Question 12
(02.03, 02.04 HC)

An ice cube is freezing in such a way that the side length s, in inches, is s of t equals one half times t plus 2 comma where t is in hours. The surface area of the ice cube is the function A(s) = 6s2.

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.

in 4 days he will run   12/14

step-by-step explanation:

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
