Beginning on January 1, park rangers in Everglades National Park began recording the water level for one particularly dry area of the park. The water level was initially 2.5 ft and decreased by approximately 0.015 ft/day. a. Write a function representing the water level L x (in ft), x days after January 1. b. Write an equation for L − 1 x . c. What does the inverse handier, represent in the context of this problem? d. Evaluate L − 1 1.9 and interpret its meaning in context.

Prices of diamonds are determined by what is known as the 4 Cs: cut, clarity, color, and carat weight. The prices of diamonds go up as the carat weight increases, but the increase is not smooth. For example, the difference between the size of a 0.99-carat diamond and a 1-carat diamond is undetectable to the naked human eye, but the price of a 1-carat diamond tends to be much higher than the price of a 0.99 diamond. In this question, we use two random samples of diamonds, 0.99 carats and 1 carat, each sample of size 23, and compare the average prices of the diamonds. In order to be able to compare equivalent units, we first divide the price for each diamond by 100 times its weight in carats. That is, for a 0.99-carat diamond, we divide the price by 99. For a 1 carat diamond, we divide the price by 100. The distributions and some sample statistics are shown below

The average number of weekly social media posts varies jointly with the poster's yearly income (in thousands) and inversely with their age in years. If a 60-year-old person with an income of $100,000 posts an average of 300 times in a week, what is the value of k?
