Question

In the graph below, find the coordinate of the image point. O is the origin and P is the point (4, 3). Ry and Rx are reflections around the x- and y- axes.
Complete the following:

HpHo : (3, 0) --->

Answer 1

@satellite73

Answer 2

i totally don't understand this question

Answer 3

what does HpHo mean?

Answer 4

can you attach the question as it is written?

Answer 5

i think h means half or rotates 180 degrees
and its (Hp) (Ho)

Answer 6

sorry i am really lost
any way to attach the question?

Answer 7

mmmm maybe a screen shot?

Answer 8

yeah that might help

Answer 9

you have \(R_x\) in the problem, but no \(R_x\) in the question
i am totally confused

Answer 10

wow i would really like to help, but his is greek to me. i have no idea what \(H_0\) means in this context
there is no \(H\) in the text part

Answer 11

have you seen another problem like this? or any explanation? an example?

Answer 12

yes someone told me it was a half roatation around "p for example

Answer 13

"p"

Answer 14

or a 180 degree around the given point which is "p" in this case

Answer 15

so maybe a half rotation around \((0,0)\) would take \((3,0)\) to \((-3,0)\)?

Answer 16

but then you have to roate it around "o"

Answer 17

no i think you do the right one first

Answer 18

that is usually the way you read something like \(H\circ G\) to \(G\) first then \(H\)

Answer 19

the person that told me that said do whatever one is closest to the original point

Answer 20

so my guess (and it is really only a guess) is that first you take \((3,0)\) and rotate it 180 degrees about \((0,0)\) to get \((-3,0)\) and then rotate it 180 degrees about \((4,3)\) to get \((11,6)\)

Answer 21

yeah the one "closest" to \((3,0)\) is \(H_0\)

Answer 22

and \(H_0\) means (apparently) rotate 180 degrees about \((0,0)\)

Answer 23

so my best guess is \((11,6)\)
is there any way you can check the answer to see if it is right?

Answer 24

if you don't mind me saying so, this is one weird retricequestion

Answer 25

okay thanks are you busy or can you help some ?

Answer 26

sure i can help some if i can figure out the question

was that answer correct?

Answer 27

yes i t was:)

Answer 28

yay!

Answer 29

If a translation maps point (3, 2) to (4, 5); or T : (3, 2) (4, 5), indicate the image for (2, 4).

Answer 30

ok we can try another if you like

Answer 31

yippy!

Answer 32

my best guess is right one up three so for this one try \((3,7)\)

Answer 33

let me know if it seems right

Answer 34

Using the given figure, the square ABCD is transformed to a new location.

The transformation shown is

Answer 35

idk how to figure that other one out i hop eits right idk

Answer 36

T : (3, 2) (4, 5)

from 3 to 4 is right one unit
from 2 to 5 is up 3 units

Answer 37

so i am figuring that the translation is "right 1, up 3"
that is all

Answer 38

i am not sure what the question is for the third one you posted
it looks like the translation is "right 5, up 2" but i am not sure what notation you are using to indicate that

Answer 39

maybe something like
\[(x,y)\to (x+5,y+2)\] ? i don't know what notation you are supposed to use

Answer 40

okay ty

Answer 41

look familiar?

Answer 42

yes i t def does

Answer 43

ok good

Answer 44

The rotation R maps all 60° about O the center of the regular hexagon. State the image of B for the following rotatio
R2=

Answer 45

what on earth is B ?

Answer 46

i bet that helps

Answer 47

if R is a 60 degree rotation, that i figure \(R^2\) is a 120 rotation

Answer 48

so in that picture, B would go to F

Answer 49

that is, if i am interpreting R2 correctly as \(R^2\)

Answer 50

how we doing so far? you realize i hope that i am making a guess as to what the question is asking

Answer 51

i think the roation is forward instead o backwards on the wheel

Answer 52

could be i suppose, but in math a 60 degree rotation almost always means counter clockwise

Answer 53

if you are told different, then i believe you
it is hard to know without instructions

Answer 54

ikr i hate when they give poor instructions

Answer 55

yeah, a text usually helps, or at least an example

Answer 56

For the transformation T, what is T-1?

T : (x, y) --> (x + 4, y + 3)

T-1: (x, y) --->

Answer 57

that is an easy one
\[T:(x,y)\to (x-4,y-3)\]

Answer 58

A transformation named T maps XYZ to X'Y'Z'.
The transformation shown is a

Answer 59

what are your options?

Answer 60

glide? i have heard that, but i am not sure
i assume you have choices for this

Answer 61

reflection
translation
dilation

Answer 62

translation
it translated to the right

Answer 63

Based on the graph, the coordinates for DO, 1 of X are

Answer 64

?

Answer 65

maybe another screen shot for this one

Answer 66

there is no DO in the picture, and i have no idea what "1 of X" means

Answer 67

ok \(x\) is \((4,0)\) but what is \(D_{0,1}\) supposed to mean? any idea?

Answer 68

if it is a dilation, then i think maybe it stays the same

Answer 69

it is really hard to do this without knowing what the notation means
any idea?

Answer 70

i think its dilation

Answer 71

but by how much? what happens if you click on "help" does it say? it must somehow depend on both 0 and1 in the subscript of \(D_{0,1}\)

Answer 72

yeah your right it stays the same . and if i press help then nothing happens

Answer 73

really? not much help then is it?

Answer 74

hahhaha nope

Answer 75

this one i understand
if you rotate that thing 180 about the origin then \((1,-2)\) will go to \((-1,2)\)

Answer 76

help does nothing
how are you supposed to learn this then?

Answer 77

hahahahah i teah myself or ask for help on here

Answer 78

i see...
