Which statement completes step 5 of the proof? Step 1 is parallel to the y-axis, and is parallel to the x-axis. Step 2 ΔJKL was rotated 90° clockwise to create ΔJ'KL'. Point K did not change position, so it remains point K. Therefore, ΔJKL ≅ ΔJ'KL'. Step 3 is perpendicular to the y-axis, and is perpendicular to the x-axis. Step 4 lies on line f and has a slope of 3. Step 5 ? Step 6 The product of the slopes of and is −1; therefore, lines f and g are perpendicular. lies on line g and has a slope of . lies on line g and has a slope of . lies on line g and has a slope of . lies on line g and has a slope of .

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?
