Question

use the graph on the right to answer the following questions.
a. estimate the pressure at altitudes of 9,000 feet, 18,000 feet, and 29,000 feet.
b. estimate the altitudes at which the pressure is 23, 19, and 11 inches of mercury.
c. estimating beyond the boundaries of the graph, at what altitude do you think the atmospheric pressure reaches 5 inches of mercury? is there an altitude at which the pressure is exactly zero? explain your reasoning.
a. the pressure at 9,000 feet is 21 inches of mercury, the pressure at 18,000 feet is 14 inches of mercury, and the pressure at 29,000 feet is 10 inches of mercury. (round to the nearest integer as needed.)
b. the altitude for which the pressure is 23 inches of mercury is feet, the altitude for which the pressure is 19 inches of mercury is feet, and the altitude for which the pressure is 11 inches of mercury is feet. (round to the nearest thousand as needed.)

Explanation:

Step1: Locate values on graph

Locate the given pressures on the y - axis and find the corresponding x - values (altitudes) on the graph.

Step2: Estimate altitudes

For a pressure of 23 inches of mercury, by looking at the graph and estimating the x - value corresponding to y = 23, we get approximately 3000 feet.
For a pressure of 19 inches of mercury, estimating the x - value corresponding to y = 19, we get approximately 6000 feet.
For a pressure of 11 inches of mercury, estimating the x - value corresponding to y = 11, we get approximately 15000 feet.

Answer:

The altitude for which the pressure is 23 inches of mercury is 3000 feet, the altitude for which the pressure is 19 inches of mercury is 6000 feet, and the altitude for which the pressure is 11 inches of mercury is 15000 feet.
