The half life of the substance is 6.92 days.
<h3>What is the Half life ?</h3>
Half life can be defined as the time required to reduce the concentration to half of its initial value.
Here the equation given is

The concentration will reduce to half therefore

so,

ln 0.5 = - 0.1001 * t(1/2)
-0.693 = -.1001 * t(1/2)
t(1/2) = 6.92 days.
Therefore the half life of the substance is 6.92 days.

Answer:
Step-by-step explanation:
Given:
1/2(ln(xx + yy) − ln(zz))
Now,
From the properties of log function,
1) n × ln(x) = ln(xⁿ)
and,
2) ln(A) - ln(B) = 
applying the properties in the given equation
we get the above equation as:
( using the property 2 we get (ln(xx + yy) − ln(zz) =
or
⇒
( using the property 1 i.e n × ln(x) = ln(xⁿ) )
expression as an equivalent expression with a single logarithm is

Answer:
30/1000
Step-by-step explanation:
red has a chance of 3/10
purple has a chance of 2/10
yellow has a chance of 5/10
for probability, multiply the denominators together, and the numerators together
3*2*5 = 30
10*10*10 = 1000
So the probability of picking red, then purple, and then yellow with replacement is 30 of 1000
