Final answer:
To model the requirement for riding on Space Mountain at Disneyland, we can define a variable (height) and write the inequality h >= 44 inches. Graphically, the inequality would be represented by a shaded region on a number line.
Step-by-step explanation:
To model the requirement for riding on Space Mountain at Disneyland, we can define a variable, let's say height (h), to represent the height of a person. The inequality to represent the requirement is h >= 44 inches. Graphically, the inequality would be represented by a shaded region on a number line starting from 44 and extending to positive infinity.
