K Prehistoric cave paintings were discovered in a cave in France. The paint contained 23% of the original carbon-14. Use the exponential decay model for carbon-14, A Age 0.000121t, to estimate the age of the paintings. The paintings are approximately years old. (Round to the nearest integer.)

A desalinization process is eliminating 20% of the salt from seawater every 10 minutes. There are initially 450 g of salt in 10 liters of water. Find an exponential function for A, the grams of salt in the 10 liters of seawater t minutes after the process has begun. A= ? Use the model to predict the amount of salt (in grams) in the seawater after 35 minutes. Round to the nearest whole number. ? g
