a bird (B) is spotted flying 5,000 feet from a tree (T). an observer (O) spots the bird (B) at a distance of 13,000 feet. what is the angle of depression from the bird (B) to the observer? A. 22.70 B. 44.62 C. 67.38 D. 68.96

im pretty sure its

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
