Dang, you're an elementary school er? Good grief i'm and 8th grade math one student!
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
For this case we have to:
"two to the third power" is equivalent to the algebraic expression: 
Therefore, we can rewrite the expression given as:
Thus, the value of the initial expression is: 4
Answer:
The sure thing about the graph is that the amplitude is at 3 and -3. Amplitude<span>, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.</span>
