In AWXY, the measure of ZY=90°, XW = 89, WY = 80, and YX = 39. What ratio
represents the cosine of ZX?

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

where did you get them? if you picked from the grass, is is probably poisonous.

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

i would say c
