Bob has 8754 tim has 4839 the value of 8 in bob number is how many times greater than the 8 in tim number

To compare between the numbers take the nber as a percentage or a fraction:
(8/8754)*100=0.091%
(8/4839)*100=0.165%
0.165 is greater than 0.091 so the value of 8 in Tim number is greater.

In an easier way the greater the donominator the lower the value of that number. Hence 8/8754 is less than 8/4839

3915 is the answer cause if you subtract the numbers but greater to least so you get 3915

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.
