9514 1404 393
Answer:
16 square units
Step-by-step explanation:
The figure is a square with side lengths 4.
The area is 4×4 = 16 square units.
Answer:is B
Step-by-step explanation:
You can use the divergence theorem:

has divergence

Then the rate of flow out of the cylinder (call it <em>R</em>) is

(by divergence theorem)

(after converting to cylindrical coordinates)
whose value is 0.
Answer:
Answer:1.5*10^9 years
Step-by-step explanation:
The half life of the substance is given i.e 4.5B years. You can change it into seconds by multiplying it with 365 and 86400.
The current no of particles is given 78.88% which will be equal to 78.88 if you assume the substance had 100 no of particle initially.
Determine the decay constant by dividing 0.69 by half life
use these values in the equation for the answer.
[ln and e are inverse functions to eachother]
