The area of a square is given by:
A = s²
A is the square's area
s is the length of one of the square's sides
Let us take the derivative of both sides of the equation with respect to time t in order to determine a formula for finding the rate of change of the square's area over time:
d[A]/dt = d[s²]/dt
The chain rule says to take the derivative of s² with respect to s then multiply the result by ds/dt
dA/dt = 2s(ds/dt)
A) Given values:
s = 14m
ds/dt = 3m/s
Plug in these values and solve for dA/dt:
dA/dt = 2(14)(3)
dA/dt = 84m²/s
B) Given values:
s = 25m
ds/dt = 3m/s
Plug in these values and solve for dA/dt:
dA/dt = 2(25)(3)
dA/dt = 150m²/s
Answer:
So, the correct answer is 'Melatonin'.

thank me later
Is head the answer? I mean common sense thinks that your head would have to be faced forward with the rest of his body already having a certain position pf where they are. All that's left is the head.
When the distance is decreasing, the frequency of the received wave form will be higher than the source wave form. the sound changes because, the sound waves and their frequency changes as they pass by you as they are moving in the same direction. HOPE THIS HELPED YOU :)
