Bernard's bird feeder holds 4 1/2 cups of birdseed. Bernard is filling the bird feeder with a scoop that holds 9/10 of a cup. How many scoops of birdseed will Bernard put into the feeder? Write your answer as a fraction or as a whole or mixed number.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
