Answer:

$1210

Step-by-step explanation:

The solution is one thousand two hundred ten dollars. p is one thousand dollars. r is six percent. t is three point five years. Multiplying, the interest earned is two hundred ten dollars.

To find the balance, add the principal, one thousand dollars, to the interest earned, two hundred ten dollars. This equals one thousand two hundred ten dollars.

Well, the formula for simple interest is 

I=prt

"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.

If you substitute the numbers, you get

I=1,000(0.06)(3.5)

When you multiply them together, you get 

I=210

So, the simple interest for 3.5 years is $210.

But, in order to get the total balance, you have to add the interest and the principal together.

B=1000+210 \\ B=1210

So, the balance after 3.5 years is $1,210.

GIVING BRAINIEST IF CORRECT!!<br><br> Factor x^4 - 16 completely
ioda

Answer:

(x^2 + 4)(x + 2)(x - 2)

Step-by-step explanation:

Hello!

We can use the difference of square method.

<h2>Difference Of Squares (DOS)</h2>

The formula for the DOS is (a + b)(a - b) = a^2 - b^2

It is a simple way to factor polynomials.

The criteria:

  • Has to begin and end with a perfect square
  • The operation has to be subtraction

<h3>Factor:</h3>
  • x^4 - 16

Begins with a perfect square (x² * x²) and ends with a perfect square (4 * 4)

  • (x^2 + 4)(x^2 - 4)

Warning! Watch out, there may be another DOS!

x^2 - 4 is another DOS

  • (x^2 + 4)(x + 2)(x - 2)

The x² + 4 is not a DOS because the operation is addition.

The final factored form is (x^2 + 4)(x + 2)(x - 2)
