The answers to your questions are,

1. Point, Line, and Plane

2. Ray: A ray is like a line, but the line takes off in one direction to infinity while the other side is like a line segment. The end of the line is called the endpoint.

3. They are both containing geometry statements.

4.Say you have an angle of QPR. About 45 degrees.

Place the compass point on the angle's vertex.

Set the compass to ant convenient width.

Draw an arc across each leg.

Compass can be adjusted at this point if desired.

From where the arc crosses a leg, make an arc in the angle's interior.

Without changing the compass width, repeat for the other leg.

Draw a line from Q to where the arcs cross

Done! :)

5. A diameter of the circle is drawn.

A perpendicular bisector of the diameter is drawn using the method described in Perpendicular bisector of a segment. This is also a diameter of the circle.

The resulting four points on the circle are the vertices of the inscribed square.

6.  In a regular hexagon, the side length is equal to the distance from the center to a vertex. In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, equilateral triangles are also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

If (-1,4) and (3,-2) are end points of diameter of the circle, then the equation of the circle is
Volgvan

Answer:

If you've more doubts you can ask :)

Step-by-step explanation:

If the centre of a circle is (a, b) and radius r, then the equation of the circle is :

(x - x)^2 + (y-b)^2 = r^2

<em><u>First we will find the centre, (a , b): </u></em>

<em><u /></em>a = \frac{3+(-1)}{2} = \frac{2}{2} = 1\\\\b = \frac{-2 + 4}{2} = \frac{2}{2} = 1<em><u /></em>

<em><u>Find radius:</u></em>

Radius, r = \frac{Diameter}{2}

Diameter is the distance between (-1, 4) and (3, -2)

diameter = \sqrt{(x_2 - x_1)^2 +(y_2-y_1)^2} \\\\

             = \sqrt{(3-(-1)^2 + (-2-4)^2} \\\\=\sqrt{16 + 36}\\\\=\sqrt{52}\\\\=\sqrt{4 \times 13}\\\\=2\sqrt{13}    \ units

Therefore , r = \frac{2 \times \sqrt{13} }{2} = \sqrt{13}  \ units

<em><u>Equation of the circle is :  </u></em>

                                 (x - 1)^2 +(y-1)^2 = 13<em><u></u></em>

A car travels at 65 miles per hour. Going through collision,it travels at 3/5 this speed. Write this fraction as a decimal.
solniwko [45]

Answer:

0.6

Step-by-step explanation:

the car moves at a speed of 3/5*65 miles per hour

that is 39 miles per hour

but this has nothing to do with the question as the only fraction is 3/5

Draw and shade figures that represent 50%, 25%, and 150%. Label each figure and described it in words. How do I answer this ques
muminat
See photo for drawing. 
Words: 
Suppose a square is 100%, 
50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%. 
25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%. 
150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%.
