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.

Answer:
|x| > 1
Step-by-step explanation:
The absolute value inequality
|X| > k
where X is an expression in x and k is a non-negative number is solved by solving the equivalent compound inequality
X < -k or X > k
Here you are working backwards. You know you want the compound inequality to be
x < - 1 or x > 1,
so using the variable expression x for the expression X and 1 for k, write the absolute value equation
|x| > 1
Answer:
0.50
Step-by-step explanation:
0.30 + 0.20 = 0.50
(That answer feels almost too easy so I am not positive. I would wait for other answers to come in before submitting for your quiz/homework)
Answer:
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the function
y = f(x) = 3 x ( 4 x + 7)
y = 3 x ( 4 x + 7)
y = 12 x² + 21 x ..(i)
Differentiating equation (i) with respective to 'x' , we get
