Ratling [72]

Answer:

If two ratios are equivalent to each other, then they are said to be in proportion. For example, the ratios 1:2, 2:4, and 3:6 are equivalent ratios.

Step-by-step explanation:

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

Calculate y as a function of x when dy/dx = 4x3 + 3x2 - 6x + 5
PtichkaEL [24]
Answer:
y = x⁴ + x³ - 3x² + 5x + C

======

Separable differential equations such as these ones can be solved by treating dy/dx as a ratio of differentials. Then move the dx with all the x terms and move the dy with all the y terms. After that, integrate both sides of the equation.

   \begin{aligned}&#10;\dfrac{dy}{dx} &= 4x^3 + 3x^2 - 6x + 5 \\&#10;dy &= (4x^3 + 3x^2 - 6x + 5) dx \\&#10;\int dy &= \int (4x^3 + 3x^2 - 6x + 5) dx &#10;\end{aligned}

In general (understood that +C portions are still there), 

   \int x^{m} = \dfrac{x^{m+1}}{m+1}

Note that ∫dy = y  since it is ∫1·dy = ∫y⁰ dy = y¹/(0+1) = y
For the right-hand side, we use the sum/difference rule for integrals, which says that

   \int \big[f(x) \pm g(x)\big]\, dx = \int f(x)\,dx \pm \int g(x) \, dx

Applying these concepts:

   \begin{aligned} &#10; \int dy &= \int (4x^3 + 3x^2 - 6x + 5) \, dx \\&#10;y &= \int 4x^3\,dx + \int 3x^2 \, dx - \int 6x\, dx + \int 5\, dx \\&#10;&= \frac{4x^4}{4} + \frac{3x^3}{3} - \frac{6x^2}{2} + 5x + C \qquad \text{(only one $C$ is needed)} \\&#10;&= x^4 + x^3 - 3x^2 + 5x + C&#10;\end{aligned}

The answer is y = x⁴ + x³ - 3x² + 5x + C
