√(- 9 ) / (( 4 - 7 i ) - ( 6 - 6 i )) = 3 i / ( 4 - 7 i - 6 + 6 i ) =
= 3 i / ( - 2 - i ) = - 3 i / ( 2 + i ) =

=
- 1 - 2 i
B is the answer because if u subtact both x and y
Answer: Our required probability is 39.69%.
Step-by-step explanation:
Since we have given that
Probability of a bowler getting a strike during a particular frame = 63%
Number of frames are performed = 2
We need to find the probability that the bowler would be most likely to get a strike in each of the two frames.
So, it becomes,

Hence, Our required probability is 39.69%.
This is simple, cycle through the answers until you get 30 inches squared. The answer is height equals 5. 2x3x5=30
For this case we have the following variables:
t: time in seconds.
f (t): height as a function of time.
By the time Grace reaches the pool, the height is equal to zero.
We have the following table:
Time (t) (in seconds) Height f(t) (in meters)
1 25
2 20
3 15
4 0
We observe that the height is equal to zero after 4 seconds.
Equivalently:
Answer:
the following represents the x-intercept of f(t):
Grace reaches the swimming pool after 4 seconds
