NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h(t) - 4.9t? + 103t + 325. %3D Assuming that the rocket will splash down into the ocean, at what time does splashdown occur? The rocket splashes down after seconds. How high above sea-level does the rocket get at its peak? The rocket peaks at meters above sea-level. Question Help: DVideo 1 DVideo 2

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.)
