A car moves a distance of 6km due north, then moves 5km due east, then 4km due north due east it stopped for a while before moving 7km due south and it finally stopped at a point 5km due west from it last position. Calculate the distance covered by the car and its direction from its starting point.​

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.)
