Air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below.
-0.00012
P(h) = P..e
In this function, P, is the air pressure at the surface of the Earth, and his the
height above the surface of the Earth, measured in meters. At what height will
the air pressure equal 50% of the air pressure at the surface of the Earth?
A. 0.59 m
B. 2148.9 m
C. 4166.7 m
D. 5776.2 m

i would have to say it is c.

my dude, this isn't answerable due to the fact there is no question or clear desc of what you want them to do.

the linear equation will be:  

step-by-step explanation:

the site has 5 banner ads and a banner ad earns $0.005 per click.

so, the money earned by 5 banner ads per click

now, if the number of clicks is , then the amount of money earned

given that, it costs $120 a month to operate the website.

so, the linear equation that represents the monthly income will be:
