Question 3 of 20
Air pressure may be represented as a function of heiglft (in meters) above the
surface of the Earth, as shown below.
P(h) = P..e
-0.00012h
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 65% of the air pressure at the surface of the Earth?
O A. 0.65 m
B. 3587.4 m
O C. 5416.7 m
D. 3589.9 m

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
