An ice cube is freezing in such a way that the side length s, in inches, is s(0) 1)=2+2, +2, where t is in hours. The surface area of the ice cube is the function A(s) = 6s.
Part A: Write an equation that gives the volume at t hours after freezing begins.
Part B: Find the surface area as a function of time, using composition, and determine its range.
Part C: After how many hours will the surface area equal 216 square inches? Show all necessary calculations.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
