Can someone please solve this?

(1 point) The temperature at a point (:12, y, z) is given by T(a:, y, z) = 13008'59L292Z2 where T is measured in OC and 3:, y, and z in meters. 1. Find the rate of change of the temperature at the point P(2, 1, 2) in the direction toward the point Q(3, 3,3). Answer: DID-(3 f(2, 1, 2) : -(20800e/\\-9)/sqrt(6 2. In what direction does the temperature increase fastest at P? Answer: I l 3. Find the maximum rate of increase at P
