Un faro barre con sy luz un angulo plano de 128°. Si el alcance
maximo del faro es de 15 millas
¿cual es la longitud del arco en
millas correspondientes?

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

15: 24

62.5%

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

answer is  

a.

p = 78
