The average price paid by the synfuel industry for a short ton of coal between 2002 and 2005 can be modeled as P(t) 1.4t2- 6.1t33.5 dollars where t is the number of years since the beginning of 2000 (a) Use the limit definition of the derivative to develop a formula for the rate of change of the price of coal used by the synthetic fuel industry. P'(t)= dollars per year (b) How quickly was the price of coal used by the synthetic fuel industry growing in the middle of 2005? X dollars per year 7.9
