If the polygons are similar, the corresponding sides are proportional.

corresponding sides:

AE - BD

AB - ED

BC - DC

AC - EC

You have proportions:

$\dfrac{AE}{BD}=\dfrac{AC}{BC}=\dfrac{EC}{DC}\\\\\dfrac{AB}{ED}=\dfrac{BC}{DC}=\dfrac{AC}{EC}$

and their modifications

How many solutions are there to the equation below?

Effectus [21]

Answer:

C. 1

Step-by-step explanation:

Given:

$\displaystyle \large{\sqrt{\sqrt{\sqrt{x}}} = 16}$

The equation can be rewritten as:

$\displaystyle \large{\sqrt[8]{x} = 16}$ via surd property.

Since it’s an even surd, that means there only exists zero-positive numbers for value of x.

To solve this surd equation, simply clear out the surd by powering both sides by 8:

$\displaystyle \large{\left(\sqrt[8]{x}\right )^8=(16)^8}$

Cancel the surd:

$\displaystyle \large{x=16^8}$

Now, evaluating 16^8 will give up a million and that’s not necessary because we are finding how many solutions this equation has. Since theee only exists one value of x, which is the solution to this equation. Therefore:

Your answer is 1 solution

Write the equation in slope - intercept form of the line that

galina1969 [7]

y1 - y2 / x1 - x2

4 - 2 / 2 - 2

2/0

y = mx + b

2 = 0(2) + b

2 = b

y = 0x + 2

y = 2

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A = {1, 3, 5, 7, 9}, B = {2, 4, 6, 8, 10}, and C = {1, 2, 4, 5, 8, 9}. List the element

Leto [7]

Answer:

$C\ n\ C^c = \{ \}$

$(A\ n\ C)^c = \{2,3,4,6,7,8,10\}$

$A\ u\ (B\ n\ C) = \{1, 2,3, 4,5, 7, 8,9\}$

Step-by-step explanation:

Required

Determine

$C\ n\ C^c$

$(A\ n\ C)^c$

$A\ u\ (B\ n\ C)$

Solving $C\ n\ C^c$

$C^c$ implies that elements in U but not in C

Since

$C = \{1, 2, 4, 5, 8, 9\}$

$C^c = \{3, 6, 7, 10\}$

$C\ n\ C^c = \{1, 2, 4, 5, 8, 9\}\ n\ \{3, 6, 7, 10\}$

$C\ n\ C^c = \{ \}$

<em>Because there's no intersection between both</em>

Solving $(A\ n\ C)^c$

First, we need to determine A n C

$A\ n\ C = \{1, 3, 5, 7, 9\}\ n\ \{1, 2, 4, 5, 8, 9\}$

$A\ n\ C = \{1, 5, 9\}$

$(A\ n\ C)^c = (\{1, 5, 9\})^c$

$(A\ n\ C)^c = \{2,3,4,6,7,8,10\}$

Solving $A\ u\ (B\ n\ C)$

First, we need to determine B n C

$B\ n\ C = \{2, 4, 6, 8, 10\}\ n\ \{1, 2, 4, 5, 8, 9\}$

$B\ n\ C = \{2, 4, 8\}$

So:

$A\ u\ (B\ n\ C) = \{1, 3, 5, 7, 9\}\ u\ \{2,4,8\}$

$A\ u\ (B\ n\ C) = \{1, 2,3, 4,5, 7, 8,9\}$
