Answer:
Step-by-step explanation:
dP/dh = kP
dP/P = k dh
ln P = kh + C
Now, using the points given,
ln 101.5 = C, so C = 4.62
ln 87.3 = k*1000 + 4.62
k = -0.00015
So, we have
ln P = -0.00015 h + ln 101.5
P = 101.5 e^(-0.00015h)

Answer:
y ≥ x - 2 and x + 2y < 4
Step-by-step explanation:
There are two lines graphed.
The dotted line passes through (0,2) and (4,0), then:
<u>slope (m)</u>: (0 - 2)/(4 - 0) = -1/2
<u>y-intercept (b)</u>: 2
<u>equation</u>:
y = mx + b
y = -1/2x + 2
multiplying by 2 at both sides, we get
2y = -x + 4
x + 2y = 4
The inequality is x + 2y < 4 because points below this line are shaded and points on the line are not included.
The solid line passes through (0,-2) and (2,0), then:
<u>slope (m)</u>: (0 - (-2))/(2 - 0) = 1
<u>y-intercept (b)</u>: -2
<u>equation</u>:
y = x - 2
The inequality is y ≥ x - 2 because points above this line are shaded and points on the line are included.
