Point A has the coordinates (6, –4). On a coordinate plane, point R is 6 units to the left and 4 units up. Point S is 6 units to

the right and 4 units down. Point T is 6 units to the left and 4 units down. Point U is 6 units to the right and 4 units up. Which point on the graph shows the reflection of point A across the y-axis? R S T U

Answer:

The point T shows the reflection of point A across the y-axis

Step-by-step explanation:

we know that

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite

so

The reflection of a point across the y-axis is equal to the rule

(x,y) -----> (-x,y)

we have

A(6,-4)

Applying the reflection across the y-axis to point A

A(6,-4) -----> A'(-6,-4)

Remember that

Point T is 6 units to the left and 4 units down

therefore

The point T shows the reflection of point A across the y-axis

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.
liberstina [14]

Correct answer is A.

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

<h3>How to calculate the diameter?</h3>

If you know the radius of the circle, multiply by 2 to get the diameter. The radius is the distance from the center of the circle to the edge. For example, if the radius of a circle is 4 cm, then the diameter is 4 cm x 2 = 8 cm. If you know the circumference of the circle, divide by π to get the diameter.

<h3>Briefing:</h3>

The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction which is A.

The diameter of the circle is used for the square as l=2r therefore corresponds to the diameter, while for a hexagon r=r being the radius of the circle.

I understand that the question you are looking for is:

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.

A) The diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.

B) The radius of the circle is used for the square construction, but the diameter of the circle is used for the regular hexagon construction.

C) The square will need two arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

D) The square will need six arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.
