Answer:
B. $300
Explanation:
The interest revenue is computed below:
= Principal × rate of interest × number of months ÷ (total number of months in a year)
= $20,000 × 6% × (3 months ÷ 12 months)
= $300
The 6 months is calculated from October 1 to December 31
Simply we use the simple interest formula by considering the principal amount, rate of interest and time period so that the correct revenue can be computed
Answer:
Ans. The value today of Social Security's promise is $7,726.98
Explanation:
Hi, well, first we need to bring to year 45 all 14 cash flows, and when they are at year 45, we have to bring it to present value, discounted at 9% rate, or 0.09.
First, let´s bring to year 45 all 14 future cash flows, the formula to use is the following.
That is because the first annuity is received exactly in year 45, it should look like this.
Now we need to bring this to present value to asses the value today of Social Security's promise. For that, we use the following formula.
That is:
Best of luck.

Answer:
The dimensions are 1 m × 1 m × 5 m
Explanation:
Let the dimension be x, y, z
Volume = xyz = 5 m³ ................(1)
According to question:
Cost function, C = 110(xy) + 30(xy) + 14(2xz+2yz)
or
C = 140xy + 28xz + 28yz ..........(2)
We need to maximise (2)
Given condition (1)
Using the concept of lagranges multipliers
...........(3)
...........(4)
...........(5)
From (3) and (4) and(5)
140xy + 28xz = 140xy + 28yz = 28xz + 28yz
thus,
140xy + 28xz = 140xy + 28yz
or
28xz = 28 yz
or
x = y ............(a)
140xy + 28yz = 28xz + 28yz
substituting x from (a)
140(y)y + 28yz = 28(y)z + 28yz
or
140y² = 28yz
or
5y = z
and,
volume = 5 m³
or
xyz = 5 m³
or
x(x)(5y) = 5 m³
or
x²(5x) = 5 m³
or
5x³ = 5 m³
or
x = 1 m
Hence,
y = x = 1 m
and,
z = 5y = 5(1) = 5 m
Therefore,
The dimensions are 1 m × 1 m × 5 m
