4 + y = 19
y = 19 - 4
y = 15
Answer: f(x)=125g+50
Explanation: He is charging $125 for each gold piece so you would multiply “g” and 125.
You would add 50 as a one time fee so you add 50.
Answer:
(h o k)(3)= 3
(K o h)(-4b)= - 4b
Step-by-step explanation:
Composition of a function and its inverse function returns the input
(h o k)(3)= 3
(K o h)(-4b)= - 4b
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.
