Answer:

$y=\sqrt{\frac{x^4-6x^2+12x+c_1}{2}},\:y=-\sqrt{\frac{x^4-6x^2+12x+c_1}{2}}$

(Please vote me Brainliest if this helped!)

Step-by-step explanation:

$\frac{dy}{dx}y=x^3+2x-5x+3$

$\mathrm{First\:order\:separable\:Ordinary\:Differential\:Equation}$

$\mathrm{A\:first\:order\:separable\:ODE\:has\:the\:form\:of}\:N\left(y\right)\cdot y'=M\left(x\right)$

1. $\mathrm{Substitute\quad }\frac{dy}{dx}\mathrm{\:with\:}y'\:$

$y'\:y=x^3+2x-5x+3$

2. $\mathrm{Rewrite\:in\:the\:form\:of\:a\:first\:order\:separable\:ODE}$

$yy'\:=x^3-3x+3$

$N\left(y\right)\cdot y'\:=M\left(x\right)$

$N\left(y\right)=y,\:\quad M\left(x\right)=x^3-3x+3$

3. $\mathrm{Solve\:}\:yy'\:=x^3-3x+3:\quad \frac{y^2}{2}=\frac{x^4}{4}-\frac{3x^2}{2}+3x+c_1$

4. $\mathrm{Isolate}\:y:\quad y=\sqrt{\frac{x^4-6x^2+12x+4c_1}{2}},\:y=-\sqrt{\frac{x^4-6x^2+12x+4c_1}{2}}$

5. $\mathrm{Simplify}$

$y=\sqrt{\frac{x^4-6x^2+12x+c_1}{2}},\:y=-\sqrt{\frac{x^4-6x^2+12x+c_1}{2}}$

Liz needs to keep no less than $500 in her checking account to avoid fees. She had $524.75 before writing a check for $65.99. Ho

geniusboy [140]

Answer: $41.24

Step-by-step explanation: In order to figure out how much she is away from 500 we need to first subtract the 65.99.

524.75 - 65.99 = 458.76

Then find the difference from 500 by subtracting again.

500 - 458.76 = 41.24

41.24 is the amount she needs to deposit in order to avoid a fee.

What index of m will be 1/m

Mashcka [7]

Answer:

-1.

Step-by-step explanation:

1/m = m^-1.

We can show this is correct if we simplify the following:

m^2 / m ^3 = m * m / m * m* m = 1/m

By the law of indices: m ^2 / m^3 = m^(2-3) = m^-1.
