The inequality that represents this is 
*Note: The sign
represents including the value following it. However, we do not want to include zero in our set, hence 
Answer:
r > 0
Step-by-step explanation:
a. r≤ 0 the equation is represented as r value is equal to zero or less than zero. So r can be zero or negative since its saying less than zero.
b. r≥ 0 the equation is represented as r value is greater than but equal to zero. So r can be zero and nonpositive.
c. r> 0 the equation is represented as r value greater than 0 which makes the answer positive.
d. r≤ ∞ the equation is represented as r value is equal to all positive integers but all negative integers.
e. r< ∞ the equation is represented as r value is all negative numbers since the inequality sign is less than
