consider a quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1). determine the most accurate type of quadrilateral from the
Burka [1]

Answer:

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

Step-by-step explanation:

Considering the quadrilateral with vertices

  • d(0,0)
  • i(5,5)
  • n(8,4)
  • g(7,1)

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

From the figure a, it is clear that the quadrilateral has

  • Two pairs of sides
  • Each pair having two equal-length sides which are adjacent
  • The angles being equal where the two pairs meet
  • Diagonals as shown in dashed lines cross at right angles,  and one of the diagonals does bisect the other - cuts equally in half

Please check the attached figure a.

A ten-inch candle is being burned at both ends. one end burns at the rate of one inch per hour; the other end, one-and-a-half in
Sergio [31]
First keep in mind that the center is 5 inches...let L and R be the left and right positions of the two flames...

L=h and R=10-1.5h  where h is in hours....

The two flames meet when L=R so we can say:

h=10-1.5h  add 1.5h to both sides

2.5h=10  divide both sides by 2.5

h=4

So the flames will meet in five hours, using either original equation we can find this position, I'll use L=h..

L=4

So the position of the flames is 4" from the end.  The questions ask how far this point is from the center so:

5-4=1"

So the flames meet 1 inch from the center.
