The density of atmosphere (measured in kilograms/meter3) on a certain planet is found to decrease as altitude increases (as measured from the planet's surface). What type of relationship exists between the altitude and the atmospheric density, and what would the atmospheric density be at an altitude of 1,291 kilometers? a. Inverse plot, 0. 45 kilograms/meter3 b. Inverse plot, 0. 51 kilograms/meter3 c. Quadratic plot, 1. 05 kilograms/meter3 d. Inverse plot, 1. 23 kilograms/meter3 e. Inverse plot, 0. 95 kilograms/meter3.
