Evaluate the surface integral. s x ds, s is the part of the plane 6x + 3y + z = 6 that lies in the first octant.
Musya8 [376]
The plane has intercepts at (1, 0, 0), (0, 2, 0), and (0, 0, 6), so we can parameterize the surface \mathcal S by

\mathbf r(u,v)=((1,0,0)(1-u)+(0,2,0)u)(1-v)+(0,0,6)v
\mathbf r(u,v)=((1-u)(1-v),2u(1-v),6v)

where 0\le u\le1 and 0\le v\le1. Now

\|\mathbf r_u\times\mathbf r_v\|=2\sqrt{46}(1-v)

so the surface integral reduces to

\displaystyle\iint_{\mathcal S}x\,\mathrm dS=2\sqrt{46}\int_{v=0}^{v=1}\int_{u=0}^{u=1}(1-u)(1-v)^2\,\mathrm du\,\mathrm dv=\frac{\sqrt{46}}3

PLS HELP<br><br> heres my question i pinned as a picture
Murrr4er [49]

Advanced ($10): A

Door ($13): D

Money:      10A + 13D = 544  ⇒  1(10A + 13D = 544)   ⇒   10A + 13D =  544

Quantity:      A  +    D =  46   ⇒ -10(A   +    D =  46)    ⇒  <u> -10A - 10D</u> = <u>-460 </u>

                                                                                                       3D =    84

                                                                                                         D =    28

Quantity: A + D = 46   ⇒   A + (28) = 46   ⇒   A = 18

Answer: advanced = 18 people, at the door = 28 people
