Rectangle A’B’C’D’ is the image of rectangle ABCD after dilation. What is the scale factor of the dilation?

Alecsey [184]

Answer:

The scale factor of the dilation is 3

Step-by-step explanation:

we know that

A dilation is a non rigid transformation that produce similar figures

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

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional

Let

z ----> the scale factor

$z=\frac{D'C'}{DC}$

we have

$D'C'=12-3=9\ units$ ----> difference of x-coordinates

$DC=4-1=3\ units$ ---> difference of x-coordinates

substitute

$z=\frac{9}{3}=3$

The scale factor is greater than 1

The dilation is a enlargement

It takes 16 minutes for a certain bacteria population to double. If there are 6,140,276 bacteria in this population at 9:15 AM w

ZanzabumX [31]

Answer:

The answer to your question is: 24 561 104 bacteria

Step-by-step explanation:

every 16 minutes bacteria population double

There are 6140276 bacteria at 9:15 AM

estimate bacteria at 9:47

First calculate the minutes : 47 - 15 = 32 minutes

and 32 / 16 = 2

then 2 times the bacteria population double

So,

first time = 6140276 x 2 = 1 2280552 bacteria

second time = 1 2280552 x 2 = 24561104 bacteria
