Find the measure of an angle between 0º and 360º coterminal with an angle of –110º in standard position
kondor19780726 [428]
<h2>Answer:</h2>

An angle measures how how much you have to rotate one line called <em>initial side</em> so it lies on the top of other line called the <em>terminal side. </em>Angles whose vertex is located at the origin having the initial side on the positive x-axis is said to be in standard position. On the other hand, coterminal angles are angles in standard position having the same terminal side. In this way, for the angle:

-110^{\circ} \\ \\ Its \ coterminal \ is: \\ \\ \alpha=360^{\circ}-110^{\circ}=\boxed{250^{\circ}}

A quadratic equation has a
11111nata11111 [884]

Answer:

\boxed {\boxed {\sf 2 \ real \ solutions }}

Step-by-step explanation:

The quadratic formula is:

{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}

The discriminant of a quadratic is just the expression under the square root, or b^2-4ac. This can tell us the number of solutions a quadratic has.

If the discriminant is:

  • Positive = 2 real solutions
  • Equal to Zero = 1 real double/repeated solution
  • Negative = 0 real solutions, but 2 imaginary solutions

Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.
