Mr. Jones wants to place a chimney on his roof. It is recommended that the chimney be set at a height of at least 30 feet. The h
Tom [10]

Absolute value of any number is always positive because it represent distance and distance will always positive.

To place chimney at  least 30 feet , the distance along the width of the roof  (x) will be  x = 17.5 feet or x = 2.5 feet.

Since, The height of the roof is described by the function f(x)=−4/3|x−10| + 40

Since, minimum height is 30 feet.

So , substitute f(x)=30 in above expression.

                 30=−4/3|x−10| + 40

                   4/3|x−10| = 10

                      |x−10|=30/4

                      |x−10| = 7.5

Taking positive case,

                           x−10 = 7.5

                           x = 17.5 feet

Taking negative case,

                          x−10 = - 7.5

                          x = 10 - 7.5

                          x = 2.5 feet

If ON = MN, find MN.
Furkat [3]
Use Pythagorean theorem.

[tex]|ON|^2+|MN|^2=|OM|^2\\\\x^2+x^2=8^2\\\\2x^2=64\ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2=32\to x=\sqrt{32}\\\\x=\sqrt{16\cdot2}\\\\x=\sqrt{16}\cdot\sqrt2\\\\\boxed{x=4\sqrt2}

Answer: |MN| = 4√2.
