What is the solution of log2 (3x - 7) = 3? YOU''LL GET A MEDAL!
a. 1/3
b.4
c.5
d. 16/3

A Cepheid star is a type of variable star, which means its brightness is not constant. The relationship between the brightness of a Cepheid star and its period, or length of its pulse, is given by M = –2.78(log P) – 1.35, where M is the absolute magnitude, or brightness, of the star, and P is the number of days required for the star to complete one cycle. What is the absolute magnitude of a star that has a period of 45 days? Use a calculator. Round your answer to the nearest hundredth.
a. –5.95b. –4.60 c. 3.25 d. 4.60
