Nigel and mia are searching for a treasure chest under
water. the straight line distance between them is 100
meters
given the angles in the diagram, who is closer to the
treasure chest and why?
nigel
mia
100 m
65°
80°
nigel is closer because his distance to the chest is
opposite the larger angle.
mia is closer because her distance to the chest is
opposite the smaller angle
nigel is closer because his distance from the chest is
100 meters.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
