Answer:
5
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, 0)
d = 
= 
= 
= 
= 5
H equals 30 because 3 times 6 is 18 so 5 times 6 is 30
Answer:
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.
0 = -(x-2)^2 + 16
(x-2)^2 = 16
x-2 = 16
x-2 = 4
x = 6
This means the ball will hit the ground 6 seconds after Amir threw it.

Answer:
Maybe 12…
Step-by-step explanation:
would it be 12? I really don’t know sorry.
If I get it wrong I can just have a question and post it and you can get some points.
4x^2-5x-21 is of the form ax^2+bx+c, a quadratic equation.
so b in this case is -5
