Answer:

  • 8) 76°
  • 9) 88°

Step-by-step explanation:

  • <em>Sum of exterior angles of any polygon is 360°</em>
<h3>Exercise 8</h3>

<u>Sum of given angles:</u>

  • 2x + 60° + 64° + 36° + 48° = 360°
  • 2x + 208° = 360°
  • 2x = 360° - 208°
  • 2x = 152°
  • x = 76°
<h3>Exercise 9</h3>

<u>Sum of given angles:</u>

  • x + 90° + 109°+ 73° = 360°
  • x + 272° = 360°
  • x = 360° - 272°
  • x = 88°

Answer: A = 4400(1 + 0.0825 x 22)

Step-by-step explanation:

A = accumulated amount

P = original amount  unloaded- $4400

r = rate - 8.25% = 0.0825

t = years = 22

= 4400(1 + 0.0825 x 22)

What are the solutions of the equation x^4 + 6x^2 + 5 = 0? Use u substitution to solve.
Radda [10]

Answer:

second option

Step-by-step explanation:

Given

x^{4} + 6x² + 5 = 0

let u = x², then

u² + 6u + 5 = 0 ← in standard form

(u + 1)(u + 5) = 0 ← in factored form

Equate each factor to zero and solve for u

u + 1 = 0 ⇒ u = - 1

u + 5 = 0 ⇒ u = - 5

Change u back into terms of x, that is

x² = - 1 ( take the square root of both sides )

x = ± \sqrt{-1} = ± i ( noting that \sqrt{-1} = i ), and

x² = - 5 ( take the square root of both sides )

x = ± \sqrt{-5} = ± \sqrt{5(-1)} = ± \sqrt{5} × \sqrt{-1} = ± i\sqrt{5}

Solutions are x = ± i and x = ± i\sqrt{5}
