Use implicit differentiation to find an equation of the tangent line to the curve at the given point.

andrew11 [14]

Differentiating both sides of

$x^2 + 2xy - y^2 + x = 20$

with respect to $x$ yields

$2x + 2y + 2x \dfrac{dy}{dx} - 2y \dfrac{dy}{dx} + 1 = 0 \\\\ \implies (2x-2y) \dfrac{dy}{dx} = -1 - 2x - 2y \\\\ \implies \dfrac{dy}{dx} = \dfrac{1 + 2x + 2y}{2(y-x)}$

At the point (3, 4) (so $x=3$ and $y=4$ ), the tangent line has slope

$\dfrac{dy}{dx} = \dfrac{1 + 2\times3 + 2\times4}{2(4-3)} = \dfrac{15}2$

Then the tangent line to (3, 4) has equation

$y - 4 = \dfrac{15}2 (x - 3) \implies \boxed{y = \dfrac{15}2 x - \dfrac{37}2}$

The Hawks have won 12 games, which is 60% of the games they have played this season.How many games have the Hawks played this se

loris [4]

Answer:

20 games

Step-by-step explanation:

Let

x ----> total games played this season

we know that

12 games represent 60% of the games they have played this season

using proportion

Find out how many games represent a percentage of 100%

$\frac{12}{60\%}=\frac{x}{100\%}\\\\x=12(100)/60\\\\x=20\ games$
