Find the area of the semicircle A. 18.84 square cm.

B. 56.52 square cm.

C. 113.04 square cm.

D. 37.68 square cm.

hi, i am not sure about this one but i think its d,

hope this !

-4

step-by-step explanation:

answer: x=3 and y=4

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.
