What is the annual growth rate of the paintings value? Write the answer as a percentage rounded to the nearest tenth

 

The function V=250(1.28)^d models the value of a rare painting, in thousands of dollars, d decades after is is sold at an auction for $250,000. What exponential function modelss the value of painting after t years?                                                                                                                                                                   

 V=250(?)^t

\(a^t = e^{\ln(a)t}\)

V =250 (10^(t/93.27) )

 

or

 

 

V = 250 (1.02499^t)

\(\text{Ok, my response didn't really apply. I misunderstood what they wanted}\\ V = 250(1.28)^d\\ V = 250(1.28)^{\frac {t}{10}}\\ V = 250\left((1.28)^{\frac{1}{10}}\right)^t\\ V = 250(1.025)^t\)
