Advanced Algebra II Notes 5.8 Applications of Logarithms Recall the pendulum example from Lesson 5.4. The equation y = 1.25 + .72(.954)x-10 gave the distance from a motion sensor for each swing of the pendulum based on the number of the swing. Use this equation to fin the swing number when the greatest distance was closest to 1.47 m.
Eva convinced the mill workers near her home to treat their wastewater before returning it to the lake. She then began to sample the lake water for toxin levels (measured in parts per million, or ppm) once every five weeks. Here are the data she collected: Eva hoped that the level would be much closer to zero after this much time. Does she have evidence that the toxin is still getting into the lake? Find an equation that models these data that she can present to the mill to prove her conclusion. Start with:
