Find a general solution of y" - 6y' +10y=0.

babymother [125]

Answer:

$y(x) = e^{3x} [Acos x+Bsin x]$

Step-by-step explanation:

Given is a differential equation

$y" - 6y' +10y=0.$

We have characteristic equation as

$m^2-6m+10 =0$

The above quadratic cannot be factorised hence use formula

$m=\frac{6+/-\sqrt{36-40} }{2} \\=3+i, 3-i$

Hence general solution would be

$y(x) = e^{3x} [Acos x+Bsin x]$

The domain of y=sqrt x-5-1 is

Anastaziya [24]

Answer:

The domain is the interval [5,∞)

Step-by-step explanation:

we have

$y = \sqrt{x-5}-1$

we know that

The radicand (number under a radical) must be greater than or equal to zero

$x-5\geq 0$

solve for x

Adds 5 both sides

$x-5+5\geq 0+5$

$x\geq 5$

therefore

The domain is the interval [5,∞)

All real numbers greater than or equal to 5
