Answer:
λ = 1.3252 x 10⁻⁴
Step-by-step explanation:
Since we are already given the half-life, the decay expression can be simplified as:

For a half-life of t =5230 years:

The decay-rate parameter λ for C-14 is 1.3252 x 10⁻⁴
Answer:
x=19
Step-by-step explanation:
2x - 8 = 30
get x by itself by adding 8 to both sides
2x=38
divide by 2
x=19
Ron runs the fastest
Brooke runs 9.4 feel per second
Adam runs 10.4 feet per second
And if you times 15 * 60 you get 900
And if you times 15 * 9 which is 135 which only proves Ron’s the fastest
