13
Step-by-step explanation:
Answer:
a=35x−x^2
Step-by-step explanation:
Having
70 ft of fencing with a
width of x
feet and knowing the perimeter of a rectangle is
p=2w+2l
we can state the length of the garden as:
70=2x+2l
and solving for l
we know the length with be:
2l=70−2x or l=35−x
And then knowing the formula for the area of a rectangle is
a=w⋅l
we can write the equation as:
a=x⋅(35−x)a=35x−x^2
The ball will hit the ground when h(t)=0 so:
16t^2-96t=0
16t(t-6)=0, since t>0
t=6
So the ball with hit the ground after 6 seconds.
