Pre image ABCD was dilated to be image A’B’C’D, where the center of dilation is the origin. What scale factor was used in the di

ArbitrLikvidat [17]

Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

$\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}$

Find the scale factor

Looking at the graph

we have

$A'B'=1\ unit\\AB=4\ units$

Let

z ---> the scale factor

$z=\frac{A'B'}{AB}$

substitute the values

$z=\frac{1'}{4}=0.25$

Choose one of the factors of x15 − 64. (2 points)

Lorico [155]

We have been given the function $x^{15}-64$

Convert this expression in difference of cubes form.

$x^{15}-64\\=(x^5)^3-4^3$

Now, in order to find the factors, we can apply the difference of cubes form, which is given by

$x^3-y^3=(x-y)(x^2+xy-y^2)$

On applying this formula, we get

$(x^5-4)(x^{10}+4x^5+16)$

Hence, the factors of the given expression are

$(x^5-4) \text{ and }(x^{10}+4x^5+16)$

Out of the given option, A is the correct option.

x^5 − 4 is the required factor.
