Answer with Step-by-step explanation:
Let the volume be represented by 'V'
Since it is given that Volume varies with height 'h' and square of the girth 'g' we can write
where 'k' is a constant of proportionality
Now it is given that volume is 288 cubic meters for h= 40 meters and g =1.5 meters we can write

Thus the volume of the timber as a relation is

Part b)
Volume of 50 trees with height 75 meters and girth 2 meters is

The axis of symmetry is the fold line that splits the parabola down the middle.
Now, since a parabola is symmetrical, every point, except the vertex, will have a mirror image of another point if we folded the parabola over the axis of symmetry.
So if we know the axis of symmetry is x = 3 and one of our points
has the coordinates (5, 0), the other point will have the coordinates (3, 0).
The axis of symmetry is always halfway between the x-intercepts.
X intercept: y = 0
y= -3/4x -4
0 = -3/4 x - 4
4= -3/4 x
4 • -4/3 = x
-5.3 = x
y intercept: x = 0
y = -3/4 x -4
y = -3/4 (0) -4
y = -4
the points are (-5.3, 0) and (0, -4)
Commutative property of addition:
a + b = b + a
If we have : 2 + 5 = 5 + 2
it is B ) commutative property of addition.
