Answer:

Beam stick out = 2.09 ft

Step-by-step explanation:

Given:

Length of wooden beam = 12 ft

Side of bed =  5.5 ft by 8 ft by 2 ft

Find:

Length of wooden beam needed.

Computation:

Length\ of \ diagonal = \sqrt{a^2+ b^+ c^} \\\\\\ Length\ of\ diagonal =  \sqrt{5.5^2+ 8^2+ 2^2}\\\\ Length\ of\ diagonal =  \sqrt{30.25+64+4}\\\\Length\ of\ diagonal =  \sqrt{98.25}\\\\Length\ of\ diagonal =  \sqrt{30.25+64+4}\\\\Length\ of\ diagonal = 9.91

Length of wooden beam needed = 9.91 ft

Beam stick out = 12 ft - 9.91 ft

Beam stick out = 2.09 ft

Step-by-step explanation:

<u>Q1</u>

  • y = (x + 3i)(x - 7)
  • y = x² + 3ix - 7x - 21
  • <u>y = x² + (3i - 7)x - 21</u>

<u>Q2</u>

  • y = (x - √5)(x - i)
  • y = x² - √5x - ix + √5i
  • <u>y = x² - (√5 + i)x + √5i</u>
