A dilation has the center (0,0). Find the image of the point (3,11), given a scale factor of 3.

Question

amistre64 · Answer

(3*3, 3*11) id assume

amistre64 · Answer

since the dilation is determined from the center, then everything is 3 times as far away from the center as it was

anonymous · Answer

so it would be (3,3) 3,11)?

amistre64 · Answer

... no

amistre64 · Answer

your notation doesnt even make sense ...

amistre64 · Answer

scale the given points components by a factor of 3

anonymous · Answer

i dont get it

amistre64 · Answer

i have to assume that if you ask this level of a math question, that you must of had some prior experience to fall back on.

The "IT" that you dont get could be anything at this point.  Can you be more specific as to what you dont get?

i dont get how to get theanswer

http://www.wolframalpha.com/input/?i=dilation&a=*C.dilation-_*MathWorld- this shows a picture of a triangle being dilated

amistre64 · Answer

you are told in the question that you have a point at (3,11)  and that it is dilated to a different point by a factor of 3

amistre64 · Answer

if something is 3 times as far away; then that means all of its linear parts are 3 times as far away as well

amistre64 · Answer

so the answer would be to multiply this point by 3 in order to get the NEW coordinate under the dilation

anonymous · Answer

so it woulkd be(9,33) ?

amistre64 · Answer

yes :)

anonymous · Answer

oh ok i get it now, thanks foryour help (:
