Answer:
h = 3589.9 meters ⇒ answer (D)
Step-by-step explanation:
∵ P(h) = P0 . e^(-0.00012h)
∵ P(h) = 65% of P0
∴ 
∴ 
∵ Insert <em>ln</em> in both sides
∴ 
∵<em> </em><em>ln</em>(e) = 1
∴ h = ln(0.65)/-0.00012 = 3589.9 meters
Answer:
area of trapazoid= 1/2 × b× h
so = 1/2×9×15
=1/2×135
=67.5cm
Answer:
40degres
Step-by-step explanation:
We are given with the equation
y = e^-9x with the restriction of x <span>≥ 0
If rotated about the x-axis the area of the resulting surface is
A = </span>π ∫ y² dx
Substituing
A = π ∫ (e^-9x)² dx
A = π ∫ e^-18x dx
The limits are from 0 to positive infinity.
