The half life formula is :
where N(t) = remaining quantity after t years
No = Original Quantity
t = time in years
T = half life in years
From the problem, we have :
N(t) = 30 grams
No = 100 grams
T = 674
Solve for t :
Take ln of both sides :
The answer is t = 1170.71 years
15 ~ 3 - (14~2) just a note, this ~ means the division sign
C because 4 1/3= 13/3
Then (13/3)x9= 39
Lastly 39+4= 43
The region enclosed by the given curves are integrated with respect to x and the area is 4.2724 square units.
In this question,
The curves are y = 2/x, y = 2/x^2, x = 4
The diagram below shows the region enclosed by the given curves.
From the diagram, the limit of x is from 1 to 4.
The given curves are integrated with respect to x and the area is calculated as
⇒
⇒
⇒
⇒
⇒ A = 2[(1.3862-0.25) - (0-1)]
⇒ A = 2[1.1362 + 1]
⇒ A = 2[2.1362]
⇒ A = 4.2724 square units.
Hence we can conclude that the region enclosed by the given curves are integrated with respect to x and the area is 4.2724 square units.

Answer:
28.84
Step-by-step explanation:
Simplify the inside of root first
147 / 3 = 49
49 + 3 = 52
4 (root) 52 = 28.8444102
