Question 124970: Hi tutor,
Thanks you for helping me....
1)Bear population. To etimate the size of he bear population on the keweenam Peninsula, conservationist capture, tagged, ans reased 50 bears. One year later, a randon sample of 100 bears included only 2 tagged bears. What is the conservationist's estimate of the size of bear population?
2)Telephone lens. formula 1/f = 1/o + 1/i
Find the image distance i for an object that is 2,000,000 mm from a 250-mm telephone lens.
Thanks

Real population/captured population = tagged population /captured-tagged pop.
Real pop/50 = 100/2
Real pop = 50(100/2) - 2500
---------------------------------
2)Telephone lens. formula 1/f = 1/o + 1/i
Find the image distance i for an object that is 2,000,000 mm from a 250-mm telephoto lens.
--------
1/i = [1/f-1/o]
1/i = (o-f)/fo
i = (f*o)/(o-f)
----------------------
Question: What are f and o in your formula?

Cheers,
