Mean= average( add all numbers and divide by the amount of numbers)
median=the middle number
mode= the number that occurs the most ( there can be multiple)
midrange= the average of the smallest and largest numbers

The scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

<h3>What is the dilation of the figure?</h3>

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

Point c is the center of dilation. Line segment BA is dilated to create line segment b prime, a prime. The image of the given problem is attached below. The length of CA is 4.

$CA=4$

The length of a prime is 16.

$AA'=16$

The new dimension will be,

$CA'=CA+AA'\\CA'=4+16\\CA'=20$

Now, the scale factor is the ratio of the new dimension to the original dimension. Thus, the scale factor of the dilation is,

$r=\dfrac{20}{4}\\r=5$

This will be the same for the line segment BA. Thus, the scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

Emanuel has 745 pictures in his phone.His memory is getting full, so he starts deleting 20 pictures every day. Define each varia

BigorU [14]

Let f be the function with variable n, which gives the number of pictures left in the phone after deleting pictures for n-days.

So f(1) gives the number of photos left after 1 day of deleting photos

f(2) gives the number of photos left after 2 days of deleting photos

and so on.

f(1)=745-20
f(2)=745-20-20=745-20*2
f(3)=745-20-20-20=745-20*3

so clearly f(n)=745-20n

Answer:

the algebraic expression is f(n)=745-20n,

where n is the n'th day of deleting photos, and f is the number of photos left after n days of deleting.
