Answer:
6) m = (1,008 - 999)/(18 - 36) = -9/18
= -1/2
y = (-1/2)x + 1,017
7) f(12) = (-1/2)(12) + 1,017 = -6 + 1,017
= 1,011 mb
f(72) = (-1/2)(72) + 1,017
= -36 + 1,017 = 981 mb
8) x y
0 1,017
18 1,008
36 999
84 975
9) f(40) = (-1/2)(40) + 1,017
= -20 + 1,017 = 997 mb
10) As time increases, the atmospheric pressure of a hurricane decreases (by 1/2 millibar per hour).
