Answer:

Quotient = x^ -1 and the remainder: 0

Step-by-step explanation:

Constant to the left with the opposite sign and coefficients to the right:

-5 | 1 5 -1 -5

Make an horizontal line

Bring down the first coefficient (1) under the line.

Multiply the constant -5 times 1=-5 and add -5 to 5 = 0

Keep doing the same with the coefficients.

Lines l and m intersect so that the measure of ∠1 is 50°. What is the measure of ∠2?

sergeinik [125]

Answer:

Step-by-step explanation:

Without an illustration, I can’t know the position of ∠2 to ∠1.

If the angles are adjacent then ∠2 = 180° - ∠1 = 130°.

Otherwise, ∠2 = ∠1 = 50°

(8 -2i)^2 <br>a:60 <br>b:68-32i <br>c:60-32i <br>d:64-32i+4i^2

AURORKA [14]

Answer:

60-32i

Step-by-step explanation:

(8-2i)^2=8^2-2.8.2i+(2i)^2

=64-32i+4i^2

=64-32i-4

=60-32i

Find the flux of the following vector fields across the given surface with the specified orientation. You may use either an expl

The tetrahedron passes through the intercepts (5, 0, 0), (0, 2, 0), and (0, 0, 10). Parameterize the surface (call it $\Sigma$ ) by

$\vec r(u,v)=(1-v)\langle5,0,0\rangle+v\left((1-u)\langle0,2,0\rangle+u\langle0,0,10\rangle\right)$

$\vec r(u,v)=\langle5(1-v),2(1-u)v,10uv\rangle$

with $0\le u\le1$ and $0\le v\le1$ . Take the normal vector to $\Sigma$ to be

$\vec r_v\times\vec r_u=\langle20v,50v,10v\rangle$

Then the flux of $\vec F(x,y,z)=\langle x,y,z\rangle$ across $\Sigma$ is

$\displaystyle\iint_\Sigma\vec F\cdot\mathrm d\vec S=\int_0^1\int_0^1\langle5(1-v),2(1-u)v,10uv\rangle\cdot\langle20v,50v,10v\rangle\,\mathrm du\,\mathrm dv$

$=\displaystyle\int_0^1\int_0^1100v\,\mathrm du\,\mathrm dv=\boxed{50}$
