Find the future value of an annuity due of $400 each quarter for 4 1 2 years at 13%, compounded quarterly. (Round your answer to

Flura [38]

Answer:

$9891.23

Step-by-step explanation:

The formula for future value of annuity due is:

$FV=P[\frac{(1+r)^{n}-1}{r}]*(1+r)$

Where,

FV is the future value of the annuity (what we need to find)
P is the periodic payment (here it is $400)
r is the interest rate per period (here 13% yearly interest is actually $\frac{13}{4}=3.25$ percent per period(quarter))
n is the number of periods (here the annuity is for $4\frac{1}{2}$ years, which is $4\frac{1}{2}*4=18$ periods, since quarterly and there are 4 quarters in 1 year)

Substituting all those values in the equation we get:

$FV=400[\frac{(1+0.0325)^{18}-1}{0.0325}]*(1+0.0325)\\=400[23.9497]*(1.0325)\\=9891.23$

Hence, the future value of the annuity due is $9891.23

What is the length of the shorter base of the Little Trapezoid trail?

valentina_108 [34]

Answer:

The length of the shorter base of the little trapezoid trail is 1 mi.

Step-by-step explanation:

Let the shorter base of the large trapezoid is S and the larger base of the large trapezoid is L.

Similarly, assume that the shorter base of the small trapezoid is s and the larger base of the small trapezoid is l.

Since, the trapezoids are similar, so

$\frac{L}{l} = \frac{S}{s}$

Now, given that S = 2 mi, L = 8 mi and l = 4 mi and we have to find s.

So, $s = \frac{S \times l}{L} = \frac{4 \times 2}{8} = 1$ mi. (Answer)

Serggg [28]

Answer:

$396

Step-by-step explanation:

The total cost of the patio = area of the patio x cost per square yard

area of the patio = area of a rectangle = length x breadth = 11 x 9 = 99 yards^2

total cost of the patio = 99 x 4 = $396
