question 20

Short Answer

Find the distance between the pair of points. Give an exact answer, and where appropriate, an approximation to three
decimal places.
- $\left( - \frac { 5 } { 8 } , 1 \right) \text { and } \left( - \frac { 5 } { 8 } , \frac { 1 } { 2 } \right)$
A) $\frac { 9 } { 4 }$
B) $\frac { 1 } { 2 }$
C) $\frac { 5 } { 2 }$
D) $\frac { 3 } { 2 }$

• A) \(\frac { 9 } { 4 }\)
• B) \(\frac { 1 } { 2 }\)
• C) \(\frac { 5 } { 2 }\)
• D) \(\frac { 3 } { 2 }\)
