David read the paper while eating breakfast and some of the information was smudged. Use the information below to find all of the missing high and low temperatures during the week. On Tuesday, the low temperature was 3 degrees colder than on Monday's low temperature. On Thursday, the high temperature was 5 degrees warmer than the low temperature on Thursday On Friday, the low temperature was 11 degrees higher than the low temperature on Saturday. TUESDAY (Low) THURSDAY (High) FRIDAY (Low) -1 because it is 2 on Monday and it is -3 degrees colder so 2 + -3 is -1 4 because it is -1 on Thursday and -1 + 5 is 4 3 because the low temperature on Saturday was -8 so -8 + 11 is 3

Find the product of (4x + 3y)(4x − 3y). 16x2 − 24xy + 9y2 16x2 − 9y2 16x2 + 24xy + 9y2 16x2 + 9y2

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?

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
