The displacement of a particle on a vibrating string is given by the equation where s is measured in centimeters and t in seconds. Find the velocity of the particle after t seconds. y = cos 3 x . f (85) ( x ) = $$−385 sin (3 x ) s ( t ) = 9 + sin( 9 π t ) 1 5 v ( t ) = $$9π5 cos (9π t ) cm/s

15. 2/2 points | Previous Answers SCalcET7 3.4.081. A Cepheid variable star is a star whose brightness alternately increases and decreases. For a certain star, the interval between times of maximum brightness is 6.1 days. The average brightness of this star is 4.0 and its brightness changes by ± 0.55 . In view of these data, the brightness of the star at time t , where t
