<p>Lol, damn everyone with a TI-89, srsly. haha.</p>
<p>And sorry inveniamviam I meant to put pi in the formula but forgot..but on the test I got it right.</p>
<p>What did people get for the polynomail function with 3 pts?</p>
<p>I don't mean to be annoying but seriously..what were the answers to the vector question and compound interest question?</p>
<p>the ones i rememberfor the 4to the m and 2^n between -4 to 4 was 3 values right.. and please tell me tht was number 27 cause i wasnt sure bubled last minue</p>
<p>2/9 prob for number 49</p>
<p>m/(t^m) for the decay one </p>
<p>other decay one m was equal to 2?</p>
<p>ok one of the quesrions was like which values make it zero and it had like 1 2 3 6 but the value was -1 and 1 but the number of values was 2 so i put 1 as the answer i hope it was the number value not the number of solustions</p>
<p>parabola is (x-3)^2+2</p>
<p>hey for the standard deviation did u get 0.1</p>
<p>3587 or something i believe...</p>
<p>st dev was .1 ya</p>
<p>4to the m and 2^n for this one i got 5</p>
<p>Wow....
I had my calculator in radians mode, so when I did the vectors law of cosines problem, none of the answer choices followed my answer when I square rooted it. I just realized that when I got home. Instead, I just used pythagorean theorem when I didn't see my answer on there.</p>
<p>lol, what was up with the one where some of the answer choices were like A) 2M(sub zero)t
B) 2(M (sub zero))t
as if... that changes anything? I didn't get much sleep so maybbbbe it does.. idk</p>
<p>for vectors its 8^2+6^2-2<em>8</em>6*cos(130) and sqrt that so answer should be 12.7... i got that wrong :\ (i got 6.2) w/e....just one</p>
<p><em>edit</em>: ***? now im confused. is it 50 or 130? nvm it is 130... doh!</p>
<p>4to the m and 2^n did u get 5? possible values cuz 0 is an integer also</p>
<p>wasnt the 4^m and 2^n one 5 values (two of the points can be negative right?)</p>
<p>Yes standard deviation is 1 so is 3587.</p>
<p>Also, yes, the 4^m one is Five values because they can be negative.</p>
<p>Was the M0 thing E: /t^2 or something</p>
<p>t^2? wasnt it 2^t?</p>
<p>fo the symolsquestion with the triandle did u get C??</p>
<p>Yeah 5 values, .1 standard deviation</p>
<p>

yeah I had 6.2 at first as well, because I used 50 the first time, but you can see that 6.2 can't be the answer because it's smaller than 8 and the sum of the vectors is obviously longer than either of the vectors themselves. And yeah, use 130</p>
<p>Oh, yea 2^t. The symbols question + was mult, tri was divide...not sure if it was C though.</p>
<p>why cant you just find the components of the vectors, add them together, and use the Pythagorean theorem?</p>
