please answer during normal breathing about 11% of the air in the lungs is replaced with each breath. write an exponential decay model for the amount of original air left in the lungs if the initial amount of air in the lungs is 550 milliliters. how much of the original air is present after 30 breaths?

a = ^x

the amount of air left after 30 breaths is milliliters

ian gone lie this got me confused

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

answer: y=0 if that is what u r looking for

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).
