Let s be the portion of the plane z = 2 - 2x - y which lies in the first octant. let c be the boundary curve of s, oriented counterclockwise as seen from above and let f be the vector field x i + y j + xyz k. evaluate integral_cf middot dr a) directly as a line integral, and b) as a surface integral, by using stokes' theorem.

whatvare the choices

step-by-step explanation:

i think the answer is d im not sure

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

what is the rest of the question? ?
