12/15 = 400/500
500 people took the survey.
Answer: 8x^2° + 52x° + 27°
Using the knowledge i know i think this is the right answer
Have a great day :)
Y=mx+b // standard form
3x=12-2y
2y=-3x+12
y=-3/2x+12/2
y=-3/2x+6
So the answer is: y = -3/2x+6
Actually the position function with respect to time under constant acceleration is:
a=g
v=⌠g dt
v=gt+vi
s=⌠v
s=gt^2/2+vit+si
So if vi and si are zero then you just have:
s=gt^2/2
Notice that it is not gt^2 but (g/2) t^2
So the first term in any quadratic is half of the acceleration times time squared because of how the integration works out...
Anyway....
sf=(a/2)t^2+vit+si
(sf-si)-vit=a(t^2)/2
2(sf-si)-2vit=at^2
a=(2(sf-si)-2vit)/t^2 and if si and vi equal zero
a=(2s)/t^2
