The last question is to find the area

need help ASAP

12 cm²

Step-by-step explanation:

A= 1/2ah

h= 6*sin 30° = 6*1/2= 3 cm

A= 1/2*3*8= 12 cm²

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.
