The revenue from ring tones was $90 million in 2003 and has grown by about 110% per year since then. That is, each year the revenue is about 2.10 times the previous year's revenue. Let r=h(t) be the revenue (in millions of dollars) from ring tones in the year that is t years since 2003. A) find an equation of h h(t)=? B)What is the r intercept of the model?What does it mean in this situation? C)What is base b of h(t)=ab^t What does it mean in this situation? D) Predict the revenue from ring tones in 2009
