Skylar needs to buy a pair of dress pants for $40, a shirt for $30, and a tie for $20. skylar has three coupons. the first coupon gives him x percent off on a shirt. the second coupon gives him y percent off on the dress pants. the third coupon gives him z percent off on his total purchase. he cannot combine the coupon for the total purchase with the other two coupons. these expressions give both possibilities for the total cost of skylar's purchase after the coupons are applied. the variables represent percentages as decimals. (1−x)30+(1−y)40+20 (1−z)(40+30+20) which part of the expression represents the percent that skylar will pay for the dress pants if he uses the dress pants coupon?

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?
