Answer:
2 secs; 65 feet
Explanation:
The function guiding the water bottle is given as:
f(x) = -16t² + 64t + 1
The bottle will reach maximum height when velocity, df/dt (velocity is the first derivative of distance) = 0.
Therefore:
df/dt = 0 = -32t + 64
=> 32t = 64
t = 64/32 = 2 seconds
This is the time it will take to reach the maximum height.
To find this height, we insert t = 2 into the function f(x):
f = -16(2)² + 64(2) + 1
f = -(16 * 4) + 128 + 1
f = -64 + 128 + 1
f = 65 ft
Its maximum height is 65 ft.
<span>The earth gets most of its energy from the sun. The answer is letter B. This
is because most of the living organisms on earth need sunlight to perform
activities that would balance the ecosystem. Sunlight is the reason for the

The greatest risk factor, well that depends because their is quite a few risk factors. it depends where the person is having the stroke. so say someone was having a stroke in the library then you would have to move everything out of the way so they cant hurt themselves and call the ambulance straight away and tell them the signs the person is showing to tell you their having a stroke e.g. face dropping, slowed speech and cant hold their arm up in the air on their own.
