A basketball player is 6ft 8 inches tall. A model of a basketball player is 5 inches tall. What is the scale factor?

So I get that you have to convert everything to inches but I don't get the nest step???

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
