<p>its 4/9</p>
<p>you haffta account for the first and second case.</p>
<p>1 short 1 international + 1 international 1 short</p>
<p>2/9 + 2/9 = 4/9 </p>
<p>; )</p>
<p>WOOHOO!
that's what I thought.
I almost put 2/9 but I was like it can't be.
Then i thought about the other cases.</p>
<p>...watch me still not break 700 lol.</p>
<p>m = 2 for that R=kC^m one right?</p>
<p>and the interest was the $4000 somehting right?</p>
<p>I got 2 for m and 3685.58 for the interest one.</p>
<p>damn it!!! so far 2 wrong 1 skip</p>
<p>was there any other hard questons? I can't remember...</p>
<p>m is 2 and the interest is 4200 odd....</p>
<p>Interest is 3685.58 </p>
<p>3500(1+(.052/4))^4</p>
<p>How did you get something in the 4200s?</p>
<p>principal = 3500, 5.2% interest compounded quarterly</p>
<p>A = 3500(1+0.052/4)^(4) = 3685.58</p>
<p>3500 * [1 + 5.2/100]^4</p>
<p>A = Principal * [1 + R/100]^n</p>
<p>Why is it 5.2/400??? rate is a percentage.. and compunded quarterly is 4 times a year .. so n = 4</p>
<p>5.2/400 is the same thing as .052/4</p>
<p>Oh and also that probability one with 1 to 10 and get getting sum of 7.
was it .06?</p>
<p>It's compounded quarterly. You divide the interest rate by the number of times it's compounded and then the exponent is the number of times it's compounded annuals * number of years.</p>
<p>A = P(1+r/n)^(nt)</p>
<p>I got .06 for the 7 question, too.</p>
<p>i think i got .06 as well</p>
<p>i know... i think u may be right.... Interest was compounded quarterly right? at 5.2 p.a</p>
<p>And I got 24.8 for the height of the cone in the question with the equal volumes.</p>
<p>do u know how to do that 3D one? (tho I skipped)</p>
<p>I know the distance between 2 points was 1. but...ehh hate 3D</p>
<p>You mean the set of points equidistant from A(1,1,3) and B(1,2,3)? I said y = 3/2.</p>
<p>i put y=3/2 for the 3D one</p>
<p>i think the choices were x=1, y=1/2, y=1, y=3/2, z=3</p>
<p>how do u do that..arghgh</p>
