graph the circle and label the circle's center and intercept with their coordinate pairs x²+y²-4x+4y=0

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the answer is:

mean: 6

mad: 2.14

6 equilateral triangles

y-3=-3/2(x+4)

ur very much welcome
