Analyze the reflectional symmetry of the regular polygons. The square has -fold reflectional symmetry. The regular octagon has -
postnew [5]

Answer:

The square has 4-fold reflectional symmetry. The regular octagon has 8-fold symmetry.

Step-by-step explanation:

For a square,

There are two lines of symmetry along two diagonals and

two lines of symmetry along midpoints of two pairs of opposite sides.

Therefore, there are 4 lines of reflectional symmetry in total.

For a regular octagon,

There are four lines of symmetry along four diagonals and

four lines of symmetry along midpoints of four pairs of opposite sides.

Therefore, there are 8 lines of reflectional symmetry in total.

Anyone? Know how to do this?
ki77a [65]

Answer:

  • x = 4
  • length = 19 ft
  • width = 11 ft

Step-by-step explanation:

The area is given by the product of length and width.

  A = LW

  209 = (4x +3)(4x -5)

  209 = 16x^2 -8x -15

  224 = 16x^2 -8x

You could rearrange and use the quadratic formula at this point, but we elect to "complete the square".

  14 = x^2 -(1/2)x

  14 +1/16 = x^2 -1/2x +(1/4)^2 . . . . . add the square of half the x-coefficient

  (x -0.25)^2 = 14.0625

  x = 0.25 ± 3.75 . . . . . . take the square root; add 0.25

Only positive values of x are useful here, so we have

  x = 4

Then the dimensions are ...

  length = 4x +3 = 4(4) +3 = 19 . . . feet

  width = 4x -5 = 16 -5 = 11 . . . feet

A parabola has a vertex at (-3,2). Where is the axis of symmetry?
vladimir1956 [14]

Answer:

x=-3

Step-by-step explanation:

If a parabola has a vertex at (h,k), the axis of symmetry is at the point, x=h.

That is, <u>the x-coordinate of the vertex of the given parabola is the axis of symmetry.</u>

Therefore, for a parabola with vertex (-3,2), the axis of symmetry is at x=-3
