The sum of a number w and 3 is less than or equal to ten.

Assoli18 [71]

W + 3 ≤ 10

This is the symbol for less than or equal ≤

w + 3 ≤ 10

w ≤ 10 - 3

w ≤ 7

Can't find an answer for w from the options.

11-16

Answer:

See below in bold.

Step-by-step explanation:

To do these we add or subtract 360 degrees or 2 pi radians. Sometimes multiple actions are required.

11. Adding 360 to -545:

= -185

185 + 360 = 175

The other angle is 185 degrees so they are not coterminal.

12. 161pi/36 - 2pi

= 161pi /36 - 72pi/36

= 89pi/36

89pi/36 - 72pi/36

= 17pi/36.

So these are coterminal.

13. -330 + 360 = 30 degrees.

14. -435 + 360

= -75

-75 + 360

= 285 degrees

15. 640 - 360 = 280 degrees.

16. -442 + 360 = -82

-82 + 360 = 278 degrees.

Evaluate the given integral by making an appropriate change of variables. 10 x ? 5y 8x ? y da, r where r is the parallelogram en

Artyom0805 [142]

Take

$\begin{cases}u=x-5y\\v=8x-y\end{cases}$

so that you have

$\begin{cases}\mathbf x(u,v)=\dfrac{-u+5v}{39}\\\\\mathbf y(u,v)=\dfrac{-8u+v}{39}\end{cases}$

which gives a Jacobian determinant of

$|\det J|=\left|\begin{vmatrix}\mathbf x_u&\mathbf x_v\\\mathbf y_u&\mathbf y_v\end{vmatrix}\right|=\dfrac1{32}$

So upon transforming the coordinates to the u-v plane, you have (and I'm guessing on what the integrand actually is)

$\displaystyle\iint_R(10x-5y)(8x-y)\,\mathrm dA=\frac1{32}\int_{u=0}^{u=2}\int_{v=5}^{v=10}\frac5{13}(2u+3v)v\,\mathrm dv\,\mathrm du$
$=\displaystyle\frac5{416}\int_{u=0}^{u=2}\int_{v=5}^{v=10}(2uv+3v^2)\,\mathrm dv\,\mathrm du=\dfrac{2375}{104}$
