A football is kicked toward the goal. The height of the ball is modeled by the function h(x) = -16t^2 + 64t where t equals the time in seconds and h(x) represents the height of the ball at time t seconds. What is the axis of symmetry and what does it represent?A. x = 2; it takes 2 seconds to reach the maximum height and 2 seconds to fall back to the ground
B. x = 2; it takes 2 seconds to reach the maximum height and 4 seconds to fall back to the ground
C. x = 4; it takes 4 seconds to reach the maximum height and 4 seconds to fall back to the ground
D. x = 4; it takes 4 seconds to reach the maximum height and 8 seconds to fall back to the ground
Answers
Answer 1
Answer:
We will solve the equation:
t(-16 t + 64 )=0, t1=0,
-16t+64=0, 16 t = 64, t2=4
This is a square function ( graph : parabola ) with the zeroes: t1=0 and t2=4.
The axis of symmetry is x=2. It takes 2 seconds to reach the maximum height and 2 seconds to fall back to the ground (Answer: A).
t(-16 t + 64 )=0, t1=0,
-16t+64=0, 16 t = 64, t2=4
This is a square function ( graph : parabola ) with the zeroes: t1=0 and t2=4.
The axis of symmetry is x=2. It takes 2 seconds to reach the maximum height and 2 seconds to fall back to the ground (Answer: A).

Answer:
x = 3
Step-by-step explanation:
m<R = 180 - 110 = 70
m(arc)KQ = 2 × 70 = 140
m(arc)PQ = 140 - 50 = 90
30x = 90
x = 3

The answer is 3. First you solve 16-4 and you get 12. Then you solve 36/12 which equals 3.
You subtract ➡️. first 16-4= 12
Then divide ➡️. 36 divided by 12 is =3 so the answer is 3
Then divide ➡️. 36 divided by 12 is =3 so the answer is 3

1/3 / 2/7
The first thing you do is switch the 2 and the 7 around and change the sign to a times:
1/3 X 7/2
1 X 7 = 7
3 X 2 = 6
1/3 X 7/2 = 7/6
7/6 (which is an improper fraction) can we written as 1 1/6 (which is a mixed number).
