Find the equation of the circle: y-intercepts 4 and –8, contain (–12, –8)
laila [671]

Answer:

  (x +6)^2 +(y +2)^2 = 72

Step-by-step explanation:

The given points are vertices of a right triangle. The circle circumscribing that triangle (through all 3 vertices) will have its center at the midpoint of the hypotenuse:

  ((0, 4) +(-12, -8))/2 = (-6, -2)

The equation of a circle with center (h, k) through point (a, b) is ...

  (x -h)^2 +(y -k)^2 = (a -h)^2 +(b -k)^2

For center (-6, -2) and point (0, 4), the equation is ...

  (x +6)^2 +(y +2)^2 = (0+6)^2 +(4 +2)^2

  (x +6)^2 +(y +2)^2 = 72

1) Would this be Mal, Lised Or B'Hon?<br><br> 2) Would it be 1560, 1650 or 1700
Fiesta28 [93]
1) The MST will have 3 connections to Mal, more than any other node.

2) The sum of weights is 250 +3*300 +500 = 1650.
.. (You can rule out 1560 as a choice because no weight ends in 10 or 60. This is simply test-taking savvy, not math.)

an aeroplane is flying with a help of 300 km per hour who much distance will it cover in 160 minute ​
uysha [10]

Answer:

800 km

Step-by-step explanation:

Does the plane have a speed of it's own?  I don't see it, so will assume the plane is simply travelling at 300 km/h.

(300 km/hr)*(1 hr/60 min) = 5 km/min

(5 km/min)*(160 min) = 800 km in 160 minutes
