Which is the next step in the following construction of a square?
Sedbober [7]

Answer:

(B)Place compass at point A, and open compass to greater than P.

Step-by-step explanation:

The following steps will be followed in the construction of a Square inscribed in a circle.

  • Draw a circle and label the center P.
  • Draw the diameter of the circle, labeling the endpoints A and B.
  • Construct the perpendicular bisector of the diameter, AB.
  • Label the points where the bisector intersects the circle as C and D.
  • Connect points A to B to C to D to form the square.

Now to construct a perpendicular bisector of AB, the next step is to place the compass at A and open the compass to greater than the center P of the circle. We do the same at point B.

The correct option is B.

You are building a new house on a cartesian plane whose units are measured in miles.
Wewaii [24]
We first find the shortest distance between the point (2, 0) and the curve y=\sqrt{16x^2+5x+16}
Let the point on the curve for which the line making the shortest distance be (x, y), then
d= \sqrt{(x-2)^2+(y-0)^2} = \sqrt{(x-2)^2+y^2}
But, y=\sqrt{16x^2+5x+16}
Therefore,
d=\sqrt{(x-2)^2+(\sqrt{16x^2+5x+16})^2}=\sqrt{x^2-4x+4+16x^2+5x+16}\\= \sqrt{17x^2+x+20}
For minimum d(d)/dx = 0
\frac{d(d)}{dx} = \frac{34x+1}{2 \sqrt{17x^2+x+20}} =0\\34x+1=0\\x=- \frac{1}{34}
Therefore, shortest distance is
d= \sqrt{17(- \frac{1}{34})^2- \frac{1}{34}+20 } = \sqrt{ \frac{1359}{68}} =4.47 \ miles
Since it costs 400 dollars per mile, 4.47 miles will cost 4.47 x 400 = $1,788.20
