Write an equation for the line that is parallel to the glven line and that passes

Wewaii [24]

Answer:

The answer to your question is y = x - 23

Step-by-step explanation:

Process

1.- Get the slope of the line

If two lines are parallels, it means that they have the same slope.

y = 1x - 10

Slope = m = 1

2.- Get the equation of the line

y - y1 = m(x - x1)

y + 29 = 1(x + 6) Substitution

y + 29 = x + 6 Expanding

y = x + 6 - 29 Simplifying

y = x - 23

The velocity v of blood that flows in a blood vessel with radius r and length ℓ at a distance r from the central axis is v(r) =

pogonyaev

$v(r)=4P\eta\ell(R^2-r^2)$

(assuming $R$ is the radius of the vessel, and that $0\le r\le R$ )

The average velocity of the blood is given by

$\displaystyle\frac1{R-0}\int_{r=0}^{r=R}v(r)\,\mathrm dr$
$=\displaystyle\frac{4P\eta\ell}R\int_{r=0}^{r=R}(R^2-r^2)\,\mathrm dr$
$=\dfrac{4P\eta\ell}R\left(\dfrac23R^3\right)$
$=\dfrac{8P\eta\ell}3R^2$
