C: 3 Bottles
D: 4 Bottles
B. It is a circle.
C. It must be a square.
D. It is a triangle.
Answer:
A. It can be any polygon.
Step-by-step explanation:
A pyramid is a polyhedron with a base, which can be any polygon, but is most often a square.
When the base is a triangle, the pyramid has a total of four faces.
The famous Egyptian pyramids have square bases and four triangular faces. As the number of sides increases in a pyramid, it begins to look like a cone.
So, we can say A and C are both correct. But we will go with A as a square will also be considered in it.
x = 3
y = 4
y = 3
What's the center?
Answer:
To reflect a point across the vertical line x = -2, we can use the formula:
(x, y) → (2c - x, y)
where c is the x-coordinate of the line of reflection. In this case, c = -2. Let's apply this formula to the point W(-4, -4):
W' = (2(-2) - (-4), -4)
= (-4 + 4, -4)
= (0, -4)
Therefore, after the reflection across x = -2, the coordinates of W(-4, -4) become W'(0, -4).
