Led bulbs are six times as efficient as incandescent bulbs. if a household replaced ten 100-watt bulbs with led bulbs, how many watts would be saved? 833 watts 400 watts 1700 watts 175 watts 600 watts

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.)
