What is the smallest degree of rotation that will map a regular 18 gon on to itself

natali 33 [55]

Answer:

20°

Step-by-step explanation:

Rotating the figure through an angle equal to the central angle of one "sector" will do the required mapping. That is 360°/18 = 20°.

The volume of a cylinder is given by the formula <img src="https://tex.z-dn.net/?f=V%2B%20%5Cpi%20r%5E2h" id="TexFormula1" title

n200080 [17]

V = $\pi r^{2}h$ where r is radius and h is height

so when radius is (x+8) and height is (2x+3),

volume = $\pi (x+8)^{2}(2x+3)$

Find the coordinates of the midpoint of a segment with the endpoints (16,5) & (28,-13)

frutty [35]

$\text{The formula of the midpoint of a segment with the end points:}\\\\A(x_A;\ y_A)\ \text{and}\ B(x_B;\ y_B)\\\\M_{AB}=\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

$\text{We have:}\\A(16;\ 5)\to x_A=16;\ y_A=5\\B(28;\ -13)\to x_B=28;\ y_B=-13\\\\\text{substitute:}\\\\M_{AB}=\left(\dfrac{16+28}{2};\ \dfrac{5+(-13)}{2}\right)=\left(\dfrac{44}{2};\ \dfrac{-8}{2}\right)=(22;\ -4)$

Locate the point in the complex plane and express the number in polar form.

EleoNora [17]

Answer:

We kindly invite you to see the result in the image attached below.

The number in polar form is $z = 3\sqrt{5}\cdot e^{i\cdot 0.352\pi}$ .

Step-by-step explanation:

A complex number is represented by elements of the form $a + i\,b$ , for all $a$ , $b$ $\in \mathbb{R}$ . The first part of the sum is the real component of the complex number, whereas the second part of the sum is the imaginary component of the complex number. The real component is located on the horizontal axis and the imaginary component on the vertical axis.
