Final answer:
The inequality representing the maximum velocity of 35 meters per second of a baseball thrown by a high school pitcher is V ≤ 35, indicating that the velocity can be at this value but not exceed it.
Step-by-step explanation:
The inequality that symbolizes the velocity of the baseball thrown by a high school pitcher with the hardest speed possible of 35 meters per second is V ≤ 35. The symbol '≤' represents 'less than or equal to', which means that the velocity of the baseball can be up to 35 meters per second but not exceed this value. This inequality takes into account that the pitcher may throw at varying speeds up to their maximum capability.
