Answer:

Step-by-step explanation:

$(2^7 \cdot 3^{-5}\cdot 9)^4$

Use the Power of a Product Property, where:

$(ab)^n=a^nb^n$

Therefore:

$(2^7 \cdot 3^{-5}\cdot 9)^4\\=(2^7)^4\cdot(3^{-5})^4\cdot(9)^4\\=2^{28}\cdot3^{-20}\cdot9^4$

Plzzz help plzzzzzzzzzzzzzz

Given:

The figure of two quadrilaterals.

In $ABCD,AB=18,BC=20,CD=22,AD=24$

In $EFGH,EF=27,FG=30,GH=34, EH=36$

To find:

Whether the figures are congruent, similar or neither.

Solution:

Ratio of corresponding sides are:

$\dfrac{AB}{EF}=\dfrac{18}{27}$

$\dfrac{AB}{EF}=\dfrac{2}{3}$

Similarly,

$\dfrac{BC}{FG}=\dfrac{20}{30}$

$\dfrac{BC}{FG}=\dfrac{2}{3}$

$\dfrac{CD}{GH}=\dfrac{22}{34}$

$\dfrac{CD}{GH}=\dfrac{11}{17}$

And,

$\dfrac{AD}{EH}=\dfrac{24}{36}$

$\dfrac{AD}{EH}=\dfrac{2}{3}$

Clearly, $\dfrac{AB}{EF}=\dfrac{BC}{FG}=\dfrac{AD}{EH}\neq \dfrac{CD}{GH}$ .

All corresponding sides are not proportional.

Therefore, the figures are neither similar nor congruent. Hence, third option is correct.

Answer:the map notation is (x,y) to (y,-x) at a 90 degree angle

180 degrees map notation is (x,y) to (-x,-y)

360 degrees map notation is (x,y) to (-y,x)

Step-by-step explanation: the answer is they are congruent

In a board game, the player who makes the last move receives a 12-point bonus for ending the game.

Reika [66]

Answer:

f(s) = 2( 5s + 6)

Step-by-step explanation:

This means value of f of s

final score before bonus = 2 x 5 = 10

Add the bonus = 2 x 6 = 12

Add together if simplified= 10s+12, we remove the s, then add and confirm score has now been fully totaled = 22.

Half way through we can show 10s is the score of both even and only fs = 22 for the winner.
