<p>yeah. and the other ones are equal because -1(t-4 or wtv) is (4-t) and -1 * -1 is 1
so then if you negate both (things) or negative one (thing) and put negate the 3, then theyre equal. However, E negated the three without negating anything else, i think…</p>
<p>Length 4.
Width 3.
A triangle is drawn somewhere inside the rectangular prism and a 30 degree angle is made. You use that to find out the height is 5/SQRT(3).</p>
<p>Then you just multiply those 3 numbers</p>
<p>it gave the three-dimensional diagonal that had a 30 degree angle that formed a traingle with the base diagonal (length 5 since the length and width were 3 and 4) and the height. The height was found using SOH CAH TOA to be 5tan(30). V=l<em>w</em>h = 3<em>4</em>5tan(30) = 34.64.</p>
<p>for the rectangular prism one</p>
<p>it gave you the length 4 and width 5 i think
and then it said there was a 3D diagonal triangle thing with angle of 30, so you had to find the base of that triangle using pythagorean theorem and then use trig to find the height</p>
<p>then multiply it all together for volume</p>
<p>any questions that need clarification?</p>
<p>Anyone remember all the answer choices to the “which of the following functions does not equal the rest” question?</p>
<p>I’m almost positive that the intersecting spheres answer is point and circle since I remember rereading ti and seeing it say surfaces. Plus, it’s unlikely that’d the question would be solid spheres since that’d create irregular three-dimensional solids.</p>
<p>The answer was E. You could do some factoring manipulations on them all instead of foiling them out.</p>
<p>johnstucky: that’s correct. if you read earlier posts in this forum, you may have seen my debate with a half-wit over that problem.</p>
<p>Yes, #29 and #48</p>
<p>Nuggers, there’s no way anyone would be able to remember all of those answer choices unless s/he a) had photographic memory or b) entered them all of the asnwers into their calculator.</p>
<p>Don’t remember what E was, that’s why I’d like to do it again. I just plugged 1 in for t and got 4 positive values and 1 negative value so I assume I got it correct, but I don’t remember which letter I got so I’d like to try ig agian.</p>
<p>Tetratic:
For number 5 on the list, I answered only II. I was thinking that by “for all values of X” it meant all x values on the coordinate graph, even those that weren’t part of the graphs of the functions given. So I thought y=2^x didn’t meet that requirement. I just chose the linear function y=4x+something.</p>
<p>Also, do you remember if you got C for the last problem (#50)?</p>
<p>houstonrep,</p>
<p>I’m not sure which problems you’re referring to</p>
<p>@JacksonB15135 29 was the one with two t-tables where you looked at f(3), which is 2, then subsequently, g(2), which was 0.</p>
<p>Doesn’t hurt to ask johnstucky :P</p>
<p>@Nuggers Haha, true :)</p>
<p>@tetratic: #5 on the list on this thread, where it gave a list of functions and asked which of them are/is increasing for “all values of x”.</p>
<h1>48 on that list?</h1>
<p>The definition of an increasing function is:</p>
<p>f(x) is increasing IFF f(a) >f(b) for all a>b</p>
<p>Thus, the exponential and the line with positive slope were both correct</p>
<p>I’m not sure why anyone would know that definition if they hadn’t taken calculus…</p>
<p>what do you guys think a raw score of 35 will get me on this specific test?</p>
