Base 8 representation of 112 work out
erastovalidia [21]
To convert a decimal (112) to base 8, divide by eight, keep the quotient and remainder.  Repeat with the quotient.

112/8=14 R0
14/8=1 R6
1/8=0 R1

Read the remainders from bottom to top to get 160 (base 8) = 112 (decimal)

Use the Polygon tool to draw the image of the given quadrilateral under a dilation with a scale
Nataly [62]

Answer: See the picture 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=\frac{2}{3}

Since:

0

It is a Reduction.

You can identify that the vertices of the quadritaleral are:

(-3,0),(-9,-3),(-6,-9),(3,-6)

 So you need to multiply the coordinates of eac vertex by \frac{2}{3} in order to get the coordinates of the image.

Then, you get:

(\frac{(-3)(2)}{3},0*\frac{2}{3})=(-2,0)\\\\(\frac{(-9)(2)}{3}),\frac{(-3)(2)}{3})=(-6,-2)\\\\(\frac{(-6)(2)}{3},\frac{(-9)(2)}{3})=(-4,-6)\\\\(3*\frac{2}{3},\frac{(-6)(2)}{3})=(2,-4)

Now you can plot the points and draw the image of the given quadrilateral.

See the picture attached.
