Answer:

Circumference = 37.68 Ft.

Step-by-step explanation:

Diameter (d) = 12 Ft

Circumference (c) = ?

We know that

C = πd

= 3.14 * 12

= 37.68 Ft.

Hope it will help you :)

The non separable differential equation dy dx = 8x − 2y has a linear particular solution of the form y = mx + b. Find m + b.

yulyashka [42]

Answer:

$m + b=2$

Step-by-step explanation:

From the question we are told that

The non separable differential equation $\frac{dy}{dx} = 8x - 2y$

Generally the chi form of a give equation is mathematically represented as

$\frac{dy}{dx} +P(x)y= q(x)$

$\frac{dy}{dx} + 2y = 8x$

$ye^2^x=\int e^2^.8xdxx$

$ye^2^x=8(\frac{xe^2^x}{2}-\frac{\int e^2^x}{2})$

$ye^2^x=8(\frac{xe^2^x}{2}-\frac{e^2^x}{1})+c\\$

$ye^2^x=4x^2^x-2e^2^x+c$

$y=4x-2+c$

for c=0

$y=4x-2$

Therefore

$m=4\\b=-2\\m + b=4-(+2)$

$m + b=2$

The length of a rectangle solid is 3.0 m the width is 0.6 meter, and the height is 0.4 meter. Find, to the nearest tenth, the nu

Ad libitum [116K]

Answer:

$0.72\,\,m^3$

Step-by-step explanation:

Given:

Length of a rectangle solid = 3 m

Width of a rectangle solid = 0.6 m

Height of a rectangle solid = 0.4 m

To find: Volume of the solid

Solution:

Volume of the solid = length × breadth × height

$=3\times 0.6\times 0.4=0.72\,\,m^3$

So, the number of cubic meters in the volume of the solid is $0.72\,\,m^3$

What is the equation for the line of reflection for ABCD to A’B’C’D’? Explain.

expeople1 [14]

Answer:

$y = \frac{4}{5} x - \frac{1}{5}$

Step-by-step explanation:

calculate midpoint of AA'

calculate midpoint of DD'

A(-5,1)

A'(-1,-3)

D(1,5)

D'(3,1)

then midpoint is

$\frac{x_{d} + x_{d^{1}}}{2} = 2 \\ \frac{y_{d} + y_{d^{1}}}{2} =3 \\ \\ \frac{x_{a} + x_{a^{1}}}{2} = - 3 \\ \frac{y_{a} + y_{a^{1}}}{2} = - 1$

then find slope

$\frac{ y_{2} -y_{1}}{x_{2} -x_{1}} = \frac{4}{5}$

then apply equation

$y = \frac{4}{5} x + b$

substitute any point of the 2 midpoints to find b

$b = \frac{ - 1}{5}$

then the equation is

$y = \frac{4}{5} x - \frac{1}{5} \\$
