During the first week in November, Erin Mills worked 45½ hours and produced 1,275 units under a piece-rate system. The regular piece rate is $0.45 a unit. Mills had agreed with her employer prior to the performance of the work that she would be paid one and one-half times the regular piece rate for all pieces produced during the overtime hours. Assume that her production totals for the week were 1,075 pieces during regular hours and 200 pieces during overtime hours. Compute the following amounts.

a. The piecework earnings
b. The overtime earnings
c. The total earnings

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
