The moment you drive a new car off the lot , it's already worth less than you paid for it. Say you bought a new car for $28,000 and after 1 year the car was worth $26,040. A) write an equation that can be used to model this scenario.

B) by what percent is the car’s value depreciating by each year?

C) how many years will it take until the car is worth less than $10,000?

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?
