First you need the midpoint formula. (x1+x2 divided by 2)and (y1+y2 divided by 2) Which would look like this.. 13+-6=7 and 7 divided by 2 is 3.5.... 8+-6=2 And 2 divided by 2 is 1. so your answer is (3.5, 1)

Which expression represents the distance between point (0, a) and point (a, 0) on a coordinate grid?

Tema [17]

The distance between any 2 points (x1,y1) and (x2,y2) is
$D= \sqrt{(x2-x1)^2+(y2-y1)^2}$

given
(0,a) and (a,0)
$D= \sqrt{(a-0)^2+(0-a)^2}$
$D= \sqrt{(a)^2+(-a)^2}$
$D= \sqrt{a^2+a^2}$
$D= \sqrt{2a^2}$
$D= a\sqrt{2}$

the disance is a√2

I need a solution to this quantitative aptitude problem<br>

Answer:

Step-by-step explanation:

Not sure about this but it looks like we subtract 1 from the first number then add 3 times the difference in the example (N) to get each subsequent number so the Z part is in 1:

10-1 = 9 and second value is 9 + 3*(15-10) = 24 and third is 24 * 3*18 = 78 and so on.

So 1 is:

9 24 78 141

The others are worked out in the same way:

so 2 is

5 44 107 173
