Question

find the distance . P(-7/2 , 5) ; Q(9/2 , 4)​

Answer 1

Step-by-step explanation:

Use Distance Formulae

√{(-7/2)-(9/2)}²+{5-4)²

√{-16/2}²+(1)²

√(256+4)/4

√260/4

√65 = 8 ( Approx)

so the distance is 8 units approx

Hope it helps

If you don't know the distance formulae then you are a foolish trying to solve this question... first learn concept then try question

Answer 2

Answer:

Distance of PQ is,

$\frac{2 \sqrt{65} }{2}$

Step-by-step explanation:

we have formula of distance

$pq = \sqrt{( \frac{9}{2} - ( - \frac{7}{2} ))^{2} + ( 4 - 5 ) ^{2} }$

$= \sqrt{ (\frac{9 + 7}{2} )^{2} + ( { - 1})^{2} }$

$= \sqrt{ \frac{256}{4} + 1 }$

$= \sqrt{ \frac{260}{4} }$

$= \frac{2 \sqrt{65} }{2}$
