Let the temperature T in degrees at the point (x,y,z), with distances measured in cm, be T(x,y,z)=3x – 4y +3z. Let q be the real numbe such that the rate at which the change in temperature at (-2,0,3) per unit change in the distance travelled in the direction of the vector (1,q,1> is 4°/cm. Find q. (Note that the "direction" of a vector is always a unit vector "pointing the same way.") none of the other answers -7/40 17/56 1/12 1/2
