Answer:
A. China
Step-by-step explanation:
The ordered pair that represents the vector would be BC = (-6,5). The magnitude of vector WX for W and X would be the square root of 145.
Answer:
b
Step-by-step explanation:
Like 6 minutes or somthin
The surface area is given by

since
. To compute the integral, first let

so that
, and the integral becomes


Next, let

so that
. Then

so the integral becomes


Rewrite the integrand with

so that integrating the first term boils down to

where we substitute
. Since

the first term in this integral contributes


The second term of the integral contributes

The antiderivative of
is well-known (enough that I won't derive it here myself):

so this latter integral's contribution is

Then the surface area is
