Answer:

House A

Step-by-step explanation

For house A:

divide 125,260 by to to find 10%.

10% = 12,526.The you divide this by two to get 5%.

5% = 6,263.Next add the original figure with the 5%. To makes things simpler insted of adding 5% percent twice(since were calculating for two years) just add the 10% to the original figure you get:

125,260 + 12,526= $137,786

For house B:

This is a little different than before. Find ten percent then 5 percent.

10%= 12,016

5%=6,008.Next to find 1% divide the 10% again!

1%-1,201.6,After add the five percent and 1% to find 6%.

6%=7,209.6. Multiply the 6% by 2 to find the price for 2 years.Next add the original number to the 12%.

12%=14,419.2

17,419.2+120,160= $134,579.2

In conclusion:

Compare the prices-

A=$137,786

B=$134,579.2

House A earns more money after two years.

Your welcome,this took me forevever:)))))

Which of the following series are convergent?
Westkost [7]

Answer:

All of them

Step-by-step explanation:

According to the ratio test, for a series ∑aₙ:

If lim(n→∞) |aₙ₊₁ / aₙ| < 1, then ∑aₙ converges.

If lim(n→∞) |aₙ₊₁ / aₙ| > 1, then ∑aₙ diverges.

(I) aₙ = 10 / n!

lim(n→∞) |(10 / (n+1)!) / (10 / n!)|

lim(n→∞) |(10 / (n+1)!) × (n! / 10)|

lim(n→∞) |n! / (n+1)!|

lim(n→∞) |1 / (n+1)|

0 < 1

This series converges.

(II) aₙ = n / 2ⁿ

lim(n→∞) |((n+1) / 2ⁿ⁺¹) / (n / 2ⁿ)|

lim(n→∞) |((n+1) / 2ⁿ⁺¹) × (2ⁿ / n)|

lim(n→∞) |(n+1) / (2n)|

1/2 < 1

This series converges.

(III) aₙ = 1 / (2n)!

lim(n→∞) |(1 / (2(n+1))!) / (1 / (2n)!)|

lim(n→∞) |(1 / (2n+2)!) × (2n)! / 1|

lim(n→∞) |(2n)! / (2n+2)!|

lim(n→∞) |1 / ((2n+2)(2n+1))|

0 < 1

This series converges.

On a number line, the distance from zero to -8 is 8 units. Which equation demonstrates this concept? A. 82 = 64 B. |-8| = 8 C. |
emmasim [6.3K]

Answer:

Option B

Step-by-step explanation:

The absolute value of a number is how far a number is from zero. We can use ' | | ' to represent the absolute volume of a number.  The distance, or absolute value, of -8 is 8.

We can represent this by writing:

|-8| = 8

Option B should be the correct answer.

perimetrul unui paralelogram este de 30 cm.una dintre laturi are lungimea de 6 metri . dterminati lungimile celolrarte laturi
zzz [600]

To solve this problem you must apply the proccedure shown below:

1. By definition, the opposite sides of a parallelogram are parallel and have equal length.

2. The figure attached shows that the opposite sides with equal length are:

a=c\\b=d

3. Keeping this on mind, you have that the side <em>c</em> and <em>a</em> are equal and measure six centimeters.

4. To find the length of the other sides, you must apply the following formula for calculate the perimeter of a parallelogram:

P=2(a+b)

4. If you solve for <em>b</em>, you will obtain the measure of <em>b </em>and<em> d:</em>

30cm=2(6cm+b)\\30cm=12cm+2b\\b=9cm

Therefore the answer is:

 The lengths of the sides are: 6 cm, 6 cm, 9 cm and 9 cm.
