<p>Thanks ricorodriguez.</p>
<p>i dont remember the combination one too well. do you remember the question?</p>
<p>It was something with subsets and 5 total people, or something.</p>
<p>two more questions:</p>
<p>F(x)= K log 5 (X)....5 was the base, and K is a constant</p>
<p>whats does F(5) - F (25) =?</p>
<p>**Answer: -K</p>
<h2>**</h2>
<p>How many different subsets of either 3 or 4 can be formed from a group of 5?
Answer: 5C3 + 5C4 = **15**</p>
<p>yeah i got 15 and -k as well.</p>
<p>Why wouldn't you multiply them?</p>
<p>math, do you remember the point a and point b one?</p>
<p>Three planes can intersect at a point...</p>
<p>either ... or = add.</p>
<p>procrastination, how could they intersect at a point....try to get 3 pieces of paper to intersect at a point. the only way of doing it it by touching all the verticies (i.e. the corners) the problem is that there are no corners to planes as each extends for ever in 2 dimensions</p>
<p>two form an X, the third slices at the point</p>
<p>does anyone remember the distance between point a and b one?</p>
<p>oh i remember the point a and point b one with the triangles and one side is 8 and there are 2 diff angles of depressions. i just used the sine laws twice (to get hypotenuse of angles of dep. at 37 degrees and then find the distance on land.</p>
<p>did anyone get the question with f(x) = f(-x) and there were a bunch of polynomials? (like x^5-3x^3+x=0 or something like that) I skipped it but it's been bugging me ..</p>
<p>Relative</a> Positions of Three Planes in Space. - And systems of 3 equations in 3 unknowns. -</p>
<p>Scroll down. 3 Planes can form a line or a point, just like a system of 3 equations can have one unique solution.</p>
<p>for 457/n and remainder 17 i got 0 as the answer
n = 5, remainder is 17 ....lol only now did i realize remainder is bigger than number you are dividing lol...</p>
<p>and i think 3 planes can only make a point and no line since only at the intersecting point will f(x,y,z) have same value....look at picture he linked there u can visualize</p>
<p>honestly, the "extension in 2 dimensions", i dont think anyone would expect us to account for that. i also put line/pt. i would be extremely dissappointed if i was penalized for that. </p>
<p>i omitted 4, strongly believe i got everything else right</p>
<p>durak: I did the exact same thing...</p>
<p>procrastination, u the man. thanks for the clear up</p>
<p>i think i put line, point, and ray. </p>
<p>it can't be ray right?</p>
<p>and dolcevalse, i used the law of sines, but i got some weird answer..</p>
<p>Can't be ray because planes extend infinitely.</p>
