Aparking lot charges $3 to park a car for the first hour and $2 per hour after that. if you use more than one parking space, the second and each subsequent car will be charged 75% of what you pay to park just one car. if you park 3 cars for t hours, which function gives the total parking charge? a. f(t) = 3(3 + 2(t − 1)) b. f(t) = (3 + 2t) + 0.75 ×  2(3 + 2t) c. f(t) = (3 + 2(t − 1)) + 0.75 × 2(3 + 2(t − 1)) d. f(t) = (3 + 2t) + 0.75(3 + 2t) + 0.75 × 0.75(3 + 2t) e. f(t) = (3 + 2(t − 1)) + 0.75(3 + 2(t − 1)) + 0.75 × 0.75(3 + 2(t − 1))

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?
