Answer:
Number of vines that should be planted are 150.
Step-by-step explanation:
The number of pounds of pounds of grapes produced per acre is represented by the expression 
Where n = additional vines planted
To maximize the production of grapes we will find the derivative of A(n) and equate it to zero.


For 
3 - 0.02n = 0
0.02n = 3
n = 
n = 150
To check whether the maximum value of the function is at n = 150, we will find the second derivative A(n).

Which shows A"(n) < 0
Therefore, A(n) has the maximum value at n = 150.
Therefore, number of vines that should be planted are 150.

Answer:
28
Step-by-step explanation:
operating loss is loss when value of operating loss is more than gross profit.
In the given problem
cost: 284
price : 299
profit = 299 - 284 = 15
but given that there is operating expense as well.
operating expenses = 43
as expense is greater than profit there is loss which is called operating loss.
operating loss = operating expense - profit = 43 - 15 = 28
Thus, operating loss is 28.
Step-by-step explanation:
180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn't change since it is a full rotation or a full circle. Also this is for a counterclockwise rotation. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b)
As measured by the MAD, the variability ratio is
(MAD of 6th grade heights)/(MAD of 7th grade heights) = 1.2/0.6 = 2.0
The 4th selection is appropriate:
2.0
