If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
It depends on the line or parabola that you are talking about, more information would be needed to answer this correctly.
Answer:
The greatest common factor is 4
Step-by-step explanation:
1.Find the prime factorization of 12
a) 12 = <u>2</u> × <u>2</u> × 3
2.Find the prime factorization of 196
a) 196 =<em> </em><u>2</u> ×<u> 2</u> × 7 × 7
To find the GCF, multiply all the prime factors common to both numbers:
a)GCF=2x2
Therefore, GCF = 2 × 2
GCF = 4
I think the answer will be B. Hope it help!
