which of the following situations can be modeled with a periodic function?\n○ the height of a football after it has been thrown\n○ the height of a person riding on an escalator\n○ the height of a building after it has been constructed\n○ the height of a pebble stuck in the tread of a tire

Answer

Brief Explanations:

A periodic function repeats its values at regular intervals. For the height of a football after it has been thrown, it follows a parabolic - like path and does not repeat regularly. The height of a person on an escalator changes linearly. The height of a building after construction is a constant. However, as a tire rotates, the height of a pebble stuck in its tread will repeat as the tire makes full rotations, which can be modeled by a periodic function.

Answer:

the height of a pebble stuck in the tread of a tire
