Answer:
If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational.
 
        
             
        
        
        
Answer:
A. 3.0 m/s
Step-by-step explanation:
Based on the graph, 
velocity = Area of the graph

(y : position and x : time) 
Let y1 = 2m and y2 = 14m,
 t1 = 0s and t2 = 4s
v = (14 - 2)m/(4-0)s
 = 12m/4s
 = 3.0 m/s
