Stephan has a set of plans to build a wooden box. He wants to reduce the
volume of the box to 192 cubic
inches. He would like to reduce each
dimension by the same amount. The
plans call for the box to be 12 inches
by 10 inches by 8 inches. Write and
solve a polynomial equation to find
out how much Stephan should take
from each dimension.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

Iwill give you ! what is the measure of ∠v ?
