We know that

<span>the rotation of a solid does not modify the values of the internal angles of the solid
</span>therefore
interior angle after 90° rotation=interior angle before 90° rotation
interior angle after 90° rotation=108°

What is the volume of a cube with length 4 inches? V=lwh

Nata [24]

The answer is: "64 cubic inches" ; or, write as: "64 in³ " .
_______________________________________________________
Explanation:

V = L * w * h ;

= (4 inches) * (4 inches) * (4 inches) ;

(since a "cube" has the same length, width, and height)

= (4*4*4) inches * inches * inches) ;

= 16 * 4 * inches³ ;

= 64 inches³ ; or, write as: "64 in³ " ; or, write as: "64 cubic inches" .

A polling organization is asking a sample of U.S. Adults how many pets they own. The frequency distribution below shows the resu

fiasKO [112]

Answer:

The probability that the next person asked has two pets is 0.176

Step-by-step explanation:

The given parameters are;

The frequency distribution of the number of pets owned is presented as follows;

Number of Times ${}$ Frequency ${}$

None ${}$ 354

One ${}$ 981

Two ${}$ 352

Three ${}$ 200

Four ${}$ 113

The probability that the next person asked has two pets = Proportion of the sample that own two pets = 352/(354 + 981 + 352 + 200 + 113) = 0.176

Therefore, the probability that the next person asked has two pets = 0.176

Using Euler’s Method with a step size of h=0.5, estimate the value for y(3) for the differential equation xy dy/dx= 1+ln(x^2), w

lora16 [44]

Euler's method uses the recurrence relation

$y_{n+1}=y_n+hf(x_n,y_n)$

to approximate the value of the solution $y(x)$ to the ODE $y'=f(x,y)$ .

$xy\dfrac{\mathrm dy}{\mathrm dx}=1+\ln(x^2)\implies y'=\dfrac{1+\ln(x^2)}{xy}=f(x,y)$

With a step size of $h=0.5$ , there will only be two steps necessary to find the approximate value of $y(3)$ based on the initial point $y(2)=5$ . See the attached table below for the computation results.

To demonstrate how the table is generated: Since $y(2)=5$ , you are using $(x_0,y_0)=(2,5)$ .

$y_1=y_0+hf(x_0,y_0)$
$y_1=5+0.5\times\dfrac{1+\ln(2^2)}{2\times5}$
$y_1\approx5.1193$

The next point then uses $x_1=x_0+0.5=2.5$

$y_2=y_1+hf(x_1,y_1)$
$y_1=y_1+0.5\times\dfrac{1+\ln(2.5^2)}{2.5y_1}$
$y_2\approx5.230$
