Write an equation for this parabola

focus (3, 2), directrix y= 8

BASEBALL When a ball is thrown, the path it travels is a parabola. Suppose a baseball is thrown from ground level, reaches a maximum height of 15.2 meters, and hits the ground 61 meters from where it was thrown. Assuming this situation could be modeled on a coordinate plane with the focus of the parabola at the origin, find the equation of the parabolic path of the ball. Assume the focus is on ground level.

Write an equation for this circle given the endpoints of a diameter

(4, -2) and (-4, -6)

LAWN CARE A sprinkler waters a circular section of lawn. a. Write an equation to represent the boundary of the sprinkler area if the endpoints of a diameter are at (– 12, 16) and (12, –16).

EARTHQUAKES A stadium is located about 35 kilometers west and 40 kilometers north of a city. Suppose an earthquake occurs with its epicenter about 55 kilometers from the stadium. Assume that the origin of a coordinate plane is located at the center of the city. Write an equation for the set of points that could be the epicenter of the earthquake.

Write an equation for the circle

center at (8,-9), tangent to y-axis
