A water balloon is launched from a slingshot with an initial velocity of 64 f/sec. The height with respect to time can be modeled by the function h(t)=64-16t^2 where t is time in seconds

1)(0.75,55)

2)(1.5,28)

3)(2,0)

(2.25,-17)

(3,-80)

(4,-192)

Step-by-step explanation:

1) substitute "t" values in table into the equation:

64-16(0.75)^2=

55

64-16(1.5)^2=

28

64-16(2)^2=

0

64-16(2.25)^2=

-17(ball already reached ground and went underground)

64-16(3)^2=

-80

64-16(4)^2=

-192

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.
