<p>wait, what was the circle and plane question</p>
<p>soooooo…what is the final answer to the function question and the log 300000 question.
I put I and 18.2. Also, can you omit 4 and get ^these two wrong and get an 800?</p>
<p>18.2 wasn’t an answer choice. It was 19.</p>
<p>it was 19
function: im still not sure, ppl are saying I / II, III / I II / I II III
what was the circle plane question</p>
<p>i hope the curve is like a 43 is 800</p>
<p>lol…i swear i put 18.2 as an answer</p>
<p>I’m still curious if 3 and 3.125 were two different answer choices on the max/min question. Considering that they tend to round to the nearest integer on these tests I selected 3 and moved on to save time…</p>
<p>i still cant believe the probability thing is 0.997 instead of 0.883</p>
<p>3 and 3.125 were different answer choices D:</p>
<p>Pretty sure func q is II and III. And what was the answer to the question with (x^2-y^2) = 1
The choices were intervals</p>
<p>@Imperviouss </p>
<p>The question: something like “If x^2-y^2=1, and -1<(x-y)<0, what is true about (x+y)?”
What you had to do was:
- split up the difference of squares → (x+y)(x-y)=1
- plug in any negative fraction (whose value is less than -1) as (x+y)…
-------> I used -1/2, so I had (x+y)(-0.5)=1 - Looking at that, it was easy to observe that (x+y) = -2… </p>
<p>So, in order for the equation to be true, (x+y) < -1. (A)</p>
<p>@Killerskullz - wauw! Thats impressive. I have taken 10 practice test, and still runs out of time. How did you pratice? I am a foreign student, but have math on advanced level (supposedly the same as pre-cal)</p>
<p>I think I remember putting 18.2 for me as well. </p>
<p>Does anyone remember the question asking for the number of time the digits 1, 2, 3, and 4 can be arranged if 2 has to always be followed by 3? I got 6.</p>
<p>yay…biovball i hope we are right. </p>
<p>ok lets settle the function question now. The question asked when y is a function of x, and the site below states that if the same y’s are shared by different x’s, then it is NOT a function. Therefore III is false. II had, I believe, two different x’s and two of the same Y’s, 0. The case is the same as III, so therefore it is false. I believe I is the correct answer since all y’s had a unique x coordinate. </p>
<p>[What</a> is the difference between “is y a function of x” and “is x a function of y”? - Yahoo! Answers](<a href=“Yahoo | Mail, Weather, Search, Politics, News, Finance, Sports & Videos”>Yahoo | Mail, Weather, Search, Politics, News, Finance, Sports & Videos)</p>
<p>^yahoo answers… what a credible source.</p>
<p>two x’s can have the same y. </p>
<p>example: (x^2-4) 2 and -2 both get a y value of 0.</p>
<p>Aww man you’re right :(</p>
<p>Okay i’m confused now. What does it mean by y as a function of x?</p>
<p>Wait nevermind, got it.</p>
<p>The answer was II and III
end of story :)</p>
<p>Function q must be II and III</p>
<p>Oh wait now I remember the 18.2/19 question! You had to divide log 300000 by log 2 which goves you 18.2. Then the question says that the answer is the nearest integer GREATER than that. So 19.</p>
