Answer:
Step-by-step explanation:
Given function: 
To find 
, simply input 
into the function:
The answer is D because microcosm is a community displaying characteristics of something larger.
The amount of the substance (At) at any time t is calculated through the equation,
At = (A0)(e^-kt)
where A0 is the initial amount and k is constant.
For the half-life,
ln (At / A0) = ln 0.5 = -k(5270 years)
The value of k is 1.3153x10^-4 / year.
Substituting this value to the same equation, where At = 0.25A0
ln 0.25 = -(1.3153 x 10^-4)(t)
The value of t from this equation is 10540 years. The closest value to this is letter A.
Answer:
ok........ ......... ..... .....
Solve your equation step-by-step.
Simplify both sides of the equation.
6=4(2n−3)
6=(4)(2n)+(4)(−3)(Distribute)
6=8n+−12
6=8n−12
Flip the equation.
8n−12=6
Add 12 to both sides.
8n−12+12=6+12
8n=18
Divide both sides by 8.
8n/8=18/8
n=9/4
