Researchers in Antarctica discovered a warm sea current under a glacier that is causing the glacier to melt. The ice shelf of the glacier had a thickness of approximately 450 m when it was first discovered. The thickness of the ice shelf is decreasing at an average rate of 0.06 m per day. Which function can be used to find the thickness of the ice shelf in meters x days since the discovery? A. t(x) = 450 - 0.06x B. t(x) = -0.06(x + 450) C. t(x) = 450 + 0.06x D. t(x) = 0.06(x + 450) https://www.schoolobjects.com/awarev2/assessments/author/edit/3264/questions?print=1 2/8 10/18/24, 11:05 AM Draft - Mid Unit 4 Assessment 3.
