In Steinhatchee in July, high tide is at noon. The water level is 5 feet at high tide and 1 foot at low tide. Assuming the next high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for Steinhatchee's water level in July as a function of time (t). f(t) = 6 cos pi over 2 t + 2 f(t) = 2 cos pi over 2 t + 3 f(t) = 2 cos pi over 6 t + 3 f(t) = 6 cos pi over 6 t + 2

Maria needs to buy shoes for $50, jeans for $40, and a shirt for $20. She has a coupon that gives her a discount of x percent on shoes. She has a second coupon that gives her a discount of y percent on jeans. The third coupon gives her a discount of z percent on her total purchase. She cannot combine the coupon for the total purchase with the other two coupons. These expressions give both possibilities for the total cost of Maria's purchase after the coupons are applied, the variables represent the percentages as decimals.
