Kisachek [45]

Answer:

x < 15

Step-by-step explanation:

\frac{x}{5} - 3 < 0 ( add 3 to both sides )

\frac{x}{5} < 3 ( multiply both sides by 5 to clear the fraction )

x < 15

An angle whose measure is _____ is rotated more than halfway around a circle
zaharov [31]

The correct answer is 60⁰.

Step-by-step explanation:

  • An angle whose measure is 60⁰ is rotated more than halfway around a circle.
  • Since, we have to find the measure of angle.  
  • As we already know that the angle of rotation about a circle is 360° therefore we have to find more than halfway of this angle.
  • Considering that an angle is rotated more than halfway around a circle be \frac{1}{6}
  • Multiplying \frac{1}{6} with 360⁰
  • Therefore, it can show as \frac{1}{6}×360⁰
  • Which gives the result to be 60⁰
  • Hence, when an angle is measured 60⁰, it is rotating more than halfway around a circle.
  • A single rotation around a circle is equal to 360 degrees.
  • The measurement of an angle shows the magnitude and direction of the rotation of the angle from its initial position to the final position.
  • If the rotation is in a counterclockwise direction, it has an angle with positive measure. If the rotation is clockwise, it has an angle which gives negative measure.

Describe in words the region of R3 reperesented by the equations or inequalities y2+z2=16
Anastasy [175]

Answer:

It represents an infinite cylinder of radius 4.

Step-by-step explanation:

The first thing to notice is that

y^2+z^2=4^2

<u>represents a circle of radius 4</u>, with its center in the origin of a plane yz, of cartesians coordinates.

Starting from here, we have to put the coordinate x, for all values of x, to complete the space R³. <em>This will enlarge this circle we had on the plane, to infinity</em> (positive and negative on the x-axis).

Finally, we have that this region is a cylinder of radius 4, with center in y=0 and z=0, and of infinite length in the x coordinates.
