Answer: A1
Explanation: The columns are arranged alphabetically and the rows are ordered numerically. The cell address states the column, a letter, followed by the row, then a number.
Answer:
A
Explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
Security A : 11 = 1( 1 + r)^15
11^(1/15) = 1( 1 + r)
1.173 = 1 + r
r = 1.173 - 1
r = 17.33%
Security A : 16 = 1( 1 + r)^15
16^(1/15) = 1( 1 + r)
1.20 = 1 + r
r = 1.2 - 1
r = 0.2
r = 20%
Security B earned a higher average annual rate of return as 20% is greater than 17.33%
Answer:
p = 59.11 dollars
Explanation:
Given
Price: p(x) = 8eˣ (0 ≤ x ≤ 2)
Revenue; R = x*p = 8xeˣ
p = ? when R be at maximum
We can apply
dR/dx = d(x*p)/dx = 0
⇒ d(8xeˣ)/dx = 8*(1*eˣ + x*eˣ) = 0
⇒ eˣ*(1 + x) = 0 ⇒ x = - 1
as x = - 1 ∉ [0, 2]
then, we have
p(0) = 8e⁰ = 8
R = 0*8 = 0
If x = 1
p(1) = 8e¹ ≈ 21.74
R = 1*21.74 = 21.74
If x = 2
p(2) = 8e² ≈ 59.11
R = 2*59.11 = 118.22
Implies that, R(x) is maximum at x = 2.
Thus, the price that maximize the revenue of the company is 59.11 dollars.
