A large container holds 5 gallons of water. It begins leaking at a constant rate. After 20 minutes, the container has 3 gallons

jeka57 [31]

The container will take 25 minutes to go from full to empty.

Explanation:

In 15 minutes, the container has lost 3 gallons of water (

−

Since the leak is at a constant rate, we can determine that every five minutes the container loses one gallon.

So for the container to lose the full 5 gallons will take 25 minutes (

Dy/dx = (sin x)/y , y(0) = 2

skad [1K]

Start with

$\dfrac{dy}{dx}=\dfrac{\sin(x)}{y}$

Separate the variables:

$y\;dy = \sin(x)\;dx$

Integrate both parts:

$\displaystyle \int y\;dy = \int\sin(x)\;dx$

Which implies

$\dfrac{y^2}{2} = -\cos(x)+c$

Solving for y:

$y = \sqrt{-2\cos(x)+c}$

Fix the additive constant imposing the condition:

$y(0) = \sqrt{-2+c}=2 \iff -2+c=4 \iff c=6$

So, the solution is

$y(x) = \sqrt{-2\cos(x)+6}$
