Segment b prime c prime has endpoints located at b'(2, 0) and c'(2, 6). segment bc was dilated at a scale factor of 2 from the origin. which statement describes the pre-image?

First option.

Step-by-step explanation:

In this case you know that the segment BC was dilated from the origin, producing the image B'C', whose endpoints are:

The image BC was dilated with a scale factor of 2. This means that each coordinate of the endpoints of BC was multiplied by 2.

Therefore, you can conclude that the segment  BC is one-half the size of the segment B'C'.

 So, you can divide each coordinate of B' and C' by 2 in order to find the coordinates of the points B and C.

Then:

B→

C→

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
