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

V(cylinder)=πR²H
Radius of the cylinder R=x, height of the cylinder H=y.
We can write for the cylinder
V(cylinder)=πx²y
V(cone) =(1/3)πr²h
Radius of the cone r=2x.
We can write for the cone
V(cone)= (1/3)π(2x)²h=(1/3)π *4*x²h
V(cylinder) =V(cone)
πx²y=(1/3)π *4*x²h
y=(4/3)*h
h=(3/4)*y
Answer:
x=64
y=54
Step-by-step explanation:
3x+4y=24 4(24-4y\3)+3y=22
x=24-4y/3 96-12y\3+3y=22
x=24-4(54)/3
x=-64 96/3-22=3y/3
y=54
