Consider the differential equation: xy′(x2+7)y=cos(x)+e3xy. Put the differential equation into the form: y′+p(x)y=g(x), determin

icang [17]

Answer:

Linear and non-homogeneous.

Step-by-step explanation:

We are given that

$\frac{xy'}{(x^2+7)y}=cosx+\frac{e^{3x}}{y}$

We have to convert into y'+P(x)y=g(x) and determine P(x) and g(x).

We have also find type of differential equation.

$y'=\frac{(x^2+7)y}{x}(cosx+\frac{e^{3x}}{y}}$

$y'=\frac{(x^2+7)cosx}{x}y+\frac{(x^2+7)e^{3x}}{x}$

$y'-\frac{cosx(x^2+7)}{x}y=\frac{e^{3x}(x^2+7)}{x}$

It is linear differential equation because this equation is of the form

y'+P(x)y=g(x)

Compare it with first order first degree linear differential equation

$y'+P(x)y=g(x)$

$P(x)=-\frac{cosx (x^2+7)}{x},g(x)=\frac{e^{3x}(x^2+7)}{x}$

$\frac{dy}{dx}=\frac{(x^2+7)(ycosx+e^{3x})}{x}$

Homogeneous equation

$\frac{dy}{dx}=\frac{f(x,y)}{g(x,y)}$

Degree of f and g are same.

$f(x,y)=(x^2+7)(ycosx+e^{3x}),g(x,y)=x$

Degree of f and g are not same .

Therefore, it is non- homogeneous .

Linear and non-homogeneous.

Find each measure.<br> m1, m2, m3

lyudmila [28]

Answer:

second option

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

∠ 1 and 33° form a straight angle and are supplementary, thus

∠ 1 = 180° - 33° = 147°

----------------------------------

The third angle in the triangle on the left is

180° - (33 + 47)° = 180° - 80° = 100°, thus

∠ 2 = 180° - 100° = 80°

--------------------------------------

∠ 2 and the angle in the triangle form a straight angle and are supplementary,

angle = 180° - 80° = 100°

The third angle in the triangle on the right is

180° - (100 + 48)° = 180° - 148° = 32°, thus

∠ 3 = 180° - 32° = 148° ( straight angle )

Thus

∠ 1 = 147°, ∠ 2 = 80°, ∠ 3 = 148°

Which transformations have been performed on the graph of f(x) =<img src="https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D" id="Tex

Nookie1986 [14]

Answer:

(B) compress the graph closer to the x-axis

(E) translate the graph to the left

(F) translate the graph up

Step-by-step explanation:

When functions are transformed there are a few simple rules:

Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
Multiplying the function by a number less than 1 compresses it towards the x-axis.
Multiplying the function by a number greater than 1 stretches it away from the x-axis.

This graph has been multiplied by 1/4 which is less than 1. It will be compressed.

This graph has x added to by 3. It will shift left 3 units.

This graph has the output outside of x added to by 6. It will shift 6 units up. See picture below. The original function is red. The new function is blue.

the backyard of a new home is shaped like a trapezoid with a height of 42 ft and bases of 88 ft and 111 ft. what is the cost of

alina1380 [7]

I think it’s pretty interpretative, the reason I didn’t divide 483/2 like you would normally with a triangle, is because there are 2 triangles in a trapezoid. Also you can split the two triangles off the trapezoid because in a trapezoid the train for will awkward be right.
