4. Tim is walking down the aisle of a speeding bus and tosses a coin in the air. Matthew is standing on the sidewalk outside.
a. Draw the trajectory of the coin from Tim's frame of reference.

b. Draw the trajectory of the coin from Matthew's frame of reference.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
