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.

Answer:
4x5x4x7x4x9x2x1x43x125
Step-by-step explanation:
Equation 1) 3x = 9 - 6y
Equation 2) 3x + 8y = 9
Add 6y to both sides in equation #1.
1) 3x + 6y = 9
2) 3x + 8y = 9
Subtract equations from one another.
-2y = 0
Divide both sides by -2.
y = 0
Plug in 0 for y in the first equation.
3x = 9 - 6y
3x = 9 - 6(0)
Simplify.
3x = 9 - 0
Simplify.
3x = 9
Divide both sides by 3.
x = 3
So, x = 3, y = 0
~Hope I helped!~
Answer:
see explanation
Step-by-step explanation:
If f(x) and 
are inverse functions, then
f()(x) = x
Thus substitute x = (x) into f(x)
f(
)
= 5 ( ) - 6
= x + 6 - 6
= x
Thus f(x) and (x) are inverse functions
