Question: ASTRONOMY Astronomers use the distance modulus function M(r)=5logr-5, where M is the distance modulus and r is the distance of a star from Earth in

ASTRONOMY Astronomers use the distance modulus function M(r)=5logr-5, where M is the distance modulus and r is the distance of a star from Earth in parsecs. (One parsec is approximately 1.921013 mi, or approximately 20 trillion miles.) Round to the nearest tenth.

The distance modulus of Alpha Centauri is -1.11. How many parsecs from Earth is this star?
