Step-by-step explanation:
We have the graph of f(x).
In order to find f(0), we simply need to find the y-coordinate of the coordinate when x is 0.
From the graph, we can see that there is a point at (0,1).
In other words, when x is 0, f(x) is 1.
Therefore:

Answer:
(0.4) . (0.1) = (0.04)
Step-by-step explanation:
The spoke of the wheel serves as the radius of the circle.
To solve for the circumference of the circle, we use this formula:
C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r
6.69 inches = r
The length of each spoke is 6.69 inches.
