Two bricks of the same mass are each on ledges. brick 1 is 100 feet high and brick 2 is 300 feet high. brick 2 has:
1. zero times more potential energy
2. two times more potential energy
3. three times more potential energy
4. four times more potential energy
5. nine times more potential energy

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.)
