a gold mine has two elevators, one for equipment and another for the miners. the equipment elevator descends 5 feet per second. the elevator for the miners descends 17 feet per second. one day, the equipment elevator begins to descend. after 26 seconds, the elevator for the miners begins to descend. what is the position of each elevator relative to the surface after another 16 seconds? at that time, which elevator is deeper?

5x26=130 5x16=80

130+80=210

-210 feet = the equipment elevators position after 32 seconds

17x16=272

-272 feet = the miners elevators position after 32 seconds

The miners elevator is deeper. The answers are negatives due to the position being relative to the surface.

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
