You do:
X*x(x^2)
X*-5
X*-5
Then -5*-5
Put it together and you get

Find the slope of tangent line at (1,-1.5)

storchak [24]

Answer:

The slope of the tangent m = -0.0833

Step-by-step explanation:

Step(i):-

Given that the curve

x y - 2y² + x² = -5 ...(i)

Differentiating equation (i) with respective to 'x', we get

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

$x(\frac{dy}{dx} ) -2(2y)\frac{dy}{dx} = -2x-y$

$(x -4y)\frac{dy}{dx} = -2x-y$

$\frac{dy}{dx} = \frac{-2x-y}{x-4y}$

Step(ii):-

The slope of the tangent

$(\frac{dy}{dx})_{1,-1.5} = \frac{-2x-y}{x-4y}$

$(\frac{dy}{dx})_{1,-1.5} = \frac{-2(1)-(-1.5)}{1-4(-1.5)}$

m = $\frac{-2+1.5}{1+6}$

$m = \frac{-0.5}{6} = -0.083$

The slope of the tangent m = -0.0833

Step-by-step explanation:

Each number in the series is greater than the previous number by 4.

(n/2) * (S + (S + ((n-1) * 4)))

where:

S = 7

n = 26

(26/2)× (7+(7+((26-1) ×4)))

(13)× (7+(7+(25)×4)

13×114
