h(t) = -16t² + 50t + 5
The maximum height is the y vertex of this parabola.
Vertex = (-b/2a, -Δ/4a)
The y vertex is -Δ/4a
So,
The maxium height is -Δ/4a
Δ = b² - 4.a.c
Δ = 50² - 4.(-16).5
Δ = 2500 + 320
Δ = 2820
H = -2820/4.(-16)
H = -2820/-64
H = 2820/64
H = 44.0625
So, the maxium height the ball will reach is 44.0625
Percents are parts of 100, so we divide 53 by 100 to find the decimal form of 53%.
53 / 100 = 0.53
Answer:
black
Step-by-step explanation:
We have been given that an antique car is a car that is 25 years old or older. We are asked to find the hours it will take a car to become an antique.
We know that 1 year equal to 365 days.
1 day is equal to 24 hours.
To find number of hours in 1 year we will multiply 365 by 24.
Now we will multiply hours in one year by 25 to find hours in 25 years.
Therefore, it will take 
hours for a car to become an antique.
Answer:
Marti
Step-by-step explanation:
Marti is farthest because it says that greg's car travels 13 feet but after two seconds he was at 30.7 away from the start line and marti was 2 feet in front but martyi goes faster because her car goes way more faster every second: (16.5 > 13) so: Greg is 30.7 + 13 x 10 = 160.7 | Marti: 2 + 16.5 x 10 = 167, So Marti wins the race and should be crowned the winner.
