$1.05 is my answer taht I got for this question.
Answer:
25.9 years
Step-by-step explanation:
The half life of an isotope is related to the actual amounts by the equation:
N = Ni*(1/2)^(t/HL)
where N and Ni are the final and initial (Ni) amounts, t is the time (in years for this problem) and HL is the half-life, in years.
In this problem, we can write:
100 = 360*(1/2)^(x/14)
I'll reduce this to:
1 = 3.6*(1/2)^(x/14)
This can be solved by taking the log of both sides.
x = 25.87 or 25.9 years
You can make a proportion
<em>Cross multiply</em>
8 × 6 = 48
<em>Now, divide 48 by 9</em>
48 ÷ 9 = 48/9
x = 48/9
Answer:
Step-by-step explanation:
<u>Find the y-intercept of f(x):</u>
The y-intercept of g(x) is 3 as per graph.
<u>Solve for a:</u>
- g(0) = a*f(0)
- 3 = a*1
- a = 3
