Implicit differentiation
chain rule is important here
I'll show the steps partially




now evaluate for (-2,2)
x=-2 and y=2



that's it, simplest form
Answer:
2.3
Step-by-step explanation:
Suppose that Paolo and Sharon are the only consumers of ice cream cones in a particular market. The following table shows their monthly demand schedules: Price Paolo’s Quantity Demanded Sharon’s Quantity Demanded (Dollars per cone) (Cones) (Cones) 1 8 16 2 5 12 3 3 8 4 1 6 5 0 4 On the following graph, plot Paolo’s demand for ice cream cones using the green points (triangle symbol). Next, plot Sharon’s demand for ice cream cones using the purple points (diamond symbol). Finally, plot the market demand for ice cream cones using the blue points (circle symbol). Note: Line segments will automatically connect the points. Remember to plot from left to right. Paolo’s Demand Sharon’s Demand Market Demand 0 4 8 12 16 20 24 6 5 4 3 2 1 0 PRICE (Dollars per cone) QUANTITY (Cones)
"Sum" tells us it's an addition problem:
One term is 12 and the other is 9/x
SO
The expression is:
12+9/x
So just find 2% of 8000 and multiply by number of years since
I=PRT
R=rate
T=time in yyears
P=principle
I=interest
8000=principle
rate=2%
time in years=2
2%=0.02
so
I=8000 times 0.02 times 2
I=320
answe ris $320
