Chapter 5.5, Problem 24E

how would I find velocity(t) and acceleration(t) using this data and equation?

-2Fonslowcountyscho The average value of gold per ounce over time is modeled by V(†) = 45†+ 279, where t = time in years since 2000. According to this function, how many years will it take for the gold to be worth $639?

The equation n = 0.03t² 0.58t + 3.98, models, n, the number (in millions) of people who moved to another state in the year that is t years since 1990. The table below shows some of the data that were used to find this model. Year 1995 1998 2001 2004 2006 Number of People Who Moved to Another State (millions) a. When t = 1.8 1.2 1.1 1.5 2.1 0 what is the value of n? What does it mean in this situation? Select an answer b. Estimate the number of people who moved to another state in 2005. million (Round to the nearest tenth of a million.) c. Predict the number of people who moved to another state in 2014. million (Round to the nearest tenth of a million.)
