I'm guessing D. toothpick, but i might be wrong.
Answer:
The marginal revenue is positive when Roland sells 144 driers per week ( D
Explanation:
Elasticity of demand = -0.463
P = $127
116 hair dryers sold per week ( q )
demand function is differentiable
<u>prove the true statement below</u>
Revenue = price per unit * quantity
determine the Marginal revenue = dr / dq
∴ MR = P + q dp/dq
price elasticity of demand E(p) = - dq / dp * p/q
where : E ( p ) = - 0.463 , q = 116 , p = $127
q * dp/dq = P / 0.463
∴ MR = P * 1.463 / 0.463
= 127 * 3.16 = $401.32
since the Marginal revenue > 0 HENCE The marginal revenue will be positive when Roland sells 144 driers per week.
Answer:
A
Explanation:
Frequency is defined by repetitions or periods per second. If we take any segment from each graph, we would see that graph A has the most repetitions per second.
The period of A is the shortest since the frequency is equal to 1/T, the smaller the period, the higher the frequency.
Answer:
Explanation:
Given
Temperature of gas at First stage
Pressure of gas at First stage
Volume Occupies
If the Pressure and Temperature at second stage is
Using ideal gas Equation
where P=Pressure
V=volume
R=Universal Gas constant
T=Temperature
n=no of moles
as n and R is constant therefore
thus
