Find the distance between (12, –3) and (0, 2). i think its 13.42 but that doesnt sound right.
:
Lets find out:
The distance equation:
d = sqrt%28%28x2-x1%29%5E2+%2B+%28y2-y1%29%5E2%29
:
Assign your values as follows
x1 = 12
y1 = -3
and
x2 = 0
y2 = 2
:
d = sqrt%28%280-12%29%5E2+%2B+%282-%28-3%29%29%5E2%29
d = sqrt%28%280-12%29%5E2+%2B+%282%2B3%29%5E2%29; minus a minus is a plus
d = sqrt%28%28-12%29%5E2+%2B+%285%29%5E2%29
d = sqrt%28144+%2B+25%29
d = sqrt%28169%29; find the square root of 169 on a calc
d = 13

Perhaps a small math error somewhere
