Answer:

x + 2x

Step-by-step explanation:

x/x^2 can be simplified to x(1/x)

x - x^2 = x(1 - x)

But x + 2x is the same

A 22 gram sample of a substance that's used to preserve fruit and vegetables has a k-value of 0.1011. Find the substance's half-

Eddi Din [679]

<span>Formula for exponential decay is:

N = No * e^-kt

N = 1/2(45) = 22.5

No = 45

k = 0.1109
The solution to your problem is as follows:

Let's try to solve the half-life if it is 45 grams, after which, you will now have an idea on how to solve the problem.

22.5 = 45 * e^(-0.1109t)

1/2 = e^(-0.1109t)

ln(1/2) = -0.1109t

t = (ln(1/2))/(-0.1109) = 6.25 days
