Answer:

21.5cm²

Step-by-step explanation:

First you find out the Area of the square itself which is 100cm² (squared). Then you Find the Area of the circle. The formula to find the area of a circle is  π  × Radius². So you find the diameter of the circle (which is 10) and divide that by 2 to find the radius. So the radius is 5 but then you need to square 5 which is 25. Then you multiply 25 with pi which is 78.5 so the area of the circle is 78.5cm². Now what you have to do is subtract the area of the square and the area of the circle to find the area of the shaded region. 100-78.5 is 21.5cm ² and that is the answer.

The graph shows the function f(x).
Lerok [7]

The equation that represents the given data is  \RM \\f(x) = -\sqrt[3]{-x} , Option D is the correct answer.

<h3>What is a Function ?</h3>

It is a statement where two variables , one dependent and one independent are related.

It is given that

a cube root function goes through (8, 2), has an inflection point at (0, negative 1), and goes through (8, negative 3).

The equation given in the options are

\rm f(x) = -\sqrt[3]{x} \\f(x) = -\sqrt[3]{x-1} \\f(x ) =-\sqrt[3]{-x} -1 \\f(x) = -\sqrt[3]{-x}

The function goes through (8,2)

Substituting the values

f(x) = -2

f(x) = \sqrt[3]{7}

f(x) = -3

f(x) = 2

The equation that represents the given data is

\RM \\f(x) = -\sqrt[3]{-x} , Option D is the correct answer.
