Step-by-step explanation:

both  A and B are equivalent

The value of the constant is 0.8

Explanation:

The graph has the following properties:

Horizontal-axis (independent variable): width

Vertical-axis (dependent variable): height

Points on the curve:

       (0.5, 1.6), (0.8, 1), (1.6, 0.5), and (2, 0.4)

The equation represented by the graph is an inverse variation:

Height = constant / width.

From that equation, you can solve for the contstant:

constant = height × width

Now, you can take any ordered pair to find the constant:

(0.5, 1.6) ⇒ constant = 0.5 × 1.6 = 0.8

(0.8, 1) ⇒constant = 0.8 × 1 = 0.8

(1.6, 0.5) ⇒ constant = 1.6 × 0.5 = 0.8

(2, 0.04) ⇒ constant = 2 × 0.4 = 0.8

Thus, you have obtained that the constant is 0.8.
