Answer:

  • ≈ 44.0°

Step-by-step explanation:

Use trigonometry

<u>The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine:</u>

  • cos x = 18/25 = 0.72
  • cos x = 0.72
  • x = arccos 0.72
  • x = 43.9455° ≈ 44.0° rounded

Is the Mandelbrot set locally connected?
MariettaO [177]

Answer:

Step-by-step explanation:

It is conjectured that the Mandelbrot set is locally connected. This famous conjecture is known as MLC (for Mandelbrot locally connected). By the work of Adrien Douady and John H. Hubbard, this conjecture would result in a simple abstract "pinched disk" model of the Mandelbrot set. In particular, it would imply the important hyperbolicity conjecture mentioned above.

The work of Jean-Christophe Yoccoz established local connectivity of the Mandelbrot set at all finitely renormalizable parameters; that is, roughly speaking those contained only in finitely many small Mandelbrot copies.[19] Since then, local connectivity has been proved at many other points of {\displaystyle M}M, but the full conjecture is still open.

What is the greatest perfect square of 1290
Alex73 [517]
<span>It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!</span>
