Farmers wishing to avoid the use of purchased seeds areincreasingly concerned about inadvertently growing hybrid plants asa result of pollen drifting from nearby farms. Assuming that thesefarmers raise their own​ seeds, the fractional portion of theircrop that remains free of hybrid plants t years later can beapproximated by ​P(t)=(0.93)^ t.
​a) Using this​ model, predict the fractional portion of thecrop that will be free of hybrid plants 10 yr after a neighboringfarm begins to use purchased seeds.
​b) Find P' (10) and explain its meaning.
​c) When will half of the crop be hybrid​ plants?
