Solve.A painting was sold in 1985 for $ 1 million. The painting was then resold in 1996 for $ 10 million. Assume that the painting's value increases exponentially. Find the exponential growth rate k, and determine the exponential growth function, assuming V0 = 1. (Round decimals to three places.)
A. k = 0.209; V(t) = 1e0.209, where V(t) is in millions and t is the number of years after 1985. B. k = 0.192; V(t) = 1e0.192t, where V(t) is in millions and t is the number of years after 1985. C. k = 0.209; V(t) = 1e0.209t, where V(t) is in millions and t is the number of years after 1985. D. k = 0.209; V(t) = 1e0.209t, where V(t) is in millions and t is the number of years after 1997.
