Assume that a DVD loses 20% of its value every year it is in a video store. Suppose the initial value of the DVD was $60.​

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

55 degrees because 55+55=110 degrees

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.
