What fractional part is polygons?
a lml told me to vertex it
A base angle of an isosceles triangle is 9 degrees more than the vertex angle Find the vertex angle?
let the vertex angle be x degrees, then the base angle is x + 9 degrees. Since in a triangle the sum of the angle is 180 degrees, and the base angles in an isosceles triangle are congruent, we have: x + 2(x + 9) = 180 x + 2x + 18 = 180 3x + 18 = 180 subtract 18 to both sides 3x = 162 divide by 3 to both sides x = 54 Thus the vertex angle is 54 degrees.
What shape has 15 edges and 9 vertex?
Not sure there is such a shape. In order to satisfy the Euler characteristics, the shape must have 8 faces and so is an octahedron. But there seems to be no octahedron with 9 vertices.
What is the axis of symmetry for 9 sided shapes?
A nine sided 2-D shape (a nonagon) need not have any symmetry. It can have 1, 3 or 9 axes of symmetry: in each case from a vertex to the middle of the opposite side.
How many vertices does an octagonal pyramid have?
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
Solution of deriving vertex from the quadratic function?
2 AND 9
Which statement describes the rate of change of the following function?
Which statement describes the rate of change of the following function?f(x) = -6x - 9
What is the vertex of x2 plus 18x plus 19?
The vertex is (-9, -62).
What is the trinomial of x2 plus 8x-9?
x2 + 8x - 9 is a quadratic expression that describes a parabolic function. It can be factored out as: (x + 9)(x - 1) Which tells us that if we graphed it as a function of x, it would intersect the x-axis at the points (-9, 0) and (1, 0). It's derivative is: 2x + 8 which tells us that it's vertex is at the x-location -4, at the point (-4, -25). The second derivative is 2, which tells us that the vertex is a minimum, and that the function's range is: {f(x) | f(x) ≥ -25, f(x) ∈ ℜ}
How many diagonals does a hexagon have?
A hexagon has 9 diagonals. Each vertex of a n-sided polygon can be connected to n - 3 others with diagonals. Thus n(n - 3) possible diagonals. However, when Vertex A is connected to vertex C, vertex C is also connected to vertex A, thus each diagonal is counted twice. Thus: number_of_diagonals = n(n - 3)/2 = 6(6-3)/2 = 6x3/2 = 9
How many vertex does a rhomboid have?
9 or 6 depending on what kind of mood its in
What 3d shape has 6 vertex and 9 edges?
A triangular prism.
How many diagonals can be drawn from one vertex of dodecagon?
12-3 = 9
The vertex of this parabola is at 3 -2 When the x value is 4 the y value is 3 What is the coefficient of the squared expression in the parabolas equation?
Vertex = (3, - 2)Put in vertex form.(X - 3)2 + 2X2 - 6X + 9 + 2 = 0X2 - 6X + 11 = 0=============The coefficeint of the squared term is 1. My TI-84 confirms the (4, 3) intercept of the parabola and the 11 Y intercept shown by the function.
What are the coordinates of the vertex of y x2 - 4x - 5?
