=(-5 x 4 x 1)^-2
= (-20)^-2
= 1/(-20)^2
= 1/400

Graph the image of this quadrilateral after a dilation with a scale factor of 4 centered at the origin

Brut [27]

Answer: The image is attached.

Step-by-step explanation:

A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".

In this case we know that the scale factor is:

$scale\ factor=4$

Since:

$4>1$

It is an Enlargement.

You can identify that the vertices of the pre-image shown in the figure, are:

$(-2,1)\\\\(-1,2)\\\\(0,0)\\\\(-1,-2)$

So you need to multiply the coordinates of those vertices by 4 in order to get the coordinates of the image;

$((-2)(4),1(4))=(-8,4)\\\\((-1)(4),(2)(4))=(-4,8)\\\\((0)(4),(0)(4)=(0,0)\\\\((-1)(4),(-2)(4))=(-4,-8)$

Now you can draw it (The image is attached).

Select the correct answer.<br> Find the value of g(7) for the function below.<br> g(x) = zur

ale4655 [162]

Answer:

Step-by-step explanation:

To evaluate g(7) substitute x = 7 into g(x) , that is

g(7) = $\frac{7}{8}$ × 7 - $\frac{1}{2}$

= $\frac{49}{8}$ - $\frac{4}{8}$

= $\frac{45}{8}$ → B

Consider the image of EFGH for the translation (x, y) → (x – 3, y + 1). What is the ordered pair of F′?

omeli [17]

Answer:

$F'(-1,3)$

Step-by-step explanation:

The rule for the translation is given as

$(x,y)\rightarrow (x-3,y+1)$

The coordinates of F are (2,2).

We substitute these coordinates into the translation rule to find the coordinates of F'.

$F(2,2)\rightarrow F'(2-3,2+1)$

$F(2,2)\rightarrow F'(-1,3)$
