Answer:
Step-by-step explanation:
66=2(w+5)+2w L=14+5
66=2w+10+2w L=19
66=4w+10
-10
56=4w/4
14=w
Answer:
10
Step-by-step explanation:
h(x) = 6 - x
(h o h)(x) = h(h(x)) = 6 - h(x) = 6 - (6 - x) = 6 - 6 + x = x
(h o h)(x) = x
(h o h)(10) = 10
Answer: C. 13,839 (the answer is not among the given options, however the result is near this value)
Step-by-step explanation:
The exponential decay model for Carbon-
14 is given by the followig formula:
(1)
Where:
is the final amount of Carbon-
14
is the initial amount of Carbon-
14
is the time elapsed (the value we want to find)
On the other hand, we are told the current amount of Carbon-14 is , assuming the initial amount of Carbon-14 is :
(2)
This means: (2)
Now,finding from (1):
(3)
Applying natural logarithm on both sides:
(4)
(5)
(6)
Finally:
This is the age of the paintings and the option that is nearest to this value is C. 13839 years
