Answer:

18 days

Step-by-step explanation:

Find how many days it can be expected to rain by finding 60 percent of 30

30(0.6)

= 18

STatiana [176]

Answer:

20 e^{k*10} = 60 e^{0.2*10}

We can divide both sides by 20 and we got:

e^{10k}= 3 e^{2}

Now we can appply natural log on both sides and we got:

10 k = ln(3e^2)

Now we can divide both sides of the equation by 10 and we got:

k = \frac{ln(3e^2)}{10}= 0.30986

So then the aproximate value of k is 0.30986 and rounded would be 0.31

Step-by-step explanation:

We have the following two expression:

p_1 = 20 e^{kt}

p_2 = 60 e^{0.2t}

We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:

20 e^{k*10} = 60 e^{0.2*10}

We can divide both sides by 20 and we got:

e^{10k}= 3 e^{2}

Now we can appply natural log on both sides and we got:

10 k = ln(3e^2)

Now we can divide both sides of the equation by 10 and we got:

k = \frac{ln(3e^2)}{10}= 0.30986

So then the aproximate value of k is 0.30986 and rounded would be 0.31
