After the Chermobyl nuclear reactor accident in 1986, large areas surrounding the site were contaminated with 90 Sr. If 15 g (micrograms) of 90Sr is present in a sample, the function 1 1/28.9 gives the amount A (1) (in g) present after t years.

He estimates that the resale value V(t) (in $1000) of the tractor t years after purchase is 80% of its value from the previous year. Therefore, the resale value can be approximated by V)-1370.8 4.2 Section Exercise 61 Part 1 a. Find the resale value 6 yr after purchase. Round to the nearest $1000. Do not round intermediate calculations. As The resale value of the tractor 6 yr after purchase will be approximately s 36000 Li Part 2 out of 2 b. The farmer estimates that the cost to run the tractor is $18/hr in labor, $36/hr in fuel, and $24/hr in overhead costs (for maintenance and repair). Estimate the farmer's cost to run the tractor for the first year if he runs the tractor for a total of 800 hr. Include hourly costs and depreciation. Do not round intermediate calculations. Round your final answer to the nearest $1000. It costs the farmer S to run the tractor for 800 hr during the first year
