Answer:
t = ln(0.5)/-r
Step-by-step explanation:
The decay rate parameter is missing. I will assume a value of 4% per day.
The exponential decay is modeled by the following equation:
A = A0*e^(-r*t)
where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).
At half-life A = A0/2, then:
A0/2 = A0*e^(-0.04*t)
0.5 = e^(-0.04*t)
ln(0.5) = -0.04*t
t = ln(0.5)/-0.04
t = 17.33 days
In general the half-life time is:
t = ln(0.5)/-r
Hopefully this helped you.
Answer:
16
Step-by-step explanation:
the proportion pf grape lollipops to all lollipops is 5/30=1/6 so 1/6 of all lollipops are gonna be grape so from 100 lollipops the graoe ones are gonna be 100/6=16.(6) we take only the whole part because we cant have 0.6 of a lollipop
Answer:
The answer should be $20. Hopefully this helps.
