In 2004, an art collector paid $93,639,000 for a particular painting. The same painting sold for $30,000 in 1950. Complete parts (a) through (d). a) Find the exponential growth rate k, to three decimal places, and determine the exponential growth function V, for which V(t) is the painting's value, in dollars, t years after 1950. V(t) = (Type an expression. Type integers or decimals for any numbers in the expression. Round to three decimal places as needed.)
