To determine how long it takes for the ball to go down through the hoop, you would typically analyze the intersection point of the two paths represented by the solid parabola and the dotted line on the coordinate plane.
Since I cannot see the actual image or the specific details of the intersection point, here are guidelines you could use to find the answer based on your observation:
- Identify the intersection points of the parabola \( b(s) \) and the line \( h(s) \).
- Read off the time value \( s \) at the intersection point, which represents when the ball reaches the hoop.
- Compare the value you find to the provided options.
If, by reviewing the graph, you find that the ball intersects the hoop at approximately 18 seconds, select that option; if it intersects closer to 8 seconds, then select that one, and so forth.
Based on the provided responses:
- 18 seconds
- 8 seconds
- 17.9 seconds
- 17 seconds
Please use the graph's details to choose the most accurate response. If you have any more specific details from the image, feel free to share!
