A sample of a radioactive isotope had an initial mass of 650 mg in the year 2003 and decays exponentially over time. A measurement in the year 2005 found that the
sample's mass had decayed to 490 mg. What would be the expected mass of the
sample in the year 2007, to the nearest whole number?

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
