. 4. For each quadratic equation, decide whether it has two solutions, one solution, or no solutions. Explain how you know. r2 = 16 a. b. x(x + 2) = 0 C. (r-3)(x-3) = 0 Solution:​

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).
