Final answer:
A child 46 inches tall cannot ride a roller coaster with a height requirement of x > 48 inches. The inequality signifies the necessity to be taller than 48 inches, thus excluding the child.
Step-by-step explanation:
A child who is 46 inches tall cannot ride the roller coaster if the height requirement is x > 48 inches. The inequality clearly indicates that only individuals taller than 48 inches are permitted to board the roller coaster. Therefore, since 46 inches is below this minimum height requirement, the child must be at least 2 inches taller to ride.
In a similar context of physical requirements, consider scenario D where a child is involved in a roller coaster ride of a different nature, which involves physics calculations for safety during the ride. For example, calculating the force of the car seat on the child at different speeds involves understanding the centrifugal force and other aspects of physics to ensure that riders remain secured in their seats. However, these calculations are usually handled by engineers and ride designers to guarantee safety for all guests meeting the ride requirements.
