Giải các phương trình vi phân sau<br> y' - y/x+1 = 2
KatRina [158]

It looks like the differential equation is

y'-\dfrac y{x+1}=2

Multiply both sides by 1/(<em>x</em> + 1) :

\dfrac{y'}{x+1}-\dfrac y{(x+1)^2} = \dfrac2{x+1}

The left side is now a derivative of a product,

\left(\dfrac y{x+1}\right)' = \dfrac2{x+1}

Integrate both sides with respect to <em>x</em> :

\dfrac y{x+1} = 2\ln|x+1|+C

Solve for <em>y</em> :

y = 2(x+1)\ln|x+1| + C(x+1)

A cafeteria sold 80 frozen yogurts on Monday, and 55% of these were peach yogurt. How many peach yogurts were sold on Monday?
Oliga [24]
The key thing to note is that percentage means that number over 100. Thus 55% can be written as 55/100. This converts to the decimal 0.55. If we then multiply this by 80, we get 44.
44 peach yogurts were sold on Monday.
