I have 17 coins worth of $2.05. The coins include quarters, dimes, and nickels. There are twice as many nickels as dimes. How many of each type of coin do I have?

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4

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.
