Given
The demand equation is given
here Q is liters purchased per year, P is the price in dollars per unit and k is a parameter =0.75.
Explanation
a. To determine the quantity of petrol demanded by the average motorist if the price is 1 dollar per liter.
b. To determine the change in quantity demanded.
It is given that the price of petrol increases from $1.0to $2.0 per litre on a sustained basis.
Then the equation becomes
The change in quantity demanded is
Substitute the values.
Answer
a.The quantity of petrol demanded by the average motorist if the price is 1 dollar per liter is 2000 litres per year.
b. The change in quantity demanded is the fall in demand due to negative sign which is 0.4054.
Answer
c

Answer:
3π
Step-by-step explanation:
The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.
The radius is given ad 6. So the circumference is:
2*π*6=12π
Now, since the angle of the arc is 90°, this is 1/4 of the circle.
This means that the arc length of this section will be 1/4th of the total circumference which is:
12π/4=3π
Answer:
The answer is 3054.8
Step-by-step explanation:
V = 4/3 × 22/7 × 9 × 9 × 9
V = 4 × 22/7 × 3 × 81
V = 4 × 22 × 243/7
V = 21384/7
V = 3054.8
Thus, The answer is 3054.8
