Jackie buys 3 hot dogs and 1 pretzel from a restaurant for $12.25. Sylvia buys 2 hot dogs and 4 pretzels from the same restaurant for $16.50. Part A

Which system of equations can be used to determine the price of a hot dog, h, and a pretzel, p, at the restaurant?

​​​​​​2h + 1p = 12.25

3h + 4p = 16.50

​​​​​​ 2 h + 1 p = 12.25 , , 3 h + 4 p = 16.50,

2h + 1p = 12.25

3h + 4p = 16.50

2 h + 1 p = 12.25, , 3 h + 4 p = 16.50,

2h + 4p = 12.25

3h + 1p = 16.50

2 h + 4 p = 12.25 , , 3 h + 1 p = 16.50,

3h + 1p = 12.25

2h + 4p = 16.50

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?
