Answer:

False.

Step-by-step explanation:

Independent variable values go on the x axis, not the y axis.

Answer: true

Step-by-step explanation:

When doing experiments the factor that will change will go on the y axis. The variables that will never change will go on the x axis.

So variables such as time and dates will be on the X axis because they will never change.

Variables such as money, and anything else that will change will go on the y axis.

Something that helped me to remember this was that if you were going to build a house and use the letters X or Y as your base, what would you choose?

Hopefully it would be the X, because unlike the letter Y the X will not tilt to one side or the other. X will never change, unlike Y.

Solve the given differential equation by using an appropriate substitution. The DE is a Bernoulli equation.

Mama L [17]

Multiplying both sides by $y^2$ gives

$xy^2\dfrac{\mathrm dy}{\mathrm dx}+y^3=1$

so that substituting $v=y^3$ and hence $\frac{\mathrm dv}{\mathrm dv}=3y^2\frac{\mathrm dy}{\mathrm dx}$ gives the linear ODE,

$\dfrac x3\dfrac{\mathrm dv}{\mathrm dx}+v=1$

Now multiply both sides by $3x^2$ to get

$x^3\dfrac{\mathrm dv}{\mathrm dx}+3x^2v=3x^2$

so that the left side condenses into the derivative of a product.

$\dfrac{\mathrm d}{\mathrm dx}[x^3v]=3x^2$

Integrate both sides, then solve for $v$ , then for $y$ :

$x^3v=\displaystyle\int3x^2\,\mathrm dx$

$x^3v=x^3+C$

$v=1+\dfrac C{x^3}$

$y^3=1+\dfrac C{x^3}$

$\boxed{y=\sqrt[3]{1+\dfrac C{x^3}}}$

5 out of nine students in the sophomore class in musicians if there are 450 students in the sophomore class for many of them are

Anarel [89]

Answer:

250 Students are musicians, 200 are not.

Step-by-step explanation:

Decimal Version:

If we take "5 out of every nine students are musicians" and make this a fraction we get 5/9. 5/9 as a decimal is approximately 55.555555555556. 55.555555555556% of 450 = 250. So that means 250 students are musicians.
