An electrician earns $24 an hour for a regular work week (40) hours. she earns time and a half for overtime. the weekly wage function is 24h 36(h – 40 +960 0 h> 40 how much will she eam if she works 38.5 hours this week?

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
