Answer:

Interest at the end of the first year is $105.93

Step-by-step explanation:

$800 at 12.5% APR compounded monthly.

Interest at the end of the year

= $800 *( (1+0.125/12)^12 - 1 )

= $800 * 0.132416

= $105.93

Answer:

A. 6x + 4

B. 22 cm

Step-by-step explanation:

The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.

When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.

What is the domain of the function y = RootIndex 3 StartRoot x minus 1 EndRoot?
finlep [7]

By definition of cubic roots and power properties, we conclude that the domain of the cubic root function is the set of all real numbers.

<h3>What is the domain of the function?</h3>

The domain of the function is the set of all values of x such that the function exists.

In this problem we find a cubic root function, whose domain comprise the set of all real numbers based on the properties of power with negative bases, which shows that a power up to an odd exponent always brings out a negative result.

<h3>Remark</h3>

The statement is poorly formatted. Correct form is shown below:

<em>¿What is the domain of the function </em>y = \sqrt[3]{x - 1}<em>?</em>
