5. (12) Wind chill, W(v,T), is the perceived temperature resulting from wind, and is dependent on wind velocity (v) and actual temperature (T). Using the table below: a) Find W(25, 5). What physical quantity does this represent? b) Estimate the partial derivatives "\"25, 5) and WT(25, 5). What do these quantities represent? 0) Create a linearization L(v,T), of the function W(v,T), at the point (25,5) d) Use L(v, T), to estimate W(23.6)
