What is: 13 to the 3rd power 2/5 to the second power and 0.9 to the second power

1. 13*13*13 =2197
2. 2/5*2/5 = 4/25
3. 0.9*0.9 = 0.81

13 to the 3rd power is 2197
2/5 to the second power is 4/25
and 0.9 to the second power is 0.81

Hope i can you!

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.
