Answer: After 50 minutes the bell is at a depth of 2000 ft so we can find the average rate by
2000/50 =40 ft per minute.
We ignore the 400 ft in 12 minutes because that is included when we take out the average at 50 minutes and adding it in would be an error of doubly entry.
Explanation:
Answer: 17.5%
Explanation:
The equilibrium will occur where the money demanded equals to the money supplied i.e Ms = Md
From the question, the supply of currency by the Central Bank = 40
Money Supply (Ms) = m × B
where m = Money multiplier = 2.5
Note that the money multiplier can also be equal to 1/rr in situations wherebt the consumers do not hold any currency.
rr = reserve ratio, = 0.4
B = monetary base = 40
Note that the monetary base here is 40.
Since reserve ratio = 0.4, therefore
m = 1/0.4 = 2.5
Therefore, Ms = m × B
= 2.5 × 40
= 100
Thus Money supply Ms = 100.
Money demand(Md) = Y(0.3 - i),
Y = income = 800
i = interest rate
Since (Md) = Y(0.3 - i),
Md = 800(0.3 - i)
Equate the equation for the money demand and money supply together.
Ms = Md
100 = 800(0.3 - i)
100 = 240 - 800i
800i = 240 - 100
800i = 140
i = 140/800
i= 0.175
= 17.5%
Therefore, the interest rate is 17.5%
Answer:
D. Project A has a standard deviation of expected returns of 20%, while Project B's standard deviation is only 10%. A's returns are negatively correlated with both the firm's other assets and the returns on most stocks in the economy, while B's returns are positively correlated. Therefore, Project A is less risky to a firm and should be evaluated with a lower cost of capital.
Answer:
The nominal value at the end of 17 years = $7,455.34
The real value at the end of 17 years = $2,437.95
Explanation:
Value at the end of 17 years = present value x (1+ interest rate)^t
The nominal value at the end of 17 years = $1,475 x (1.1)^17 = $7,455.34
The real value at the end of 17 years = $1,475 x (1.03)^17 = $2,437.95
