Question

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 =

5 + t
, y = 4 +

1
4
t,

where x and y are measured in centimeters. The temperature function satisfies

Tx(3, 5) = 9

and

Ty(3, 5) = 7.

How fast is the temperature rising on the bug's path after 4 seconds? (Round your answer to two decimal places.)
