Answer:
The pressure at 4000 m is about 59 kilopascals
Step-by-step explanation:
The equation is of the form
y= a b^x
where a is the initial value, b is 1 - percent decrease, and x is the number of 1000 m increases
a = 96 kilopascals
b = 1- 11.4%
=1-.114
= .886
y = 96 (.886)^x
We go up 4000 m so x = 4000/1000 = 4
y = 96(.886) ^4
y = 59.156997121536
The pressure at 4000 m is about 59 kilopascals
Answer:
Step-by-step explanation:
Suppose the atmospheric air pressure at sea level is about 96 kilopascals.
For every 1000-m increase in altitude, the pressure decreases about 11.4%.
The approximate pressure at an altitude of 1000 m = 96*(1-11.4%) = 96*0.886
The pressure at an altitude of 2000 m is = 96*0.886*0.886
The pressure at an altitude of 4000 m is = 96*0.886*0.886*0.886*0.886
= 59.157 kilopascal
