area y=5x,y= 1/7 x,y=50-x^2

area

y = 5 x, y = \frac{1}{7} x, y = 50 - x^{2}

\frac{271337}{1029}

Decimal

263.68999 \dots

Solution steps

To find the intersection points solve

f_{i} (x) = f_{j} (x)

5 x = \frac{1}{7} x : x = 0

5 x = 50 - x^{2} : x = - 10, x = 5

\frac{1}{7} x = 50 - x^{2} : x = - \frac{50}{7}, x = 7

= \int_{- 10}^{- \frac{50}{7}} ∣ f_{1} (x) - f_{3} (x) ∣ d x + \int_{- \frac{50}{7}}^{0} ∣ f_{2} (x) - f_{1} (x) ∣ d x + \int_{0}^{5} ∣ f_{1} (x) - f_{2} (x) ∣ d x + \int_{5}^{7} ∣ f_{2} (x) - f_{3} (x) ∣ d x

= \int_{- 10}^{- \frac{50}{7}} 5 x - (50 - x^{2}) d x + \int_{- \frac{50}{7}}^{0} \frac{1}{7} x - 5 x d x + \int_{0}^{5} 5 x - \frac{1}{7} x d x + \int_{5}^{7} \frac{1}{7} x - (50 - x^{2}) d x

\int_{- 10}^{- \frac{50}{7}} 5 x - (50 - x^{2}) d x = \frac{55000}{1029}

\int_{- \frac{50}{7}}^{0} \frac{1}{7} x - 5 x d x = \frac{42500}{343}

\int_{0}^{5} 5 x - \frac{1}{7} x d x = \frac{425}{7}

\int_{5}^{7} \frac{1}{7} x - (50 - x^{2}) d x = \frac{538}{21}

= \frac{55000}{1029} + \frac{42500}{343} + \frac{425}{7} + \frac{538}{21}

Simplify

= \frac{271337}{1029}

\frac{d}{d θ} (sin (θ) + tan (θ))

\int \frac{1}{x ^{2} - 2 x - 8} d x

\frac{\partial}{\partial x} (3 ln (x^{2} + y^{2}))

\int \frac{x ^{3}}{x - 1} d x

(8 - 6 y + e^{- 3 x}) d x - 2 d y = 0
