Solve for C when 9=c(c-8)<br><br> Can you show your work too? This question confuses me!
Marrrta [24]
9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9

In short, Your Answers would be -1 and 9

Hope this helps!

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
