SOLVED:A Cepheid variable star is a star whose brightness alternately increases and decreases. The most easily visible such star is Delta Cephei, for which the interval between times of maximum brightness is 5.4 days. The average brightness of this star is 4.0 and its brightness changes by ±0.35 . In view of these data, the brightness of Delta Cephei at time t, where t is measured in days, has been modeled by the function B(t)=4.0 0.35 sin((2 πt)/(5.4)) (a) Find the rate of change of the brightn

SOLVED:Go to the Goddard Multimedia website and view the animation of a Cepheid variable star in a spiral galaxy (http://svs .gsfc.nasa.gov/goto?10145). Explain how astronomers use data like these to estimate the distance to the galaxy. What is actually observed, what is assumed, and what is calculated? (Review the discussion in Chapter 16 as needed.)
