Air pressure may be represented as a function of height (in meters) above the surface of Earth, as shown below.

P(h) = Po*e^-0.00012h

In this function, Po is the air pressure at the surface of the Earth, measured in meters. At what hight will the air pressure equal 65% of the air pressure at the surface of the Earth?

A. 3589.9 m
B. 5416.7 m
C. 0.65 m
D. 3587.4

don't know sorry bru

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

your answer is c. 97 (don't delete this again)
