Answer:
a
The effect of a change in the price of a new pair of headphones on the equilibrium price of replacement tips ( dp/dpN) is
b
The value of Q and p at equilibruim is
and 5
The consumer surplus is
The producer surplus is
Explanation:
From the question we are told that
The inverse market demand is
The inverse supply function is
a
The effect of change in the price is mathematically given as
Now differntiating the inverse market demand function with respect to
We get that
b
We are told that $30
Therefore the inverse market demand becomes
At equilibrium
So we have
Where is the quantity at equilibrium
Substituting the value of Q into the equation for the inverse market demand function
5
Looking at the equation for we see that
For Q = 0
And for Q = 250
Hence the consumer surplus is mathematically evaluated as
Substituting value
And
The producer surplus is mathematically evaluated as
Answer:
Explanation:
initial velocity, u = 8 m/s
vertical height, h = 1 m
θ = 40°
Let the horizontal distance is d and the time taken is t.
Use second equation of motion in vertical direction
h = ut + 1/2 at²
1 = 8 Sin 40 x t + 0.5 x 9.8 t²
1 = 5.14 t - 4.9t²
4.9t² - 5.14 t + 1 = 0
so, t = 0.26 s (smaller value)
So, the horizontal distance is
d = u cos 40 x t
d = 8 cos 40 x 0.26
d = 1.6 m
Answer:
The correct option is;
Technician A only
Explanation:
Leaks in the cooling system parts such as the radiator cap can be tested with a pressure operated hand pump by attaching the pump cap to the pump with an adaptor and apply pressure enough for there to be a release of pressure at the cap.
The pressure added to the system should be maintained for up to two minutes. If the pressure drops quicker, then there is likely to be leaks in the system
The freezing and boiling point of the coolant is measured with an antifreeze tester which carries the appropriate apparatus to measure the coolants freezing and boiling points.
Answer:
i) O m/s² as velocity is constant
ii) 20m/s
iii)Hint:Calculate the area of the graph,that is;below the line, for the first 15 seconds only
