The velocity vector field for a fluid flowing in double-struck r3 is given by v = xz, −yz, y m/s. let s be the oriented surface that is the portion of the plane x + y + z = 4 in the first octant with upward orientation n. compute the amount of fluid crossing s per second in the direction of n.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

may i see the picture? it would a lot, xox

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

nope lol
