Terrance claims that for the input coordinates (x, y), a rotation of 180° clockwise about the origin, followed by a reflection o
vodka [1.7K]

Answer:

Terrance is incorect.

Correct output coordinates (-y,-x)

Step-by-step explanation:

Let (x,y) be the input coordinates.

First translation is a rotation of 180° clockwise about the origin. This translation has a rule

(x,y)\rightarrow (-x,-y)

Second translation is a reflection over the line y = x. The general rule for the reflection across the line y=x has the rule

(a,b)\rightarrow (b,a)

When a sequence of two translations are applied to the initial input coordinates, then

(x,y)\rightarrow (-x,-y)\rightarrow (-y,-x)

As you can see Terrance made a mistake and these two transformations do not cancel themselves out.

Fittoniya [83]

The travels you have described are:

                                       (Middle floor) + 8 + 5 - 9 + 7 - 32

                                   =  (middle floor)  + 20 - 41

                                   =  (middle floor)  -  21  brought her to floor #1.

So                                   Middle floor  -  21  =  1

Add 21 to each side:    Middle floor  =  22 

The building has (2 x middle floor)  =  44 floors.
