what is the 19th term of a geometric sequence where a1=8 and a9=360. Round the common ratio and 19th term to the nearest hundredth.

REALLY need help on this one please please.

Answers

Answer:

Step-by-step explanation:

[tex]a_{1} = 8\\a_{9} = 360 = a_{1} \cdot r^9 = 8 \cdot r^9\\r = \sqrt[9]{\frac{360}{9} }  \cong 1.53[/tex]

By the formula of a geometric series:

[tex]S_{n} = a \cdot \frac{1-r^n}{1-r} => S_{19} = 8 \cdot \frac{1-1.53^{19}}{1-1.53}  = 6091.54[/tex]

Answer:

r = 1.6

a19 = 37800

Step-by-step explanation:

First term [tex] a_1 = 8 [/tex] and [tex] a_9 = 360 [/tex] of a geometric sequence and we are to find the 19th term along with the common ratio for this sequence.

We know that the general term of a Geometric Sequence is given by:

[tex]a_n= a \cdot r^{n-1}[/tex]

where [tex]a_n[/tex] is the nth term, [tex]a[/tex] is the first term, [tex]n[/tex] is the number of terms and [tex]r[/tex] is the common ratio.

Substituting the given values in the above formula to get:

[tex]360 = (8)*(r)^(9-1)[/tex]

[tex]360 = 8*(r^8)[/tex]

[tex]r^8 = \frac{360}{8}[/tex]

[tex]r^8 = 45[/tex]

r = 1.6

Finding the 19th term:

[tex]a_n= a \cdot r^{n-1}[/tex]

[tex]a_{19}= 8 \cdot 1.6^{19-1}[/tex]

a19 = 37800

A diameter of a circle had endpoints of (-5, 6) and (-5,-2). What is the equation of this circle?

Answers

Answer: OPTION A

Step-by-step explanation:

Apply the formula for calculate the distance between two points to know the value of the diameter of the circle:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\D=\sqrt{(-5-(-5))^2+(-2-6)^2}\\D=8[/tex]

The equation of the circle is standard form is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where r is the radius and (h,k) is the point of the center of the circle.

As we know the diameter, we can find the radius:

[tex]r=\frac{8}{2}=4[/tex]

Substitute it into the equation:

[tex](x-h)^2+(y-k)^2=(4)^2[/tex]

[tex](x-h)^2+(y-k)^2=16[/tex]

Then, the answer is:

[tex](x+5)^2+(y-2)^2=16[/tex]

The length of a rectangle is 2 times its width . If the perimeter of the rectangle is 36 inches, find its length and width

Answers

Answer:

Step-by-step explanation

If breadth =x

Length =2x

Perimeter = 2x +x +2x+x

36=6x

X=6

Therefore breadth =6

Length =12

Final answer:

The question asks about finding the length and width of a rectangle given its perimeter. By setting up and solving an equation, we found that the rectangle's width is 6 inches, and its length is 12 inches.

Explanation:

Given that the length of a rectangle is 2 times its width, and the perimeter of the rectangle is 36 inches, we are asked to find the length and width of the rectangle. We can start by defining the width as 'w' and the length as '2w'. The formula for the perimeter of a rectangle is 2(length + width). We can substitute our definitions of length and width into this formula to get 2(2w + w) = 36. Simplifying this gives 3w = 18, so the width is 6 inches. Therefore, the length is 2 × 6 = 12 inches.

Answers

A. $27.23

B. $ 467.77

Complete Question goes thus

Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5½% of the selling price.

A.How much commission will the salesperson earn by selling a couch for $495?

B.How much money will the store get from the sale of the couch?

Answer:

a. The total commission is $27.28

b. The store will get $468.72 from the sale of the couch

Step-by-step explanation:

a.

Commission can be referred to as the reward given by the company on goods for the employee to sell products in order to make more sales and more money.

Commission is calculated as follows:

Total commission = Total Sales * Commission Percentage

Given

Total Sales = $495

Commission Percentage = 5½%

Substitute in, the above values

Total Commission = $496 * 5½%

Total Commission = $496 * 5.5%

Total Commission = $496 * 0.055

Total Commission = $27.28

Hence, the total commission is calculated as $27.28

b. The amount remitted to the store is calculated as

Amount = Total Sales - Total Commission

Where Total Sales = $496

Total Commission = $27.28

Amount = $496 - $27.28

Amount = $468.72

Hence, the store will get $468.72 from the sale of the couch

2x - y = 4

(3, 2)
(2, 3)
(-3, -2)
(-2, -3)

Answers

Answer:

Its the point (3, 2).

Step-by-step explanation:

x^2 + y^2 = 13

2x - y = 4

From  the second equation  y = 2x - 4 so substituting in first equation:

x^2 + (2x - 4)^2 = 13

x^2 + 4x^2 - 16x + 16 = 13

5x^2 - 16x + 3 = 0

(5x - 1 )(x - 3) = 0

x = 0.2, 3.

Substitute x = 3 in the second equation:

2(3) - y = 4

y = 6 - 4 = 2.

The population of the United States is 3 × 108 people, and the population of the world is 6.9 × 109 people. How many times larger is the world population? Write your answer in standard notation.

Answers

Final answer:

The world population is approximately 23 times larger than the population of the United States.

Explanation:

The question is asking how many times larger the world population is compared to the population of the United States. You can determine this through division. In this case,
6.9 × 109 (the world population) divided by 3 × 108 (the US population) equals approximately 23. This means that the world population is approximately 23 times larger than the population of the United States.

Learn more about Population Comparison here:

https://brainly.com/question/12287830

#SPJ3

The answer is expressed in standard notation as 23.

To calculate how many times larger the world population is compared to the United States, we divide the world population by the population of the United States. Given the world population as 6.9 × 10^9 people and the U.S. population as 3 × 10^8 people, we perform the following calculation:

6.9  × 10^9 ÷ 3 × 10^8 = 23 times larger.

When we divide these two numbers, we subtract the exponents (since the bases are the same) resulting in 10^1, which is just 10. Multiply the non-exponential part: 6.9 ÷ 3, which equals 2.3. Therefore, 2.3 × 10 tells us that the world population is 23 times larger than the population of the United States. To write this in standard notation, we simply say the world population is 23 times larger.
