Round 5.64 to the nearest 10th show how you got the answer

Hey there Teleshiagraham,
The number after each decimal point goes with the name called tenths, hundredths and so on..
Thus, 5.64 (6 is in the tenths place and 4 is in the hundredth place and it is below 5, so your round down)
Thus the answer is 5.6

Hope this helps :))

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.
