Juan makes a map of his neighborhood for a presentation. The scale of his map is 1 inch: 125 feet. During a practice run of his presentation in front of his family, Juan realizes that his map is far too small. He decides to make his map 5 times as large. What would be the scale of the larger map?

The correct answer is .44

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.

  d: 0.7(t + 4 + 2) = t .
