Answer:

9x-3x-4x=6x+4

2x=6x+4

2x-6x=4

Find all values of m so that the function y = xm is a solution of the given differential equation. (Enter your answers as a comm

blagie [28]

Answer:

m = 6,9

Step-by-step explanation:

We are given that $y = x^m$ is a solution to given differential equation.

$x^2y'' - 14xy' + 54y = 0$

First we 3evaluate the value of:

$y'' = m(m-1)x^{(m-2)}$

$y' = mx^{(m-1)}$

Putting these value in the above differential equation, we get,

$x^2m(m-1)x^{(m-2)} + 14xmx^{(m-1)} + 54x^m = 0$

$x^m[m(m-1) -14m + 54] = 0$

$x^m(m^2 - 15m + 54) = 0$

$(m^2 - 15m + 54) = 0$

$(m-9)(m-6) = 0$

$m = 9,6$

Thus, for m = 9,6 , the function $y = x^m$ is a solution of given differential equation.

12. 150 – 3x = 120 + 2x<br> what does x equal?

PolarNik [594]

150 - 3x = 120 + 2x | +3x
150 = 120 + 5x | -120
30 = 5x | :5
6 = x

Can anyone help?? I don't understand.

Andrews [41]

If the height and base are equal, that simply means that b = h, or h = b

and we know the area is 18 m²

$\bf \textit{area of a triangle}\\\\
A=\cfrac{1}{2}bh\qquad 
\begin{cases}
b=h\\
A=18
\end{cases}\implies 18=\cfrac{1}{2}\cdot h\cdot h\implies 18=\cfrac{h^2}{2}
\\\\\\
36=h^2\implies \sqrt{36}=h$
