After 6 years, what is the total amount of a compound interest investment of $35,000 at 4% interest, compounded quarterly?

sammy [17]

Answer:

Step-by-step explanation:

The interest will be compounded quarterly every year, it means in each year the interest will be calculated 4 times.

In 6 years in total $6 \times4$ = 24 times the interest will be calculated.

The yearly interest rate is 4%. Hence, the quaterly interest rate will be $\frac{4}{4}$ = 1%.

Hence, after calculating 24 times, the amount will be turned to $35000 \times (\frac{101}{100} )^{24}$ = 44440.7127≅ 44441.

Hence, the total compound interest is $(44441 - 35000) = $9441

DO ANYONE KNOW HOW TI FIND THE AREA OF A REGULAR POLYGON?? ill give brainlest and points

zloy xaker [14]

Answer:

see explanation

Step-by-step explanation:

The area (A) of a regular decagon ( 10 sided ) is calculated as

A = 0.5 × perimeter × apothem

Here side length = 3.25, hence perimeter = 10 × 3.25 = 32.5 m, thus

A = 0.5 × 32.5 × 5 = 81.25 m²

Expand and combine like terms.<br> (3c^4-5c^6)^2

lora16 [44]

Answer:

$9c^{8} -30c^{10} + 25c^{12}$

Step-by-step explanation:

We can use formula (a-b)² = a² -2ab + b².

In our example a = 3c^4 and b = 5c^6

$(3c^{4} - 5c^{6})^{2} = [3c^{4} ]^{2} - 2*3c^{4} *5c^{6} + [5c^{6}]^{2}=\\=9c^{8} -30c^{10} + 25c^{12}$
