8) Poaching is causing a population of elephants to decline by 5% per year. Use the approximate half-life formula to determine the fraction that remains in 59 years if there are 8661 elephants today. A) 8243 elephants B) 467 elephants C) 4829 elephants D) 18,250 elephants 14) In 1995 the United States recovered 20% of its municipal solid wastes through recycling, up from 17% in 1990. Let P represent the percentage recycled and t the number of years since 1990. Based on these two data points, create a linear equation for the function that describes how P varies as a function of time. A) P = -0.6t + 7 B) P = 0.6t + 17 C) P = 0.3t - 17 D) P = 0.6t + 24
