From the information below the games is over in 3 sets. For Gina to win the match there are 3 possibilities.
1) Gina wins the first 2 sets with probability
2)Gina wins the first set. Looses the next set. Wins the third set.
3)Gina looses the first set. Wins the next 2 sets.
The required probability that Gina wins is the sum of the above 3 probabilities . That is the probability that Gina wins the match is
2x^2+8x+26=0
According to the . quadratic formula...
(-8+-
)/2=4
64-(4)(2)(26)=-144
= 12i
-8+-12i/4= -2+-3o
Answer A is correct
Answer:
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
