Summarize the water cycle

Dafna11 [192]

Answer:

<em><u>The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.</u></em>

Using a geometric growth model to predict population growth, a population of 10 individuals at time zero with a finite growth ra

Grace [21]

Answer: Option E, in 12 years.

Explanation:

A geometric growth model is characterized by its finite growth rate, known as lambda. The size of the population after a unit of time has passed can be calculated using the last known size and lamba as:

$N_{t+1} = \lambda * N_t$

Starting from the initial value of population, the next one will be calculated multiplying by 1.4, and the next one multiplying again by 1.4, thus we can define a function that relates the time passed in year to the size of the population:

$N(t) = \lambda^{t} *N_0$

Substituting our values we get the function that defines the growth of our poupulation:

$N(t) = 1.4^{t} *10$

Then, we just have to clear the t that gives a population of 500:

$500 = 1.4^t*10, divide\ both\ sides\ by\ 10\\50 = 1.4^t, apply\ log_{1.4}(x)\ to\ both\ sides\\log_{1.4}(50)=t\\11.63=t$

Thus, at 12 years, the population will be greater than 500.
