An ice cube with a side length of 14 cm is melting. The equation for the volume of the melting ice is modeled by the function V(t)=(14−0.5t)^3 where t is in minutes. What is the AVERAGE RATE of change for the volume of the ice cube over the first 6 minutes?

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?
