Answer: C. ry=x(x, y) → (y, x)

Step-by-step explanation:

From the given picture, the coordinates of A = (-2,1), B(3,4) and C(-4,1)

and the coordinates of A' =(1,-2), B'(4,3) and C'(1,-4)

We can see that the x and y coordinates of ΔABC has changed their place in ΔA'B'C'.

Therefore, the rule for the given reflection is in option C.

i.e. ry=x(x, y) → (y, x) .

The answer is C because if you put
$x = - 2 \\ y = 1 \\$
Find the reflected two points which are:
$x = 1 \\ y = - 2$
They're just flipped equations

Answer:

The area of the shaded region is 125.664 square centimetre

Step-by-step explanation:

Area of the shaded region = area of the circle with radius 7 cm - area of the circle with radius 3 cm----------------(1)

Step 1: Finding the area of the circle with radius 7 cm

Area of the circle A = $\pi r^2$

On substituting the value of the radius, we get

Area of the circle A = $\pi(7)^2$

Area of the circle A = $49 \pi$ square centimetre----------------(2)

Step 2: Finding the area of the circle with radius 3 cm

Area of the circle a = $\pi r^2$

On substituting the value of the radius, we get

Area of the circle a = $\pi (3)^2$

Area of the circle a = $9 \pi$ square centimetre ----------------(3)

Step 3: Finding the area of the shaded region

Area of the shaded region = $49 \pi - 9\pi$

= $40 \pi$

= 125.664 square centimetre
