The velocity of an object increases from –10 m/s to –15 m/s in 2.0 s. what is the average acceleration of the object? +2.5 m/s2 –12.5 m/s2 –2.5 m/s2 +12.5 m/s2

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.)

Can you match these to the correct definition
