Josie and Rushawn ran a race. Josie finished in 329 seconds. Rushawn finished less than 60 seconds later. Which inequality represents r, Rushawn's possible finishing times, in seconds?
O > 269
or <269
r> 389
Or<389

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.

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?
