Answer:

Step-by-step explanation:

The formula is area of circle x height

To find area do radius x radius x 3.14 so 49 x 3.14 = 153.86

Since the answer already has pi just do 49 x 10 = 490

hodyreva [135]

Find attached the missing cash flow stream

Answer:

Present value = $1,685,334 (rounded to the nearest whole)

Explanation:

Since the cash flow stream is uneven, you must discount each stream individually and after you have discounted every stream you can add each preset value to find the net present value.

The formula for present value is:

$\text{Present Value} = \dfrac{\text{Future Value}}{(1+r)^n}\\\\\ Where:\\ \\ r = \text{Rate of return=interest rate}\\ \\ n = \text{Number of periods}$

1. Year 1:

Future value = $250,000
r = 4%
n = 1

$Present\text{ }value=\$250,000/(1+0.04)^1=\$240,384.62$

2. Year 2:

Future value = $20,000
r = 4%
n = 2

$Present\text{ }value=\$20,000/(1+0.04)^2=\$18,491.12$

3. Year 3:

Future value = $330,000
r = 4%
n = 3

$Present\text{ }value=\$330,000/(1+0.04)^3=\$293,368.80$

4. Year 4:

Future value = $450,000
r = 4%
n = 4

$Present\text{ }value=\$450,000/(1+0.04)^4=\$384,661.89$

5. Year 5:

Future value = $550,000
r = 4%
n = 5

$Present\text{ }value=\$550,000/(1+0.04)^5=\$452,059.91$

6. Year 6:

Future value = $375,000
r = 4%
n = 6

$Present\text{ }value=\$375,000/(1+0.04)^6=\$296,367.95$

Total present value = $240,384.62 + $18,491.12 + $293,368.80 + $384,661.89 + $452,059.91 + $296,367.95 + $ 296,367.95

Total present value = $1,685,334.29 = $ 1,685,334

Hey there, the answer is C.

After multiplying, you will get .37278. However, it's asking you to consider the significant figure of 3 so you'll have to round it to .373. C has that only option

Erin is squaring numbers.

rewona [7]

If you square a number that is less than 1.

For example, say your number was 1/2
the square of 1/2 is (1/2)^2 = (1/2)(1/2) = 1/4
