A water tank holds 468 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 624 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same? The amount of water in the two tanks will be the samein
weeks.

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.
