Answer:

The correct option is 2.

Step-by-step explanation:

If a figure rotated 270°counterclockwise with origin as the center of rotation, then

$(x,y)\rightarrow (y,-x)$

From the given graph it is clear that the coordinates of V are (1,3), the coordinates of V' are

$V(1,3)\rightarrow V'(3,-1)$

The coordinates of V' are (3,-1).

Therefore the correct option is 2.

What is the domain and range of the relation shown in the table?

TEA [102]

Answer:

domain: {10,15,19,32}

range:{5,9,-1}

Step-by-step explanation:

As we know domain is the values of input and range is the values of output.

Here , x is the input and y is the output.

$\left[\begin{array}{cc}x&y\\10&5\\15&9\\19&-1\\32&5\end{array}\right]$

Thus the input values according to the given problem is : 10 ,15 , 19, and thus ,

⇒The domain would accordingly be these four numbers : 10 , 15 , 19 , 32.

Note that we donot have any information regarding the other values of x.

The range is : { 5,9,-1 } only as the 5 is repeated in two cases .

Range is unique and there must be not repetition. Thus the apt answer would be :

domain: {10,15,19,32}

range:{5,9,-1}

An escalator lifts people to the second floor of a building, 28 ft

Marysya12 [62]

9514 1404 393

Answer:

56 ft

Step-by-step explanation:

The geometry can be modeled by a right triangle with an unknown hypotenuse, and a side opposite the 30° angle that is 28 ft.

sin(30°) = (28 ft)/hypotenuse

hypotenuse = (28 ft)/sin(30°) = 56 ft

The length of the escalator is 56 feet.
