Answer:
Rate of change 
C per meter.
Step-by-step explanation:
Given,
Then,
Change of temperature at the point say, 
along the direction say, 
is,
![\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}](https://tex.z-dn.net/?f=%5CBig%5BuT_%7Bx_2%7D%2BvT_%7By_2%7D%2BwT_%7Bz_2%7D%5CBig%5D_%7B%28x%2Cy%2Cz%29%7D)
=
Hence the rate of change of temperature is C per meter.
Answer:
$223,600
Step-by-step explanation:
1. Multiply 520000 by 0.19 and get an answer of 98800. This is how much by which the car depreciates every year.
2. Now multiply 98800 by 3 (years). Now your answer would be 296400.
3. Now minus the depreciated value from the original value which is 520000-296400=223600.
Not sure about the answer but I hope this helped a bit
