Answer:

Step-by-step explanation:
Distance Formula: 
Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:






Answer:
You need to categorize this to the form y=mx+c / y=mx+b
So,
12y=y & 3x=x
(Just let me know if u need further explanation or if this wasn't the ans. u were looking for)
Substitute 136.5 for y.




Compare this equation with 
a = 1, b = - 191, c = 8190

or

x = 126 or x = 65
Hence, the points on the curve are (65, 136.5) and (126, 136.5).
The width of the air space is the distance between these points.
Width = 
= 
= 126 - 65
= 61
Hence, width of the air space is 61m.
Step-by-step explanation:
450 - 396 = 54
(54/450) * 100% = 12%
Hence the decrease is 12%.
