Assume we started tracking the data in 2000 when the number of sunspots was at a maximum. Write a cosine function nit) which models this phenomenon in terms of the time t which represents the years since 2000.

At t = 3s, he is at one end of his swing and 4m from the window. Att = 7s, he is at the other end of his swing and 20m from the window. Write an equation to model this situation. Oy = -8 sin = (x - 3) + 12 Oy = -10 cos " (x - 3) + 12 O y = 8 cos #(x + 3) - 12 O y = 10 cos # (x + 3) - 12 Question 10 10 pts A few students finished up their NCVPS work early and are playing skip rope. As the ope rotates it is observed that its maximum height is 2.75m after 1 second. The first minimum height of 0.25m occurs 2 seconds after the maximum height. Sketch a graph to model the situation.
