Which equation represents the vertical asymptote of the graph?

There is a hidden electric fence of sorts where the graph slowly approaches this vertical line but never touches or crosses it. It might help to draw in a dashed vertical line through -8 on the x axis.

A vertical asymptote occurs when a division by zero error happens. For instance, the equation y = 1/(x+8) has a division by zero error when x = -8 since x+8 = -8+8 = 0 is in the denominator.

264 ft/sec

Step-by-step explanation:

We need to use the conversion factors

5280 ft/ 1 mi, 60 min/ 1 hr , and 60 sec/1 min

180 miles         1 hour               1 min        5280 ft

*  * *

hour                60 minutes       60 sec      1 miles

The hours, minutes and miles cancel are we are left with ft/sec

180 *5280        ft

*  

60*60                 sec      

264 ft/sec
