p=14.63⋅0.8

Atmospheric pressure, measured in pounds per square inch p, s, i is the force exerted by Earth's atmosphere over a given area. The atmospheric pressure, p, exerted on an airplane flying at an altitude of a miles above sea level can be approximated by the model shown above. What is the best interpretation of 0.8

the real answer is For each mile that the altitude increases, the atmospheric pressure increases 20\%20%.

Well, 0.8 is like that one friend who always says they're going to arrive at a certain time, but really shows up 20 minutes later. It's just a proportionality factor that helps us approximate the atmospheric pressure at a given altitude. In this case, it's saying that the atmospheric pressure decreases by 20% for every mile above sea level. So, if we want to find the pressure at a certain altitude, we multiply 14.63 (which represents the pressure at sea level) by 0.8 raised to the power of the altitude in miles. It's like a mathematical "get well soon" card for the pressure up there!

To interpret the value of 0.8 in the given model, we can refer to the equation:

p = 14.63 * 0.8

In this equation, p represents the atmospheric pressure in pounds per square inch exerted on an airplane flying at an altitude of a miles above sea level.

Since the question asks for the interpretation of 0.8, we can conclude that 0.8 is a coefficient or a multiplier in the equation. In this context, it is best interpreted as the proportion or the percentage of the atmospheric pressure at sea level.

To calculate the atmospheric pressure at the given altitude, one would multiply the base pressure of 14.63 pounds per square inch by 0.8. This means that the airplane will experience approximately 80% of the atmospheric pressure at sea level.

Therefore, the interpretation of 0.8 is that it represents the proportion or percentage of the atmospheric pressure at sea level that the airplane experiences at the given altitude.
