Square rstu is inscribed in circle p. given the coordinates for the vertices of the square, find the equation of circle p.
r(o, 4), s(6,2), t(4, -4), and u(-2,-2)
(x - 2)2 + y2 = 68
(x + 2)2 + y2 = 20
(x - 2)2 + y2 = 20

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Marco has $38.43 dollars in his checking account. his checking account is linked to his amazon music account so he can buy music. the songs he purchases cost $1.29. part 1: write an expression to describe the amount of money in his checking account in relationship to the number of songs he purchases. part 2: describe what the variable represents in this situation.

What is the 9th term in the geometric sequence described by this explicit formula? an=-6. (2)(n-1) apex
