Answer:

The answer is B.180°.

Step-by-step explanation:

The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.

In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.

Therefore, the only option that applies is B.180°

The maximum rate of change occurs in the direction of the gradient vector at (1, 1, 1).

$T(x,y,z)=e^{-x^2-2y^2-3z^2}\implies\nabla T(x,y,z)=\langle-2x,-4y,-6z\rangle e^{-x^2-2y^2-3z^2}$

At (1, 1, 1), this has a value of

$\nabla T(1,1,1)=\langle-2,-4,-6\rangle e^{-6}$

so the captain should move in the direction of the vector $\langle-1, -2, -3\rangle$ (which is a vector pointing in the same direction but scaled down by a factor of $2e^{-6}$ ).
