The diagram gives the dimensions of a swimming pool, what will be the approximate area of the cover

Step-by-step explanation:

if we wouldnt have the semicircle, all would be easy...

Area , A=10*30=300 ft^2

the semicircle has a diameter d=12 ft, than r=6

Area of the circle is Ac=3.14*r^2=113.10 ft^2

we need half of that

113.10/2=56.55

the area of the cover would be

300-56.55=243.45 ft^2

28

step-by-step explanation:

because that's the answer

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.
