A fossil is found that contains 10% of the amount of carbon-14 found in a living being about how old is the fossil?
1 answer:
Answer: 19200 years
Step-by-step explanation:
The fossil in the above question has aged for 3.3 half lives. Since the half life of a fossil is given as 5730 years, the age of the fossil will be given as:
= 5730 years × 3.3333333
= 19200 years
Therefore, the age of the fossil is 19200 years.

Answer:
f(2)=18
Step-by-step explanation:
f(2)=3(2+4)
=(6+12)
=18
point slope form
y-y1 = m(x-x1)
y-1 = 6(x-(-2))
y-1 = 6(x+2)
to change it into slope intercept form
distribute
y-1 = 6x+12
add 1 to each side
y = 6x+13
the y intercept is 13
