A small object with an initial temperature of 135 degrees Fahrenheit is dropped into a tub with a temperature of 60 degrees Fahrenheit. The function f(t)=Ce(â’kt) 60 represents the situation, where t is time in minutes, C is a constant, and k is a constant. After 6 minutes the object has a temperature of 85 degrees. What is the approximate value of k? Round to three decimal places.

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
