You travel 9 3/8 miles from your house to a shopping mall. you travel 2/3 of
that distance on an interstate. the only road construction you encounter
is on the first 2/5 of the interstate. on how many miles of your trip do you
encounter construction?

Cis your correct answer

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.
