Answer:
1.5 billion years = 3.33 meters
From the end 2.22\times 10^{-5} meters is the distance of written history.
Step-by-step explanation:
Age of earth is 4.5 billion years and we have to represent the history of earth (from birth to present ) with a 10 meter long timeline.
So on the scale every meter will represent 4.5/10 = 0.45 billion years.
∵ 0.45 billion years represent the distance = 1 meter on scale.
∴ 1 billion years will be represented by =
∴ For 1.5 billion years distance will be =
Now we have to measure the length of written history from the end of the timeline.
Since written human history extends about 10000 yrs back means distance on timeline = = from the end.
Y=4x+3 that's what I think
Alright, so the distance formula is sqrt((x1-x2)^2+(y1-y2)^2), and plugging that in, we get sqrt((0-3)^2+(3-10)^2)=sqrt((-3)^2+(-7)^2)=sqrt(9+49)=sqrt(58)=around 7.6
