>9 is right...I thought it would be too easy and put 4.5 :(</p>
<p>Probablity for Lake County in India was 0.32</p>
<p>You just divide the population of Lake County, Indiana (top left box) by the population of all Lake Counties in the US (top right box).</p>
<p>Rest of the info about totals was extraneous and meant to trick you into trying to find total populations or something</p>
<p>how do I get into the chat room? Is it AIM chatroom?</p>
<p>So can someone invite me please?</p>
