What is the number 2,141 estimated to the nearest thousand

The answer is 2,000 if I'm not mistaken

It would be 2000 because 141 is closer to 0 so yah

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b

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.
