I will assume you mistyped this question. For y = -1/16x^2 + 4x + 3, the answers to this question are
a) 3 feet
b) 67 feet
c) 64.741 feet
For a) we note that at x = 0, that is the instant where the ball leaves the hand. y(0) = 0.
For b), we find the vertex of y = -1/16x^2 + 4x + 3
y = -1/16x^2 + 4x + 3
y = -1/16(x^2 - 64x) + 3
y = -1/16(x^2 - 64x + 1024 - 1024) + 3
y = -1/16((x-32)^2 - 1024) + 3
y = -1/16(x-32)^2 + 64 + 3
y = -1/16(x-32)^2 + 67
The vertex is at (32,67) so 67 is the maximum height.
For c), we find the x-intercepts with the quadratic formula on
y = -1/16x^2 + 4x + 3=0:
x = [ -b ± √b^2 - 4ac ] / (2a)<span>
x = [ -4 ± √4^2 - 4(-1/16)(3) ] / (2(-1/16))
x = -0.741, 64.741
Only the positive solution, so 64.741 feet </span>
Answer:
1) Populations are majorly increasing in areas where shifting cultivation is practiced, causing there to be less area available for use of shifting cultivation.
2) Around the world, overall, there is much less unoccupied land that is able to be used for shifting cultivation.

Answer:
1. What was the neutral stimulus before learning
occurred?
D) The dentist
: The experience occurred when the dentist started working on the patient. But the learning started as soon as Jim heard the drilling sound.
2. What is the conditioned response?
C) Jim's muscles tensing and the anxiety that follows
: His muscles are conditioned to the sound of the drill. And so now every time he heard the sound, his muscles tense up.
3. What is the conditioned stimulus?
D) The sound of the drill: The stimulus would be the sound of the drill. The muscles only tense up and Jim experiences anxiety only when he hears the sound of the drill.
