y = {x}^{3}  - 4 {x}^{2}  - 45x \\ y = x( {x}^{2}  - 4x - 45) \\ y = x(x + 5)(x - 9) \\ x = 0, - 5,9
So, to find our x-intercepts, y must be zero
0 = x \\  \\ 0 = (x + 5) \\  - 5 = x \\  \\ 0 = (x - 9) \\ 9 = x
ANSWER: (0,0) (-5.0) (9,0) are your x-intercepts

Zina [86]

Answer:

[1] x² - 4/2x - 4

  • 3² - 4/2 × 3 - 4 = 9 - 4/2
  • 5/2

[2] 4 - 3x/2x + 4

  • 4 - 3 × 2/2 × 2 + 4 = 2/8
  • 1/4

[3] x²/2x² - 2

  • 0²/2 × 0² - 2
  • 0

[4] x² + 5/5 - x

  • - 2² + 5/5 + 2 = 4 + 5/7
  • 9/7

[5] - x³/x² - 4

  • - 1³/-1² - 4 = - 1/1 - 4
  • 1/3

[6] x + 3/x³ - 1

  • - 3 + 3/- 3³ - 1 = 0/- 27 - 1
  • 0

[7] 5 - x²/3x²

  • 5 - (- 4)²/3 × - 4² = 5 - 16/3 × 16
  • - 11/48

[8] - 2x + 6/2x³ - 3

  • - 2 × - 2 + 6/2 × - 2³ - 3
  • 10/- 19

[9] 4x²/- 3x² + 1

  • 4 × 1²/- 3 × 1² + 1 = 4/- 2
  • - 2

[10] 4x - 1/6x + 1

  • 4 × 3 - 1/6 × 3 + 1
  • 11/19

[11] x² - 1/x² + 1

  • 1² - 1/1² + 1 = 0/2
  • 0

On a unit circle, the terminal point of 0 is (sqrt3/2,1/2)<br><br> What is 0?
san4es73 [151]

Answer:

The measure of \theta is 30°.

Step-by-step explanation:

In the statement, the angle has been misrepresented. The corrected statement is described below:

<em>"On a unit circle, the terminal point of </em>\theta<em> is </em>\left(\frac{\sqrt{3}}{2}, \frac{1}{2}  \right)<em>. What is </em>\theta<em>?"</em>

The measure of the angle (\theta), in radians, is in standard form, that is, it is done with respect to the +x semiaxis. The measure of the angle whose terminal point is of the form (x,y) is determined by the following inverse trigonometric function:

\theta = \tan^{-1}\left(\frac{y}{x} \right) (1)

If we know that x = \frac{\sqrt{3}}{2} and y = \frac{1}{2}, then the measure of \theta is:

\theta = \tan^{-1} \frac{\sqrt{3}}{3}

\theta = 30^{\circ}

The measure of \theta is 30°.
