A horse was grazing at the top of a small hill. The horse got thirsty and ran toward a
river at the bottom of the hill.
Complete the statement. Assume that the horse's mass did not change
The gravitational potential energy stored between the horse and Earth
as the horse ran toward the river.

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.)
