With the Hubble Space Telescope, you discover a Cepheid variable star in a nearby galaxy that has a period of 30 days.If nearby Cepheids follow a period-luminosity that relates the absolute magnitude to the period of pulsation via 
, where P(days) is the star's period in days, then what is this Cepheid's luminosity? Recall that the Sun's absolute magnitude is M = 4.83.If the apparent magnitude of the Cepheid is 25, what is this galaxy's distance in parsecs?
