what are the 3 r's when it comes to treestand safety?

The 3 R in treestand safety is stands for rescue, relief and recover.

Step-by-step explanation:

The 3 R in treestand safety is stands for rescue, relief and recover.

Treesstand safety include following guidelines

1) Do use safety belt to replace a chain; do not use a rope.

2) Read the instructions on the correct use and modification of the belt system extensively.

3) If you wear a harness device, do not leave the ground.

4) Safe belt tied to tree position to avoid you from dropping.

5) Before hunting from it, test your tree stand each year; remove worn parts.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
