Hope this helps and is correct
W=width of the pasture, and
<span>320000/w=length (parallel to river) </span>
<span>F=twice width + length </span>
<span>=2w + 320000/w </span>
<span>Find derivative of F with respect to w and equate to zero to find w. </span>
<span>i.e. </span>
<span>Solve for w in </span>
<span>dF/dw=0
hope it helps</span>
A) 85%
To get the percentage you need to do 34/40 to get 0.85. That number is in decimal form and you need to convert it to a percentage. Multiply 0.85 by 100 to get 85 which is your percentage
B) 135%
Same concept as A. Keep in mind that since 54 is greater than 40 the answer should be over 100%
So the math would look like:
54/40 = 1.35
1.35 X 100 = 135%
You are correct! Good job! I started this using the washer method and found that it was much more tedious than using the shell method, which worked very well and very easily. Very good work!
