How many push ups can nathan do in 7 days?

21 I think. i did it in my head:p

well, first you need to find out how many minutes of push- ups he does in one day. you can divide that. After finding the number you add.

(sorry if this doesn't work)

a=r

d=q

c=p

b=s

hope this !

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
