Nectar foraging by bumblebees suppose that, instead of the specific nectar function in example 2, we have an arbitrary function n with ns0d − 0, nstd > 0, n9std . 0, n0std , 0, and arbitrary travel time t.
(a) interpret the conditions on the function n.
(b) show that the optimal foraging time t satisfies the equation n9std − nstd t 1 t
(c) show that, for any foraging time t satisfying the equation in part (b), the second derivative condition for a maximum value

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
