Consider the table that includes the input and output values of a function. Which best describes the constant difference for the function?

a constant second difference of –6
a constant second difference of 8
a constant third difference of –6
a constant third difference of 8

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
