Answer:
Step-by-step explanation:
Let
x ----> the number
we know that
The word "at least" means "greater than or equal to"
6 times a number is the same that multiply the number by 6
so
The inequality that represent this situation is

Step-by-step explanation:
it is just rearranged
Remember that when there is no sign in front of the first one, there is an invisible plus/positive sign
Answer:
1845 years
Step-by-step explanation:
Decay of Carbon-14 is usually modeled by an exponential function. It x is the number of years since the original amount was brought into existence, then the fraction remaining (y) is modeled by ...
... y = (1/2)^(x/5730)
We want to find the value of x when y = 80% = 0.80. The equation is then ...
... 0.80 = 0.50^(x/5730)
Taking logarithms, we get
... log(0.80) = (x/5730)·log(0.50)
Multiplying by the inverse of the coefficient of x, we have
... x = 5730·log(0.80)/log(0.50) ≈ 1845 . . . . years
