Application. the sine function. 9. The following graph shows the velocity of a person's breath while at rest. Express the graph in terms of (2 marks) 10. The depth of the ocean at a swim buoy can be modelled by d(t) = 2sin -1 \+4, where d is the depth of the water (in meters) and t is the time (in hours), where OSt S24, and : = 0 represents midnight. Sketch the graph of d(t) in the grid provided, and determine when the depth of the [4 marks] water is 3 m. Show all the required calculations for full marks. -NW AUD VO 8 10 12 14 16 1
