I need answers to these

1. When a new item is purchased, its value typically decreases overtime. We call this depreciation. Vehicles. computers, and machinery are all examples of items that depreciate in value. The value of a sports car is given by the equation V = 35000(0.85)\" + 1000, where lit'is the value in dollars, and n is the age of the car. in years. a. Use the equation to answer the following questions. i. How long will it take for the value of the car to reach $5000? ii. How much value does the car lose over the rst ten years? iii. Does the value of the car ever reach $0? Explain. b. Do you think all cars depreciate at the same rate? What factors inuence the rate of depreciation? 2. The population of Humpback whales was once thought to be as high as 125 000. although this number was drastically reduced due to whaling. New whaling laws have allowed the population to increase again. Since 19T9, the population has experienced exponential growth that can be modelled by the equation P = 7500(1.031)". where P represents the population. and n represents the years since 1979. (i.e. for 19?9, n = Q) 3. Use the equation to estimate the population in the years 1979, 1985, and 1995. b. According to the mathematical model, in what year will the population reach 20,000 whales? c. Give reasons why this model may not accurately predict the future population
