which of the following is a geometric sequence 1. 1,1,2,3,5,... 2. 1, 1/2, 1/4, 1/8, ... 3. 2,4,6,8 4. 7,4,1, -2

2/5

step-by-step explanation:

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

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
