A large cube of unobtainium (not a real element) is placed at 145°C and melts in exactly one hour. The cube gradually melts faster and faster, meaning that its volume is decreasing faster and faster. Which of the following functions could model the proportion of unobtainium which has melted (please provide explanation for each example and justify why it is the right/wrong answer) from t=0 to t=1 hour? (A) √(t) (B) t (C) (1/2)^(2t) (D) (e^(t)-1)/(e-1)

All edges of a cube are growing at the same rate. The length, l, in cm of each edge of the cube at t minutes is given by the function l = √(2t + 1). a) Express the volume of the cube as a function of time, t. b) Express the surface area of the cube as a function of time, t.. c) Calculate the volume and the surface area of the cube at t = 4 minutes.

All edges of a cube are growing at the same rate. The length, ℓ, in cm of each edge of the cube at t minutes is given by the function ℓ = √2t + 1. a) Express the volume of the cube as a function of time, t. b) Express the surface area of the cube as a function of time, t. c) Calculate the volume and the surface area of the cube at t = 4 minutes. Volume = Surface area =
