Answer:

$k=-2$

Step-by-step explanation:

Let's write the left hand side as a negative power, and 9 as a power of 3:

$3^-^k=3^2$ At this point, for the equality to still stand, the exponents have to be equal:

$-k = 2 \rightarrow k=-2$

(1/3)k = 9
3 -k = 3 2
-k=2
K=-2

When s is the open hemisphere x 2 + y 2 + z 2 = 1, z ≤ 0 , oriented by the inward normal pointing to the origin, then the bounda

Anit [1.1K]

The figure below shows a diagram of this problem. First of all we graph the hemisphere. This one has a radius equal to 1. Given that z ≤ 0 a sphere will be valid only in the negative z-axis, that is, we will get a half of a sphere that is the hemisphere shown in the figure. We know that this hemisphere is oriented by the inward normal pointing to the origin, then we have a Differential Surface Vector called N, using the Right-hand rule <span>the boundary orientation is </span>counterclockwise.

Therefore, the answer above False
