Question

Find the distance between the pair of points. Give an exact answer and an approximation.

(2,7) and (4,10)

Answer 1

Answer :

Start with the distance formula:

√[(x2-x1)2+(y2-y1)2]
> we know that >
x1=2 , x2=4
Y1=7 ,Y2=10

Plugging your x and y values in you get:

√[(4-2)2+(10-7)2]

√[(2)2+(3)2]

√[(4+(9)]

√[(13] is the answer.
Which is 3.60

Answer 2

Approx.3.6

Explanation:

To find distance you need to use this formula:

d=sqrt of (x2-x1)+(y2-y1)

sqrt of(4-2) sqr+(10-7)sqr

sqrt of 2^2+3^2

sqrt of(4+9)

sqrt of (13)

approx.3.6
