PLEASE HELP FAST ILL GIVE BRAINLIEST AJGSAJSJDH 2) Maria Louisa looks at a sequence of shapes and records the number of vertices in each of the shapes in the sequence. The first shape has 3
vertices, the second shape has 5 vertices, and the third shape has 7
vertices.
If Maria Louisa assumes that the number of vertices in the sequence of
shapes follows the same pattern, how many vertices would she expect the
twenty-first shape to have?
A.
39
B.
41
C.
43
D.
45

7 is the median   7.875 is the mean

step-by-step explanation:

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

i think it is c hope that

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
