Question 65795: The greenhouse cools down after the sun sets to the following formula T=85-(n^2-1)/(n+1), where n is the number of hours the sun after the stops hitting the building. In December the average number of hours that the sun does not hit the greenhouse is 16.25. How cool should we expect the greenhouse to get by sunrise of an average day in December?

Question 65794: The number of fish that jon catches is dependent upon the lures he uses. He also uses lots of expensive lures. Here in S.C each fisherman can use 2 poles at one time so jon can use two different lures. If L^1 represents the number of fish caught per hour for the first lure on the pole that he holds and if L^2 represents the number of fish caught per hour for the lure on the pole that he puts on the "dummy" holder, then the formula below represents the relation between the two lures used and the total number of lures lost per hour using the 2 poles (C is the rate of lures lost per hour using both poles) If the combined lost rate and the rate for fish on lure 2 are known, write a function for the rate of fish on the first lure (solve the equation for L^1)
1/C=1/L^1+L^2/L^1
