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
The hypotenuse MO is found from the Pythagorean theorem to be
MO = √(12² + 5²) = √(144+25) = √169 = 13
The sine of angle O is the ratio of the opposite side (MN=12) to the hypotenuse (MO=13). The appropriate choice is ...
