Answer:
average velocity at the inlet = 3.66 m/s
Explanation:
given data
discharge Q = 25 ft³
/min = = 0.417 ft³
vacuum cleaner = 1 in by 5 in = ft
solution
we know discharge that is express as
Q = Area × Velocity .............1
put here value and we will get average velocity at the inlet
average velocity at the inlet =
average velocity at the inlet = 3.66 m/s
Answer:
Planning and performing an experiment to answer the question.
Explanation:
Answer:
3 s
Explanation:
velocity=initial velocity +a*t
34=10 + 8t
24=8t
t=3 s
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.
