A heat source is removed from a thermal tile, causing the temperature to drop. If the rate of change of the temperature T of a thermal tile is inversely proportional the square root of time t, where t ≥ 0, write a differential equation that models the situation.

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?
