Solve the following system of equations algebraically for all values of a, b , and c a+4b+6c=23
a+2b+c=2
6b+2c=a+14

6/ 11 = 0.545454 so your answer is55%

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.
