Three semicircles are placed in a rectangle, as shown below. The length of the rectangle is 30 m . Find the area of the shaded region. Use the value 3.14 for π, and do not round your answer.
Be sure to include the correct unit in your answer.

step-by-step explanation:

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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.
