Answer:
Step-by-step explanation:
The equation used to represent the height of the ball, h in feet after t seconds is expressed as
h = -16t² + 48t + 8
The equation is a quadratic equation. The plot of this equation on a graph would form a parabola whose vertex would be equal to the maximum height travelled by the ball.
The vertex of the parabola is calculated as follows,
Vertex = -b/2a
From the equation,
a = -16
b = 48
Therefore,
Vertex = - 48/2 × - 16 = 48/32 = 1.5 seconds
So the ball will attain maximum height in 1.5 seconds.
To determine the maximum height, we would substitute t = 1.5 into the given equation. It becomes
h = -16(1.5)² + 48(1.5) + 8
h = - 36 + 72 + 8 = 44 feet
10x-22=29-7x
17x=51
divide by 17
x=3

1A (fraction): 1/6
1B (decimal): 0.16 (6 continues)
1C (percent): 16.66 (6 continues)
2.
5+15+7+8+10+15=60
10/60 time she got 5
1/6 chance she gets a 5 again
2A (fraction): 1/6
2B (decimal): 0.16 (6 continues)
2C (percent): 16.66 (6 continues)
3.
Yellow: 3/10 chance
Red: 1/5 chance
Blue: 2/5 chance
Pink: 0/20 chance
You're welcome in advance.
Answer:
x < 5/4
Step-by-step explanation:
divide by 16 on both sides
x < 20/16 = 5/4
Answer:
51
Step-by-step explanation:
63 x 4/5 = 50.4, you cant a have a .4 bike so it rounds to 51
