Answer:

Step-by-step explanation:
we know that
If the base of the solid is a circle and all plane sections perpendicular to a fixed diameter of the base are equilateral triangles
then
The solid is a cone
The volume of a cone is equal to

we have

Find out the height of the cone
Remember that
If all plane sections perpendicular to a fixed diameter of the base are equilateral triangles
then
The length side of each equilateral triangle is equal to the diameter of the base
Applying the Pythagoras Theorem find out the height of the cone

we have
----> the diameter is two times the radius

substitute and solve for h




Find the volume


assume


After solving, you response should be "122", remember PEMDAS, always do parentheses!
Answer:
- The point (x, y) → (-5, 0) is the vertex of the graph.
Step-by-step explanation:
As the given graph represents Parabola
- As we know that Parabolas always contain the lowest point, or the highest point if any given parabola is upside-down. This lowest or highest point is the location where the parabola tends to change its direction and called the 'vertex'.
Hence, from the given graph, we can easily determine that the parabola changes its direction at x = -5, and y = 0.
- Therefore, the point (x, y) → (-5, 0) is the vertex of the graph.
