Answer:
4%
Step-by-step explanation:
1/25 = 0.04 = 4%
To see if it’s linear use a pencil and see if any lines touch more than one point (just look up pencil line test) and 1-4 just draw out a graph (and since it goes up to hundred don’t count by 1s count by 10 or or something
Hope you kind of get the idea sorry I’m not the best at explaining stuff :)
Answer:
the last one
Step-by-step explanation:
it is the one which is the most fair and would make sense, I don't exactly know how to explain it sorry
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
