Find the coordinates of the circumcenter of triangle ABC with vertices A(-4,5) B(-2,5) and C(-2,-2)

9514 1404 393

  (-3, 1.5)

Step-by-step explanation:

The circumcenter of a right triangle is the midpoint of the hypotenuse. Here, that is ...

  D = (A +C)/2 = ((-4, 5) +(-2, -2))/2 = (-6, 3)/2

  D = (-3, 1.5) . . . . the circumcenter

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
