Rotating 270 degrees counterclockwise about the origin is the same as rotating 90 degrees clockwise about the origin, which can be expressed in coordinate notation $(x,y) \longrightarrow (y, -x)$ .

So, the vertices of the image are:

$U(4,0) \longrightarrow U'(0, -4)\\\\T(5,0) \longrightarrow T'(0, -5)\\\\S(5,-1) \longrightarrow S'(-1, -5)\\\\R(4, -1) \longrightarrow R'(-1, -4)$

What is the distance between point W and X to nearest hundredth?

quester [9]

Answer: 16.97

<u>Step-by-step explanation:</u>

To find the distance from W to X, you can use the distance formula ...or... draw a right triangle using W and X as the vertices and use Pythagorean Theorem to find the hypotenuse. I will solve using the latter.

The y-distance from W to X is 12.

The x-distance from W to X is 12.

hypotenuse² = 12² + 12²

= 144 + 144

= 288

hypotenuse = $\sqrt{288}$

= 16.97

1) What is 20% of 20?<br> 2) what is 15 is what percent of 30?<br> 3) 50 is 50% of what?

N76 [4]

Hi there!

The word "of" is the same thing as a multiplication sign.

20% = 0.2

0.2 × 20 = 4

? × 30 = 15

divide each side of the equation by 30

? = 0.5

0.5 = 50%

50% = 0.5

0.5 × ? = 50

divide each side of the equation by 0.5

? = 100

There you go! I really hope this helped, if there's anything just let me know! :)

The expression that represents the number of days until only 10% remains is

T((d) 10%) = 100 • (1/2)^3.322

Cuanto es la respuesta de -126=14k?

N76 [4]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \text{k = - 9}}}}}$

Step-by-step explanation:

$\star{ \text{ - 126 = 14k}}$

$\text{step \: 1 \: : Intercambia los lados de la ecuación}$

$\hookrightarrow{ \sf{14k = - 126}}$

$\text{step \: 2 : Divide ambos lados por 14}$

$\hookrightarrow{ \sf{ \frac{14k}{14} = \frac{ - 126}{14}}}$

$\text{step \: 3 \: : Calcular}$

$\hookrightarrow{ \sf{k = - 9}}$

$\text{el valor de k es - 9}$

------------------------------------------------------------

Translation in English:

Step 1 : Swap the sides of the equation

Step 2 : Divide both sides by 14

Step 3 : Calculate
