Answer:

AC = 10

Step-by-step explanation:

We can apply the properties of two secants intersecting outside a circle

(see attached for reference).

in our case, our formula will be

BC (BC + AB) = CD (CD + DE), which can be written as:

BC · AC = CD · CE

We are given:

BC = 6, DC = CD = 5, CE = 12

simply substitute the known values into the equation above

6 · AC = 5 · 12

AC = (5)(12) / 6

AC = 10

Answer:

Step-by-step explanation:

(Note that the diagram is not to scale)

You know BC is 6

You know DC is 5

You know CE is 12

Using K's position, it shows that AC is one off from EC

AC=11

Graph the inequality x>-8 using the steps

Yuki888 [10]

Hey!

Your point on the graph would be ( -8, 0 ).

We shade the right side of the graph because the inequality shows that x is greater than -8.

Hope this helps!

How to convert nonlinear equation to linear equation?

9966 [12]

Let's take the non-linear equation:
${x}^{2} = \sqrt{3} y$
First Make The Equation To Be In Terms of Y

*Divide Both sides by
$\sqrt{3}$
$\frac{ {x}^{2} }{ \sqrt{3} } = \frac{ \sqrt{3} y}{ \sqrt{3} }$
*Simplify
$\frac{ {x}^{2} }{ \sqrt{3} } = y$
You shouldn't keep a radical in the denominator, however we leave it for the purpose of the reciprocal.

*Take The Reciprocal Of Both Sides
$\frac{ \sqrt{3} }{ {x}^{2} } = \frac{1}{y}$
A Linear Equation Takes The Format:
$y = mx + b$
So,
$\frac{1}{y} = y$
$b = 0$
$m(slope) = \frac{ \sqrt{3} }{x}$
$x = \frac{1}{x}$
Resulting in :
$\frac{1}{y} = \frac{ \sqrt{3} }{x} (\frac{1}{x} ) + 0$

How do you solve for the central area of a polygon?

ycow [4]

Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.

Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
