Sunspot Activity The activity of the Sun (sunspots, solar flares, and coronal mass ejection) fluctuates in cycles of around 10–11 years. Sunspot activity can be modeled by the following function:
where t is the number of years since January 1, 1997, and
a. What is the period of sunspot activity according to this model? (Round your answer to the nearest 0.1 years.)
b. What is the maximum number of sunspots observed? What is the minimum number? (Round your answers to the nearest sunspot.)
c. When, to the nearest year, was sunspot activity expected to reach the first high point beyond 2012?

- The position of a particle that moves along the x-axis is defined by x = - 3t^2 + 12^t - 6 f, where t is in seconds. For the time interval t = 0 to t = 3 s, (1) plot the position, velocity, and acceleration as functions of time; (2) calculate the distance traveled; and (3) determine the displacement of the particleshow the graph and write the solution with a penarrow_forwardThe position of a particle that moves along the x-axis is defined by x = - 3t^2 + 12^t - 6 f, where t is in seconds.
