Hot air balloon 1 is 10 meters above the ground, rising 15 meters per minute, and hot air balloon 2 is 150 meters above the ground descending 20 meters per minute.
in how many minutes will the balloons be at the same height?
how high will the balloons be at that time?
(let x represent the time and y represent the height)

The function models the number of accidents per 50 million miles driven as a function

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?
