i'm guessing that twice differentiable means y''
i really don't know how to start this problem
sorry about that: when t=0, r't=5.7; t=2, r't=4; t=5, r't=2; t=7, r't=1.2; t=11, r't=.6; t=12, r't=.5
t: 0 2 5 7 11 12 r'(t): 5.7 4.0 2.0 1.2 0.6 0.5 The volume of a spherical hot air balloon expands as the air inside the balloon is heated. The radius of the balloon in feet is modeled by a twice-differentiable function of r of time t, where t is measured in minutes. For 0&...

The upward velocity of the water in the stream of a particular fountain is given by the formula v = -32t + 28, where t is the number of secondds after the water leaves the fountain. While going upward, the water slows down until, at the top of the stream, the water has a veloc...
