To find the total length of the two copper pipes, we need to add them together.
2 5/12 + 3 7/12 = 5 12/12
Since 12/12 = 1 or a whole, we can simplify this further.
5 12/12 = 6
Hope this helps!
The equation is given as

<h3>The Amplitude </h3>
The Amplitude can be calculated as

<h3>The Vertical Shift</h3>
The vertical shift is the average difference between the maximum and minimum.

For b value
The Time Period will be twice the distance between max and min.

<h3>The Period</h3>
The period is calculated as

The equation is given as

9x + 1 + 7x - 9 = 5x - 11
16x - 8 = 5x - 11
11x - 8 = -11
11x = -3
-3/11 = x
11%= 0.11 and 8%= 0.08
0.11 x 67,530=7,428.3
0.08 x 85,740 = 6,859.2
so person A made more than person b
F-1(x) = x\5 + 6/5
