3. When an object is removed from a furnace and placed in an environment with a constant temperature of 80F, its core temperature is 1600 F. One hour after it is removed, the core temperature is 1110 F. a. Write an equation for the core temperature y of the object t hours after it is removed from the furnace. (Round your coefficients to four decimal places.) b. Find the core temperature 7 hours after the object is removed from the furnace. (Round your answer to one decimal place.)
