The standard equation of a circle with center (h, k) and a vertical axis of symmetry is (x - h)² + ( y - k)² =r² A circle's center is (3,- 2) and the radius is 12. Which equation models the circle? A)(x - 3) ² + (y + 2) ² = 12

B)(x + 3) ² = (y + 2) ² = 12

C) (x - 3) ² = (y + 2) ² = 144

D)(x + 3)² – ( - 2) ² = 144

There were 816 people at a concert when a band started to play. after each song, only half the people stayed to hear the next song. how many people were left at the concert after x songs? write a function to represent this scenario.

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.
