1. Describe a banjo, it's appearance, its construction, its sound, and how it is used musically.

A banjo has 4 or 5 strings. Most commonly it is tuned in a G chord, although it is also tuned in other chords. The body is made with the same material as the top of a drum with a kind of metalic sound. Banjos are commonly played in bluegrass music.

true

that is the way that they talked back then

=)

coordinates of r(b,c)

slope of nm is 0.

step-by-step explanation:

the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

the midpoint of the line segment nk is given by

∴r(b,c)

the slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

slope of rs is

hence

coordinates of r(b,c)

and slope of nm is 0.
