Answer:

see explanation

Step-by-step explanation:

Given

x² - 6x + 7 = - 13

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + (- 3)² + 7 = - 13 + (- 3)²

x² - 6x + 9 + 7 = - 13 + 9

(x - 3)² + 7 = - 4

babymother [125]

Answer:

  a) 150°

  b) 30°

Step-by-step explanation:

It is easier to work the exterior angle first.

<h3>b)</h3>

The sum of exterior angles is 360°. The exterior angle at any vertex of a regular dodecagon will be 1/12 that:

  360°/12 = 30° . . . the measure of one exterior angle

__

<h3>a)</h3>

The measure of an interior angle will be the supplement of the adjacent exterior angle.

  180° -30° = 150° . . . the measure of one interior angle

Work out the circumference of this circle.
DIA [1.3K]

The circumference of a circle will be 131.964.

What is circumference of a circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.

The radius of the circle given is = 21cm

circumference is 2πr = 2*3.142*21 = 131.964cm.

Hence the circumference of a circle 131.964cm.

Find the point slope equation for the line that passes through the points (1,-9) and (-10,101)
neonofarm [45]

Answer:

( y + 9 ) = -10( x - 1 )

Step-by-step explanation:

First we calculate the slope

m=\frac{-9-101}{1-(-10)} =-10

Then we choose a point it could be (1,-9) or (-10,101), I choose (1,-9), the slope point form is (y-y1)=m(x-x1)

( y - (-9) ) = -10( x - 1 )

( y + 9 ) = -10( x - 1 )

it could be also...

( y - 101  )= -10( x- (-10) )

( y - 101 ) = -10( x + 10 )
