Question

The graph represents the atmospheric pressure, in grams per square millimeter, as a function of altitude in miles above sea level.
Which statements accurately reflect this relationship?

Select each correct answer.

The atmospheric pressure is 8 g/mm2 at sea level.

The atmospheric pressure gets close to 8 g/mm2 as the altitude continues to decrease.

As the altitude decreases, the atmospheric pressure approaches 0 g/mm2 .

As the altitude decreases, the atmospheric pressure decreases.

Answer 1

Answer:

The correct option is 1. The atmospheric pressure is 8 g/mm² at sea level.

Step-by-step explanation:

In the given graph y-axis represents the atmospheric pressure, in grams per square millimeter, and x-axis represents the altitude in miles above sea level.

The y-intercept of the graph is 8. It means the atmospheric pressure is 8 g/mm² when the altitude above sea level is 0.

Therefore atmospheric pressure is 8 g/mm² at sea level and option 1 is correct.

The graph represents a decreasing function.

As the altitude in miles above sea level increases the atmospheric pressure decreases and vice versa.

As the altitude in miles above sea level increases without bound the atmospheric pressure approaches 0 g/mm².

Therefore options 2,3 and 4 are incorrect.
