In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .
Answer:
Faces = 6
Vertices = 8
Edges = 12
Step-by-step explanation:
In a solid geometric shape :
A face is a flat surface : faces = 6
A vertex (plural: vertices) is a Corner : vertices = 8
An edge is a particular type of line segment joining
two vertices : Edges = 12
Answer:
You will need 400 meters of cord.
Step-by-step explanation:
Since it's a square, we know the perimeter of the piece of land is 20 times 4, or 80. Because it is going around it 5 times, we just multiply 80 by 5 to get 400. You will need 400 meters of cord.
A=(3.14)r^2
A=(3.14)3^2
A=(3.14)9
A=28.26ft^2
Hope it helps and is correct :)
