If \(0 < x < y < 10\), then \(A(x, y)\) represents the area of the region bounded by the number line, the semi-circle, and the vertical segments at \(x\) and \(y\), as indicated by the shaded region.
\(0 < a < b < c < 10 \)
Quantity A |
Quantity B |
\(A(a, b) + A(b, c)\) |
\(A(a, c)\) |
A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Kudos for the right answer and explanation

Refer attached figure
A(a,b) is Area of the shaded region in blue + A(b,c) is the area of the shaded region in green
Clearly sum of these two is equal to the area of the shaded region in red = A(a,c)
So, both quantities are equal.
So, Answer is C
Hope it helps!

If you visualize the question in your mind then: A(a,b)+A(b,c)= area between a and c
A(a,c)= area between a and c
So the answer is C.
A(a,c)= area between a and c
So the answer is C.
