# The mean position and one extreme position of the two different waves represented by $x=35 \sin(5t)$ and $x=8+23 \sin(8t)$ respectively are:

$\begin{array}{1 1}(a)\;46,0,28,-22 \\(b)\;0,-35,8,-15 \\( c)\; 23,0,28,46 \\(d)\; 0,23,5,-18 \end{array}$

Solve in the linear of 3 of this set.
Hence b is the correct answer.
