Question
Represent $\big(1+\sqrt{9.5}\big)$ on the number line.
✓
Answer
Draw a line segment OB = 9.5 units and extend it to C such that BC = 1 unit.
Find the midpoint D of OC.
With D as centre and DO as radius, draw a semicircle.
Now, draw $\text{BE}\perp\text{AC},$ intersecting the semicircle at E.
Then, $\text{BE}=\sqrt{9.5}\ \text{units}.$
With B as centre and BE as radius, draw an arc, meeting AC produced at F.
Then,$\text{BF}=\text{BE}=\sqrt{10.5}\ \text{units}.$
Extend BF to G such that FG = 1 unit.
Then, $\text{BG}=\big(1+\sqrt{9.5}\big)$
