The price of a stock decreased by $.60 one week, decrease $.10 the next week and decrease another $.20 the following week what is the average change in price of a stock over the three weeks

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

source:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

0

step-by-step explanation:

equals the constant of proportionality.

solve for

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
