The third equation is the answer
The time taken for the golf ball to reach the ground is 1 s.
<h3>
Motion of the golf ball</h3>
The path of motion of the golf ball can be described as parabolic because it is projectile.
When the golf ball reaches the ground, the final velocity will be zero.
Velocity of the golf ball is change in height with time.
v = dh/dt
h(t) = -16t² + 32t + 128
dh/dt = -32t + 32
0 = -32t + 32
32t = 32
t = 1 s
Thus, the time taken for the golf ball to reach the ground is 1 s.

Answer:
the distance is 9.1 inches (please give brainliest)
Step-by-step explanation:
we must use the pythagorean theorem:
5.7^2 + 7.1^2 = c^2
(c being the distance being the two corners)
c^2 = 82.9
c = sqrt(82.9) ≈ 9.1
Answer:
andioop
Step-by-step explanation:
Answer:
Given the equations:
....[1]
.....[2]
Taking square both sides in [1] we have;
....[3]
Substitute the equation [2] into [3] we have;
Using identity rule:
then;
Add both sides we have;
Subtract 1 from both sides we have;
⇒
By zero product property we have;
x = 0 and 5x-4 = 0
⇒x= 0 and
For x = 0,
y = 2(0)-1 = -1
Since, the value of x = 0 doesn't satisfy the equations.
Therefore, the values of x is 0.8
