Situation: a 25 gram sample of a substance that’s used for drug research has a K-value of 0.1205
Lelu [443]
The decay model is given as

N=N_0e^{-Kt}

The substance's half-life is the time it takes for the substance to decay to half its original amount. In other words, it's the time t such that N=\dfrac{N_0}2. Substituting into the model, you have

\dfrac12=e^{-Kt}

You can solve for t now.

\dfrac12=e^{-Kt}
\implies\ln\dfrac12=\ln e^{-Kt}
\implies-\ln2=-Kt\ln e
\implies\dfrac{\ln2}K=t\approx5.7523\text{ days}

Can someone help me with this??
dusya [7]

Answer:

Carlos and Pamela drove 120 miles on the first day, 240 miles on the second day, and 290 miles on the third day.

Step-by-step explanation:

Let x be the number of miles driven on the first day.

Then they drove twice as many miles, or 2x on the second day

and 50 miles more than the second day's, so 2x + 50

The total is 650 across all three days, so we'll take the sum.

x + 2x + (2x + 50) = 650

Combine like terms on the left

5x + 50 = 650

Subtract 50 on both sides

5x = 600

Divide by 5 on both sides

x = 120

Check work:

120 + 2(120) + 2(120) + 50 = 650

120 + 240 + 240 + 50 = 650

600 + 50 = 650

650 = 650

So they drove 120 miles on the first day

2*120 = 240 miles on the second day

and 2*120 + 50 = 240 + 50 = 290 miles on the third day
