What is the present value of a cash flow of $900 if the rate of annual interest is 4.5 % ? Round to the nearest cent.
The present value is $

Present value of a cash flow = $861.24 (Approx)

Step-by-step explanation:

Given:

Cash flow (CF) = $900

Annual rate of interest (r) = 4.5% = 4.5 / 100 = 0.045

Number of year (n) = 1 year

Find:

Present value of a cash flow = ?

Computation:

Present value of a cash flow = $861.24 (Approx)

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
