3. a person of mass 3m is standing on the left edge of a long, uniform board of mass m and length l
that is floating in water, as shown in the figure below. the person walks slowly to the right edge of
the board. the water exerts no drag forces on the board. find the position of the center of mass of
the board when the person is at the right edge of the board,

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
