Evaluate the surface integral â«F. ds for the given vector field F and the oriented surface S. In other words, find the flux of F across S. For closed surfaces, use the positive (outward) orientation. F(x, y, z) = xi - zj+ yk; S is the part of the sphere x2+y2+z2=16 in the first octant, with orientation toward the origin.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

answer: b

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
