Question

at the county fair, grace took a ride in a hot - air balloon. it was a tethered balloon, which means the balloon stayed tied to the ground so that it didnt drift too high or too far. grace floated up into the sky until the tether was fully unrolled. she stayed up there a while enjoying the scenery, and then she came back down. which graph could show graces height above ground over time?

Explanation:

Grace's height - time graph should have three phases: ascending (until tether is fully unrolled), constant (staying up), and descending (coming back down). The first graph only has ascending and descending. The second graph has ascending, constant, and descending which matches the description.

Answer:

The second graph.
