the population of a town increases at a rate proportional to its population with an initial population of 1000. The corect initi

anyanavicka [17]

Answer:

This means that the correct initial value problem for the population p(t) as a function of time is is $P(0) = 1000$

Step-by-step explanation:

The population of a town increases at a rate proportional to its population:

This means that this situation is modeled by the following differential equation:

$\frac{dP}{dt} = kP$

In which k is the growth rate.

By separation of variables, the solution is given by:

$P(t) = P(0)e^{kt}$

In which P(0) is the initial population.

Initial population of 1000.

This means that the correct initial value problem for the population p(t) as a function of time is is $P(0) = 1000$

The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to

Morgarella [4.7K]

Answer:

9 mph

Step-by-step explanation:

Let he speed of the boat on the lake is x.

<u>Considering the speed of the current it will take him:</u>

22.5/(x + 6) + 22.5/(x - 6) = 9
2.5 / (x + 6) + 2.5 / (x - 6) = 1
2.5(x - 6 + x + 6) = (x + 6)(x - 6)
2.5*2x = x² - 36
x² - 5x - 36 = 0
x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
