Answer:
2441.95 years
Step-by-step explanation:
We can model this exponencial function as:
P = Po * (1+r)^(t/n)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the period of half-life.
In this case, we have that P/Po = 100% - 25.5% = 74.5% = 0.745, r = -0.5 and n = 5750, so we have that:
0.745 = (1 - 0.5)^(t/5750)
Step 1: log in both sides:
log(0.745) = (t/5750) * log(0.5)
Step 2: isolate t
t = 5750*log(0.745)/log(0.5) = 2441.95 years
Answer:
b^(-6)
Step-by-step explanation:
The numerator of this fraction is b^(-11). The -11 is the sum of -4 and -7.
The denominator is b^(-5).
Recall that b^a / b^c = b^(a - c). Thus, b^(-11) / b^(-5) = b^(-6)
