Best ResponseYou've already chosen the best response.2A dilation with a factor of 1/2 will make the figure bigger or smaller?

Best ResponseYou've already chosen the best response.0bogger i would hope

Best ResponseYou've already chosen the best response.2A dilation factor of 2 will make the figure twice as big as the original, a dilation factor of 3 will make the figure three times as big as the original, So rethink for a factor of 1/2!

Best ResponseYou've already chosen the best response.0oh i think i see so the figure would be smaller i guess

Best ResponseYou've already chosen the best response.2So do we agree that a scale factor of more than one will make the image bigger, and a scale factor of less than one will shrink the image (even it's called dilation).

mathmate

Best ResponseYou've already chosen the best response.2Good! So a factor of 1/2 will shrink the original to what size? For example, you have a point P(1,2). Dilation factor of 2 will bring it to P'(2,4). Dilation factor of 3 will bring P'(3,6). What would be the coordinates of P' using a dilation factor of 1/2?

Best ResponseYou've already chosen the best response.2Remember that 1/2 means \(\frac{1}{2}\), or 0.5.

Best ResponseYou've already chosen the best response.0actual would it be 1,1

Best ResponseYou've already chosen the best response.0sorry i was using multiplication for my answers but that would make more sens 1/2 is 50 so in dilation it would be 0,5 sorry for my stupidity

Best ResponseYou've already chosen the best response.2So please explain how you got (1,1).

Best ResponseYou've already chosen the best response.0well i thought i seen a pattern with the 2,4 being 4 2x2 would be 4 and 3 x 2=6

rayman5766

Best ResponseYou've already chosen the best response.0so i thought 1 would equal 1.1 but i forgot it was a 1/2 wich would make it 0.5 sorry i think of some other thing wich would make it the answer

rayman5766

Best ResponseYou've already chosen the best response.0also i keep putting wich and now which

Best ResponseYou've already chosen the best response.2Good, the fact is that each of the (x,y) coordinates must be multiplied by the scale factor. For example, if we apply a factor of 1.5 to P(2,5), we would get P'(2*1.5, 5*1.5)=P'(3,7.5). So can you try again?

Best ResponseYou've already chosen the best response.0ha good one you see when i think of math i think of possibility's so i think of this which would make that

Best ResponseYou've already chosen the best response.2Just in case our original question was lost: For example, you have a point P(1,2). Dilation factor of 2 will bring it to P'(2,4). Dilation factor of 3 will bring P'(3,6). What would be the coordinates of P' using a dilation factor of 1/2?

Best ResponseYou've already chosen the best response.2The answer to \(my\) question, P(1,2) with a factor of 0.5 is P'(1*0.5, 2*0.5) = P'(0.5,1) (use a calculator if you need to) Understand how the above problem was solved before thinking about the problem you are trying to solve. Math is about understanding. We should always understand how to solve a class of problems BEFORE attempting exercises on the topic. Guessing will only make math hard, for now and for the future.

Best ResponseYou've already chosen the best response.0also that would make sens knowing 1/5 is 0.5 oki thik i get it
