Question

A square with vertices at (4, 6), (2, 3), (5, 1) and (7, 4) is rotated 90° clockwise. Its new coordinates are:
Select one:
a. (–4, –6), (–2, –3), (–5, –1) and (–7, –4)
b. (3, –2), (6, –4), (4, –7) and (1, –5)
c. (–6, 4), (–3, 2), (–1, 5) and (7, –4) INCORRECT
d. (–4, 6), (–2, 3), (–5, 1) and (–7, 4)

Answer 1

C is wrong and I dont know what to do
:?

Answer 2

I think D is correct because i get 6,-4 , 3,-2 , 1,-5 , 4,-7 which is like d but backwards

Answer 3

@MrNood

Answer 4

maybe something is wrong with the answer choices or question ..

Answer 5

that's not D
the rule we use for clockwise rotation is \[\huge\rm (x,y) \rightarrow (y, -x)\]

Answer 6

for 90 clockwise rotation

option D is `d. (–4, 6), (–2, 3), (–5, 1) and (–7, 4)`

Answer 8

yeah i know that eqation so the real answer isnt one of the choices?

Answer 9

your answer is correct u got `6,-4 , 3,-2 , 1,-5 , 4,-7`
that's correct so new coordinates are (6,-4)(3,-2)(1,-5)(4,-7)
now the domain is 6,3,1,4 ( all x values )

Answer 10

are you sure u typed hat correctly ?

Answer 11

that**

Answer 12

Yes i guess its not one of the answer choices can you help me with something else?

Answer 13

and you sure it's `90 clockwise` not 180 clockwise ?

Answer 14

yes it says 90

Answer 15

hmm not sure then

Answer 16

what about this one for dilation i thought you just doubled it
A triangle has side lengths of 12, 15 and 9. A dilation could result in a triangle with which of the following side lengths?
Select one:
a. 4, 7 and 1
b. 2, 3 and 3
c. 24, 30 and 20 Incorrect
d. 4, 5 and 3
