Answer:
1000
Step-by-step explanation:
Answer: The red submersible started from a higher altitude and the red submersible rose faster.
Step-by-step explanation:
We know that 172 of them were wood, so the rest are metal. To find that number we do:
276 - 172 = 104 metal pins.
To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:
104/276 is about 0.3768.
Multiply this by 100:
37.68
So, the percent of metal pins is 37.68%.
Answer:
The solution proves that the equation has a non-trivial solution.
Step-by-step explanation:
We want to show that the equation has nontrivial solutions for which 
Let
be a set of non-zero numbers such that that 
Because T is a linear solution:

= 
= 
= 
= 
= 0
This shows that
are linearly independent with the mapping resulting in a non-trivial solution.
Answer:

Step-by-step explanation:
The general formula for exponential decay given a half-life
is
where N(t) is the amount at time t,
is the initial amount (at time t=0), and
is the half life of the substance.
The half life of carbon-14, is approximately 5,730 years.
= 5730 years
= 6 milligrams
Therefore:
Amount of carbon-14 remaining in the bone fragment after t years is:
