Question

A piece of string is hung from the points (-6,3) and (6,3) in the plane so that it hangs “down” (in the -y direction) to just touch the origin as it’s vertex. How high above the x axis is the string over x=2

Answer 1

Explanation:

eq. of line through (0,0) and (6,3)

`slope=(3-0)/(6-0) =(1)/(2) \\y-0=(1)/(2) (x-0)\\y=(1)/(2)x\\when~x=2\\y=(1)/(2)*2=1`
