200 / 16 = 12.5
i think is the answer
<span>H(t) = −16t^2 + vt + s
</span>
<span>H(t) = −16t^2 + 100t + 140
H(t) = 0 = </span><span>−16t^2 + 100t + 140
16t^2 - 100t -140 = 0
t = [100 +/- √ (100^2 -4(16)(-140) ) ] /(2(16))
t = 7.43 and t = - 1.18.
El que tiene sentido para la pregunta es t = 7.43 s.
Option B) 7 s (approximately)

Answer:
The perimeter of the dog's play area is 30 ft
Step-by-step explanation:
Rectangle:
- The opposite sides are congruent.
- The opposite angles are congruent.
- The sum of all four angles of a rectangle is 360°.
- The sum of two adjacent angles of a rectangle is 180°.
- The diagonals bisect each other.
- The perimeter of a rectangle is = 2(Length+width)
- The area of a rectangle is = Length × width
Given that,
The length of the long side of the dog's play area was = 10 ft.
So, Length of dog's play area is = 10 ft.
The length of the short side of the dog's play area was = 5 ft.
So, width of dog's play area is = 5 ft.
It is a rectangular plot.
So, the perimeter of the dog's play area is =2(Length+width)
=2(10+5) ft
=2(15) ft
=30 ft
2x - 27=56
