Answer:

see explanation

Step-by-step explanation:

The area of the shaded portion is the area of the outer circle subtract the area of the inner circle

area of larger circle = πr² ← r is the radius = 11

area = π × 11² = 121π

area of smaller circle = πr² ← r = 9

area = π × 9² = 81π

-----------------------------------------

shaded area = 121π - 81π = 40π m² ≈ 126 m²

Graph the function defined by f(x) = (x+21)

Inga [223]

Answer:

Step-by-step explanation:

Consider the parent function $y=|x|.$ The graph of this function is represented as red graph in attached diagram.

Now consider the function $y=|x+2|.$

Remind main translations of the graph of the function $y=f(x):$

$y=f(x-a)$ - translation a units to the right;
$y=f(x+a)$ - translation a units to the left;
$y=f(x)+a$ - translation a units up;
$y=f(x)-a$ - translation a units down.

In your case, the graph of the function $y=|x+2|$ is translated graph of the function $y=|x|$ 2 units to the left (blue graph). So, correct answer is option A.
