1- Use a graphing utility to approximate (to three decimal places) the solutions of the following in the interval [0, 2?). (Round your answer to three decimal places.) 8 sin(x) ? x = 0

X=

Use the figure to find the exact values of sin(2u), cos(2u), and tan(2u). 5mm) = E menu) = E mm = E Cheyenne, Wyoming, has a latitude of 410 N. At this latitude, the number of hours of daylight D can be modeled by D = 2.914 sin(0.017t - 1.321) + 12.134 where t represents the day, with t = 1 corresponding to January 1. Use a graphing utility to determine the days on which there are more than 10 hours of daylight. t (Round your answers to the nearest integer.) first day t last day tThe heights .h1 and hz (in feet) above ground of two people in different seats on a Ferris wheel can be modeled by 1'1l = 26 cos(10t) + 32 and h2 = 26 cos[10(t )] + 32, 0 S t S 2 6 where t represents the time (in minutes). When (in min] are the two people at the same height? (Round your answers to two decimal places. Enter your answers as a commaseparated ist.) t = min Rewrite the following as a sum or difference. 8 sin(50) cos(40)
