In one day, there are two high tides and two low tides in equally spaced intervals. the high tide is observed to be 6 feet above the average sea level. after 6 hours pass, the 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. determine these key features of the function that models the tide: amplitude, period, frequency, midline, vertical shift, phase shift. create a trigonometric function that models the ocean tide for a period of 12 hours. what is the height of the tide after 93 hours? . i'm not the best at math and i'm scraping the bottom of the barrel right now.

Solve the system by the elimination method. x + y - 6 = 0 x - y - 8 = 0 when you eliminate y , what is the resulting equation? 2x = -14 2x = 14 -2x = 14

High school seniors with strong academic records apply to the nation’s most selective colleges in greater numbers each year. because the number of slots remains relatively stable, some colleges reject more early applicants. suppose that for a recent admissions class, an ivy league college received 2851 applications for early admission. of this group, it admitted 1033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. in the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. counting the students admitted early and the students admitted during the regular admission process, the total class size was 2375. let e, r, and d represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool.suppose a student applies for early admission. what is the probability that the student will be admitted for early admission or be deferred and later admitted during the regular admission process?
