Find the slope as a decimal number of the line that passes through the points (21,10) and (-19,0)?

1/4

Step-by-step explanation:

We can find the slope given two points by using

m = (y2-y1)/(x2-x1)

    = (0-10)/(-19-21)

    = -10/(-40)

   = 10/40

    = 1/4

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
