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.

Adaylily farm sells a portion of their daylilies and allows a portion to grow and divide. the recursive formula an=1.5(an-1)-100 represents the number of daylilies, a, after n years. after the fifth year, the farmers estimate they have 2225 daylilies. how many daylilies were on the farm after the first year?
