distance (-1,8),(4,-2)

Solution

distance

(- 1, 8), (4, - 2)

55

étapes des solutions

Calculer la distance entre

(x_{1}, y_{1}), (x_{2}, y_{2})

(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}

La distance entre

(- 1, 8)

(4, - 2)

est

= (4 - (- 1))^{2} + (- 2 - 8)^{2}

Simplifier

= 55

2 csc (\frac{1}{3} (x - 1)) - 2

f (x) = \frac{3 x - 15}{x ^{2} - 25}

f (x) = x^{2} + 5 x

f (x) = \frac{1}{x} - 1

f (x) = 5 + 4 x - x^{2}
