Find an equation of the tangent line to the curve 2(x2+y2)2=25(x2−y2) (a lemniscate) at the point (−3,1). An equation of the tan

valina [46]

$2(x^2+y^2)^2=25(x^2-y^2)$

Let $y=y(x)$ , so that differentiating both sides wrt $x$ gives

$4(x^2+y^2)\left(2x+2y\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(2x-2y\dfrac{\mathrm dy}{\mathrm dx}\right)$

If $x=-3$ and $y=1$ , the above reduces to

$40\left(-6+2\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(-6-2\dfrac{\mathrm dy}{\mathrm dx}\right)\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac9{13}$

This is the slope of the tangent line, which has equation

$y-1=\dfrac9{13}(x+3)\implies\boxed{y=\dfrac{9x+40}{13}}$

T=mv^2/L<br><br> Write an equation that shows the given formula solved for V

Effectus [21]

Answer:

<u>v = √(LT/m)</u>

Step-by-step explanation:

Given :

T = mv²/L

Multiply both sides with L :

T × L = mv²/L x L
LT = mv²

Divide both sides by m :

LT × 1/m = mv² × 1/m
LT/m = v²

Take the square root on each side :

√v² = √(LT/m)
<u>v = √(LT/m)</u>
