Which statement will accurately correct the two-column proof? the measure of angle zry equals 180° by definition of supplementar

y angles. Angles qry and pqr should be proven congruent after the construction of line zy. The three angles of δpqr equal 180° according to the transitive property of equality. Line zy should be drawn parallel to segment qr.

There are different kinds of angles. The statement that will accurately correct the two-column proof is that the definition of angle on a straight line.

<h3>What is straight angle? </h3>
  • This is an angle whose sides sit in opposite directions from the vertex  usually in the same straight line and is said to be equals two right angles.

Two angles are known to be supplementary when their measures if sum up reaches  180 degrees.

Conclusively, Looking at the angle, m∠ZRY = 180°, this is because angle ZRY is a straight angle and it is not a supplementary angle.

Therefore option A is the correct answer (Image attached)

An ice skater has a moment of inertia of 5. 0 kg∙m2 when her arms are outstretched. At this time she is spinning at 3. 0 revolut
Sindrei [870]

Answer:

2440.24 J

Explanation:

Moment of inertia, I1 = 5 kg m^2

frequency, f1 = 3 rps

ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s

Moment of inertia, I2 = 2 kg m^2

Let the new frequency is f2.

ω2 = 2 x π x f2

here no external torque is applied, so the angular momentum remains constant.

I1 x ω1 = I2 x ω2

5 x 6 π = 2 x 2 x π x f2

f2 = 7.5 rps

ω2 = 2 x π x 7.5 = 15 π

Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J

Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J

Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J

Compare the measures. describe what these measures indicate about the shape of the box-and-whisker plot
olasank [31]

The measures give the description of the shape and the whisker plot from the data.  The median is always placed in the middle of the center.

<h3>What is a graph?</h3>

A graph is the diagrammatical representation of the data or information set that are illustrated in the form of vertical and horizontal coordinates.

The data given shows:

  • Mean = 39,500
  • Median = 20000
  • Mode = 23000
  • Minimum = 15,000
  • Maximum = 255000

The whisker plot and the box shape are attached as an image below.

From the image, it can be seen that whiskers are at the right and left of the box, and the box initiates from the lower quartile to the upper quartile.

The median of the data is at the middle, the maximum is at the end of the right whisker, and the minimum is at the end of the left whisker.
