The square of the orbital period of a planet is proportional to the cube of its distance from the Sun. This is expressed in the formula T^2=a^3, where T is time, measured in years, and a is distance, measured in astronomical units (1 astronomical unit is the mean distance of Earth from the Sun). Use this information to answers questions 7-9. 7) Express a as a function of T. Express T as a function of a. 8) Pluto's orbital period...
