Which is the next step in the following construction of a regular hexagon?
mezya [45]

With compass setting the same as PA. place the compass at P and draw an arc above the diameter.

<h3>What is a Hexagon?</h3>

This is a polygon which has a total number of six sides and internal angle which is 720 degrees.

The compass should be placed at P and an arc above the diameter after which they are joined to form a hexagon.

Select the expression that simplifies to 1 / x^1/8
Troyanec [42]

Answer:

\left(\displaystyle \sqrt[3]{x^{-\tfrac 35}}\right)^{\tfrac 58}

Step-by-step explanation:

\left(\displaystyle \sqrt[3]{x^{-\tfrac 35}}\right)^{\tfrac 58}\\\\\\=\left[ \left(\displaystyle x^{-\tfrac 35} \right)^{\tfrac 13 \right]^{\tfrac 58}\\\\\\=\left( \displaystyle x^{-\tfrac 35}\right)^{\tfrac 5{24}}\\\\\\=x^{ \displaystyle -\tfrac{3}{24}  \right}\\\\\\=x^{\displaystyle -\tfrac 18  }\\\\\\=\dfrac 1{x^{\tfrac 18}}

Find an equation of the line. Write the equation using function notation.
Gemiola [76]

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

y = -4x+9

Step-by-step explanation:

Given equation of line is:

4y=x-8

We have to convert the given line in slope-intercept form to find the slope of the line

So,

Dividing both sides by 4

\frac{4y}{4} =\frac{x-8}{4}\\y = \frac{1}{4}x-\frac{8}{4}\\y = \frac{1}{4}x-2

Let m1 be the slope of given line

Then

m_1 = \frac{1}{4}\\

Let m2 be the slope of line perpendicular to given line

As we know that produt of slopes of two perpendicular lines is -1

m_1.m_2 = -1\\\frac{1}{4} . m_2 = -1\\m_2 = -1*4\\m_2 = -4

The slope intercept form of line is given by:

y = m_2x+b

Putting the value of slope

y = -4x+b

to find the value of b, putting (3,-3) in equation

-3 = (-4)(3) + b\\-3 = -12 +b\\b = -3+12\\b = 9

Putting the value of b in the equation

y = -4x+9

Hence,

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

y = -4x+9
