Firstly expand it: 50k + 5 + 4 + 16k
Collect like terms: (50k + 16K) + (5 + 4)
Simplify: 66k + 9.

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

BlackZzzverrR [31]

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

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

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

Plz help me with 3 through 5 show ur work

The equation to find the volume of a pyramid is V= $\frac{lwh}{3}$
3.) V= $\frac{3*4 \frac{2}{3} *3 \frac{1}{3} }{3}$ → Multiply the top V= $\frac{46 \frac{2}{3} }{3}$ → Divide by 3 V= $15 \frac{5}{9}$
4.) V= $\frac{2.6*6.4*10.8}{3}$ → Multiply the top V= $\frac{179.712}{3}$ → Divide by 3 V=59.904 or V=59.9
5.) Since you need to find h you put the V value in and keep the h value blank. 1,350= $\frac{15*15*h}{3}$ → 1,350= $\frac{225*h}{3}$ → Multiply 3 by both sides 3×1,350= $\frac{225*h}{3}$ ×3 → 4,050=225×h → Divide 225 from both sides 4,050÷225=225×h÷225 → 18=h

I hope that helps!

A helicopter flies 238 miles in 3 hours 10 minutes. Calculate the average speed.

Alex17521 [72]

Speed equals distance over time, put hours into minutes which is 190 minutes divide that under 238 miles which gives an average of speed of 1.25m/s
