Answer:
The value of pressure at an altitude of 10000 ft = 10 
Step-by-step explanation:
Given data
Atmospheric pressure
= 14.7 
Pressure at 4000 ft = 12.6 
If temperature is constant then the atmospheric pressure is varies with the altitude according to law
P (h) =
------ (1)
where k= constant & h = height
12.6 = 14.7 
0.857 = 
㏑ 0.857 = - 4000 k
-0.154 = - 4000 k
k = 3.85 × 
Thus the atmospheric pressure at an altitude of 10,000 ft is
14.7 ×
----- (2)
Product of k & h is
k h = 3.85 ×
× 10000
k h = 0.385
Put his value of k h = 0.385 in equation (2) we get
14.7 × 
10 
This is the value of pressure at an altitude of 10000 ft.
Answer:
Step-by-step explanation:
If XY bisects DF at point E, then DE = EF.
Given DE = 2y and EF = 8y-3
2y = 8y-3
subtract 8y from both sides
2y-8y = 8y-8y-3
-6y = -3
y = 3/6
y = 1/2
y = 0.5
DF = DE+EF
DF= 2y+8y-3
DF = 10y - 3
DF = 10(0.5)-3
DF = 5-3
DF = 2
