Josephine started a business selling cosmetics. she spent $4500 to obtain her merchandise, and it costs her $200 per week for general expenses. she earned $550 per week in sales. what is the minimum number of weeks it will take for josephine to make a profit? write an inequality to model the problem.

a.)550w > 4500 + 200w

b.)200w > 4500 + 550w

c.) 550w < 4500 + 200w

d.)200w 4500 + 550w

Just tell me how to set up the equation.

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?
