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 + (y − 2)2 = 144

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual? (b) you like neither of them. (c) you like exactly one of them. (d) redo () if a song can be replayed before all 8 songs are played.

The party planning committee has to determine the number of tables needed for an upcoming event. if a square table can fit 8 people and a round table can fit 6 people, the equation 150 = 8x + 6y represents the number of each type of table needed for 150 people.
