Answer:
no
Step-by-step explanation:
Let f represent the fraction of C-14 remaining as a function of the time t in years. Since the half-life of C-14 is about 5570 years, we have ...
f = (1/2)^(t/5570)
Taking the log and solving for t, we get ...
log(f) = (t/5570)log(1/2)
5570·log(f)/log(1/2) = t
Filling in the given value for f, the value of t we get is ...
5570·log(0.65)/log(0.5) = t ≈ 3462
It appears the estimate of 4000 years is a bit high.
You add each number to get the next number and you find that the answer is 146:D
Answer:
g(x) = 4x - 1
Step-by-step explanation:
We have that:
So
Equaling both sides:
b = -1.
And
Then
g(x) = 4x - 1

Answer:
orange: 0.2$, apple: 0.4$
Step-by-step explanation:
we mark the price of an orange x and the price of an apple y. then we write down Maggie's and Tanya's purchases as a set of equations:
10 oranges and 5 apples for 4$ means:
9 oranges and 3 apples for 3$ means:
we use the second equation to isolate y:
and plug it in the first equation:
and then we find y:
