Pre calc!! the function f(t)=20sin(10t)+25 models the height of a specific seat on a ferris wheel above the ground at time, t. Over what time, t, is the person riding at least 40 feet in the air?

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
