The path of the ball can be modeled by a parabolic function. The ball reaches a maximum height of 20 meters when the ball is horizontally 65 meters from the tee. If the xy-plane is overlaid on the figure such that the tee corresponds to the origin and each unit in the plane represents 1 meter, then the height of the ball above ground can be modeled by the quadratic function p, where p(x) is the height of the ball, in meters, above level ground and x is the horizontal distance from the tee. Which of the following correctly defines the function p?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
