Solve.In 1996, an outbreak of a disease infected 17 people in a large community. By 1997, the number of those infected had grown to 29. Find an exponential growth function that fits the data. (Round decimals to three places.)
A. N(t) = 17e0.534t, where t is the number of years after 1997. B. N(t) = 17e5.34t, where t is the number of years after 1996. C. N(t) = 17e0.534t, where t is the number of years after 1996. D. N(t) = 17e5.34t, where t is the number of years after 1997.
Solve the initial value problem.
= e2t + 8 sin t, y(0) = 0, y'(0) = 5
A. y = 
- 8 sin t
B. y =

C. y = e2t - 8 sin t + 12t - 
D. y = 
- 8 sin t + 
t -
