recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.

 
        
             
        
        
        
Answer:
5 meters per second
Step-by-step explanation:
First you must find the slope of the graph. Take the rise/run of the function. The graph starts at 8500 meters and goes down to 7500 meters in 200 seconds. the difference between the change in meters is 1000 meters and the change in seconds is 200 seconds. That is 1000/200. This can be simplified to 5/1 which is 5 meters per second.
 
        
                    
             
        
        
        
Answer:
[See Below] 
Step-by-step explanation:
❶ It is irrational because to make it repeating it must be <u>EXACT</u>. In this case it is adding a 0 after every 1. So it'd be irrational since it doesn't have an end. 
❷ Irrational because no one knows the end of pi. It doesn't have an ending so therefore irrational.
