Write an explicit rule for the sequence 12, 8, 4, 0? A. an = -4n + 12

B. an = 4n + 12

C. an= -4n + 16

D. an= 4n + 16

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

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
