Yuri [45]

Answers

1) 4

2) 0, 2, -10

3) 0, 5, -2

Step-by-step explanation:

1) x³ - 64 = 0

x³ = 64

x = 4

2) x³(x² + 8x - 20) = 0

x³(x² + 10x - 2x - 20) = 0

x³(x(x + 10) - 2(x + 10)) = 0

x³(x + 10)(x - 2) = 0

x = 0, 2, -10

3) x³ - 3x² - 10x = 0

x(x² - 3x - 10) = 0

x(x² - 5x + 2x - 10) = 0

x(x(x - 5) + 2(x - 5)) = 0

x(x - 5)(x + 2) = 0

x = 0, 5, -2

Use a half-angle identity to find the exact value of sinPi/8
stellarik [79]

Answer:

  sin(π/8) = (1/2)√(2-√2)

Step-by-step explanation:

Using the half-angle formula ...

  \sin{\dfrac{\theta}{2}}=\sqrt{\dfrac{1-\cos{\theta}}{2}}

We can let θ = π/4 and simplify the result as follows:

  \sin{\dfrac{\pi}{8}}=\sqrt{\dfrac{1-\cos{(\pi/4)}}{2}}=\sqrt{\dfrac{1-\dfrac{\sqrt{2}}{2}}{2}}=\sqrt{\dfrac{2-\sqrt{2}}{4}}\\\\=\boxed{\dfrac{1}{2}\sqrt{2-\sqrt{2}}}}

0.2x + 1 = 1.6x + 3.1<br> What value of x satisfies the equation above?
guapka [62]

Answer:

x = -1.5

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

0.2x + 1 = 1.6x + 3.1

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 0.2x on both sides:          1 = 1.4x + 3.1
  2. Subtract 3.1 on both sides:             -2.1 = 1.4x
  3. Divide both sides by 1.4:                 -1.5 = x
  4. Rewrite:                                            x = -1.5

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitution:                    0.2(-1.5) + 1 = 1.6(-1.5) + 3.1
  2. Multiply:                           -0.3 + 1 = -2.4 + 3.1
  3. Add:                                 0.7 = 0.7

Help! The measure of the exterior angle of the triangle is???
just olya [345]

Answer:

92°

Step-by-step explanation:

The exterior angle is equal to the sum of the 2 opposite interior angles, that is

2x - 2 = x + 45 ( subtract x from both sides )

x - 2 = 45 ( add 2 to both sides )

x = 47

Then

exterior angle = 2x - 2 = 2(47) - 2 = 94 - 2 = 92°
