<p>Average speed
(2 x speed1 x speed2)/(speed1 + speed2)</p>
<p>Inversely proportional. work x time = work2 x time2 ( i think)</p>
<p>Pythagorean Thm a^2 + b^2 = c^2</p>
<p>Cube, the diagonal length x rad3</p>

<p>This is for tomorow's SAT soo those of you who can help, plaease do!!!</p>
<p>Have the quadratic formula in your calculator, it helps. look online how to program it. its very easy. know permutation vs. combination-very small subject but it always comes up. know distance formula-again program into calculator if you can. (i like distance, midpoint, and quadratic formulas) </p>
<p>Know all the stuff that they put in the front by heart. You dont want to be referring to it during the test. waste of time.</p>
<p>I forgot when to use the pythagoren thm! I know C always = the biggest side...</p>
