This is a geometric sequence  with first term a1 = -4 and common ratio r = 4
so nth term  = a1* r^(n-1)
                   = -4 *4^(n-1)
        
                    
             
        
        
        
Answer:
The velocities after 739 s of firing of each engine would be 6642.81 m/s in the x direction and 5306.02 in the y direction
Step-by-step explanation:
- For a constant acceleration:  , where , where is the final velocity in a direction after the acceleration is applied, is the final velocity in a direction after the acceleration is applied, is the initial velocity in that direction  before the acceleration is applied, a is the acceleration applied in such direction, and t is the amount of time during where that acceleration was applied. is the initial velocity in that direction  before the acceleration is applied, a is the acceleration applied in such direction, and t is the amount of time during where that acceleration was applied.
- <em>Then for the x direction</em> it is known that the initial velocity is  5320 m/s, the acceleration (the applied by the engine) in x direction is 5320 m/s, the acceleration (the applied by the engine) in x direction is 1.79 m/s2 and, the time during the acceleration was applied (the time during the engines were fired) of the  is 739 s. Then: 1.79 m/s2 and, the time during the acceleration was applied (the time during the engines were fired) of the  is 739 s. Then: 
- In the same fashion, <em>for the y direction</em>, the initial velocity is   0 m/s, the acceleration in y direction is 0 m/s, the acceleration in y direction is 7.18 m/s2, and the time is the same that in the x direction, 739 s, then for the final velocity in the y direction: 7.18 m/s2, and the time is the same that in the x direction, 739 s, then for the final velocity in the y direction: 
 
        
             
        
        
        
Answer:
B.
Step-by-step explanation:
To have a negative slope, <em>m</em> has to be negative. Any negative slope would show up as a negative coefficient in front of <em>x</em>.
