Answer:
C
Step-by-step explanation:
A function cannot have multiple y values for one x value.
Option A lists the y values of -8 and 10 for the x value of -4. Therefore this is not a function.
Option B lists 0, 5, 10, AND 15 all for -1. This can't be a function either.
Option C does not have two of the same x values for different results. Although both 0 and 9 give you the answer of 1 for the y value, this is perfectly okay in a function. This is your answer.
Answer:
Since Cn+1^1+Cn+2^2 = Cn+1^3 is false, there is no solution.

7 and 5 are prime numbers
Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
The practical dominion is from t = 0, when the ball starts motion until the time when the ball hits the ground.
To find the time when the ball hits the ground solve the equation:
h(t) = 0
=> -16t^2 + 68t = 0
Factor: t(-16t + 68) = 0 => t = 0 and -16t + 68 = 0
=> 16t = 68
=> t = 68/16
=> t = 4.25
So, the practical domain is 0 ≤ t ≤ 4.25 s.
Which also may be represented by t ∈ [0, 4.25s]
