Help me out please asymptotes

d, b , a

Step-by-step explanation:

Diagram on left

As x → + ∞, y → + ∞, as x → - ∞ , y → - ∞ ( as explained in previous question ) d

Top diagram on right

As x → + ∞, y → 0 and x → - ∞ , y → 0

This means that as x increases to the right , y approaches the x- axis (y → 0)

and as x increases to the left, y approaches the x- axis (y → 0 ) b

Lower diagram on right

As x → + ∞, y → + ∞ and as x → - ∞, y approaches the x- axis (y → 0 ) a

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
