in the diagram, AE is tangent to the circle at point a and secant DE intersects the circle at point C and D. the iines intersect
AlexFokin [52]
Recall the secant-tangent theorem, and you have
EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10

I suspect a typo somewhere in the murk above

Simplify the radical expression.. square root of 128
Vaselesa [24]
Hello,

first we have to descompose the number:

128  | 2
  64  | 2
  32  | 2
  16  | 2
    8  | 2
    4  | 2
    2  | 2
    1

So: 
128= 2x2x2x2x2x2x2 \\ 128=2^{6} *2

Therefore:
\sqrt{128}= \sqrt{2^{6} *2}

You must know these properties:

\sqrt{a*b} = \sqrt{a} * \sqrt{b}\\ \\ \sqrt[b]{x^a}= x^{ \frac{a}{b}}

then:

\sqrt{2^{6} *2} \\ =\sqrt{2^{6}}*\sqrt{2} \\ =2^{ \frac{6}{2}}*\sqrt{2} \\ =2^3*\sqrt{2} \\ \boxed{=8*\sqrt{2}}

What is the reciprocal of two ninths
LenaWriter [7]
<h2>Answer: 9/2</h2>

Step-by-step explanation:

<em>The answer is 9/2 because reciprocal means you just flip the fraction that you are solving. So, the opposite  of 2/9 is 9/2 AKA, if you flip 2/9, it would be 9/2.</em>

Where will her cut be located? Round to the nearest tenth. x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1 A
Arte-miy333 [17]

Answer:

The correct answer is 25.2 in.

Step-by-step explanation:

It is given that number line goes from 0 to 60 which can be used to represent a ribbon of length = 60 inches.

2 inches of the ribbon are frayed so actual length = 58 inches

Please refer to the attached image for the ribbon.

A is at 0

C is at 60

B is at 2

P is the point to divide the remaining ribbon in the ratio 2:3.

Part AB of the ribbon is frayed.

BP: PC = 2:3

Let BP = 2x and PC = 3x

Now, BP + PC = BC = 58 = 2x + 3x = 5x

So,

5x =58\\\Rightarrow x =11.6

BP = 2\times x = 2 \times 11.6 = 23.2\ inches

Location of the Cut = 2 + 23.2 = <em>25.2 inches</em>

<em></em>

Alternatively, we can use the formula directly:

x = \dfrac{m} {m + n } (x_2 - x_1) + x_1

x_1 = 2\\x_2 = 60

m: n is the ratio 2:3

x = \dfrac{2} {2 +3 } (60- 2) + 2\\\Rightarrow 0.4 (58 )+2\\\Rightarrow 23.2+2 \\\Rightarrow \bold{25.2\ inches}
