Sketch the points (0,5,2),(4,0,-1),(2,4,6) and(1,-1,2) o a single set of coordinate axes?
nordsb [41]
Explanation:
As points have three coordinates i.e. x, y and z hence the sketch of the given four points is drawn in 3D shape and for that picture is attached here with this answer.
Points are given in the format as below
(value of x-coordinate , value of y-coordinate , value of z-coordinate)
In the attachment:
Point A = (0,5,2) (in blue color)
Point B = (4,0,-1) (in purple color)
Point C = (2,4,6) (in orange color)
Point D = (1,-1,2) (in black color)
The answer is 7 h...Hope it works :)

Answer:
fenced off land
agriculture
introduction of sheep and cattle
excessive hunting
Explanation:
These are all factors that the pioneers introduced to the prairies and which forever changed the natural environment of the region. The pioneers brought with them sheep and cattle, as they considered these necessities to sustain their way of life. However, these were new introductions to the area and required the land to be fenced in order to keep them from leaving. To sustain themselves, they also relied on agriculture and hunting. Agriculture changed the ecosystem of the area, as well as its appearance. Hunting was eventually done to an excessive degree, leading to the decline of many species, such as the American bison.
