Answer:

f(5) = 2

Step-by-step explanation:

To evaluate f(5), that is when x = 5 in the interval x ≥ 5

then

f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so

f(5) = 2

88 units

Step-by-step explanation:

In\: \triangle OBR \:\&\: \triangle OWN

BR || WN (Given)

Therefore,

\angle OBR \cong \angle OWN (Alternate angles)

\angle BOR \cong \angle WON (Vertical angles)

\therefore \triangle OBR \sim \triangle OWN (AA postulate)

\therefore \frac{OR}{ON} =\frac{BR}{WN} (csst)

\therefore \frac{OR}{56} =\frac{24}{42}

\therefore \frac{OR}{56} =\frac{4}{7}

\therefore OR =\frac{4\times 56}{7}

\therefore OR ={4\times 8}

\therefore OR =32

RN = OR + ON

RN = 32 + 56

RN = 88 units
