Answer: $\frac{19}{20} - \frac{10}{20} - \frac{2}{20}$

$\frac{7}{20}$

Step-by-step explanation:

Since the Least Common Denominator is 20 (or the biggest number on the bottom in your case), you can multiply 4 and 10 by their corresponding number to get 20.

4 * 5 = 20

10 * 2 = 20

Now multiply the top and bottom by 5 and 2

$\frac{5}{5} *\frac{2}{4}$ = $\frac{10}{20}[tex]\frac{2}{2} *\frac{1}{10}$ = $\frac{2}{20}Now subtract everything.[tex]\frac{19}{20} - \frac{10}{20} - \frac{2}{20}$

Its equals $\frac{7}{20}$ .

Answer:

You do it, or ask someone

Step-by-step explanation:

Because. Just because. That's logic.

jk.... 19/20 - 10/20 - 2/20

19/20 - 12/20

7/20

Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol

Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.

Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:

$345(1.30)^4 = \boxed{985.35}$

Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.

Solve the given initial-value problem. (x + y)2 dx + (2xy + x2 − 2) dy = 0, y(1) = 1

Yuri [45]

Let's check if the ODE is exact. To do that, we want to show that if

$\underbrace{(x+y)^2}_M\,\mathrm dx+\underbrace{(2xy+x^2-2)}_N\,\mathrm dy=0$

then $M_y=N_x$ . We have

$M_y=2(x+y)$
$N_x=2y+2x=2(x+y)$

so the equation is indeed exact. We're looking for a solution of the form $\Psi(x,y)=C$ . Computing the total differential yields the original ODE,

$\mathrm d\Psi=\Psi_x\,\mathrm dx+\Psi_y\,\mathrm dy=0$
$\implies\begin{cases}\Psi_x=(x+y)^2\\\Psi_y=2xy+x^2-2\end{cases}$

Integrate both sides of the first PDE with respect to $x$ ; then

$\displaystyle\int\Psi_x\,\mathrm dx=\int(x+y)^2\,\mathrm dx\implies\Psi(x,y)=\dfrac{(x+y)^3}3+f(y)$

where $f(y)$ is a function of $y$ alone. Differentiate this with respect to $y$ so that

$\Psi_y=2xy+x^2-2=(x+y)^2+f'(y)$
$\implies2xy+x^2-2=x^2+2xy+y^2+f'(y)$
$f'(y)=-2-y^2\implies f(y)=-2y-\dfrac{y^3}3+C$

So the solution to this ODE is

$\Psi(x,y)=\dfrac{(x+y)^3}3-2y-\dfrac{y^3}3+C=C$

i.e.

$\dfrac{(x+y)^3}3-2y-\dfrac{y^3}3=C$
