Answer:
The ball will take 4.05 seconds to hit the ground.
Step-by-step explanation:
we have

This is a quadratic equation (vertical parabola) open down
The vertex is a maximum
we know that
The ball hit the ground when h=0
Solve the quadratic equation
For h=0

The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute in the formula


---> the time cannot be a negative number

therefore
The ball will take 4.05 seconds to hit the ground.
Answer:
y=x
Step-by-step explanation:
As you can see from this graph, all of the x and y coordinates are the same, so it would only make sense for x and y to be equal.
Let’s say
Length= L
Width= W
L=2w
L+L+w+w=48 = 3L=48
48/3=16
L=16
W=8
