A. would have the highest pitch because the sound vibration are close together and it would also be the fastest. B is incorrect because the sound waves are very which would give it a deeper voice and it would be the slowest
Hope this helps
Answer:

Step-by-step explanation:
Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:

Next we factor what we can so we can further simplify the rest of the equation:

We can now cancel out (x+2)

Next we factor out even more:

We cancel out x-4 and reduce the 3 and 6 into simpler terms:

And we can now simplify it to:

Answer:r=3cm,diameter =6cm and C=18.84cm
Step-by-step explanation:
To find the radius,diameter and circumference according to the diagram drawn above
r=3cm
Diameter=2×3cm
d=6cm
To find the circumference
C=2πr
C=2×3.14×3cm
C=18.84cm
Answer:
The population that gives the maximum sustainable yield is 45000 swordfishes.
The maximum sustainable yield is 202500 swordfishes.
Step-by-step explanation:
Let be
, the maximum sustainable yield can be found by using first and second derivatives of the given function: (First and Second Derivative Tests)
First Derivative Test

Let equalize the resulting expression to zero and solve afterwards:


Second Derivative Test

This means that result on previous part leads to an absolute maximum.
The population that gives the maximum sustainable yield is 45000 swordfishes.
The maximum sustainable yield is:


The maximum sustainable yield is 202500 swordfishes.
