Find the 10th term of the geometric sequence 8,-16,32

Answers

Answer:

4096

GP = {8 , 16 , 32 , 64 , 128 , 256 , 512 , 1024 , 2048 , 4096...} Therefore , the 10th term of the sequence is 4096.

I hope it help you

The required 10th term of the geometric sequence 8, -16, 32 is -4,096.

What is geometric progression?

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

To find the 10th term of the geometric sequence 8, -16, 32, we first need to determine the common ratio (r) between consecutive terms.

r = (second term) / (first term) = (-16) / 8 = -2

So the common ratio is -2.

The nth term of a geometric sequence is given by the formula:

[tex]a_n = a_1 * r^{(n-1)}[/tex]

where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, r is the common ratio, and n is the term number.

To find the 10th term, we plug in a1 = 8, r = -2, and n = 10:

[tex]a_{10} = 8 * (-2)^{(10-1)}a10 = 8 * (-2)^9a_{10} = 8 * (-512)a_{10} = -4,096[/tex]

Therefore, the 10th term of the geometric sequence 8, -16, 32 is -4,096.

Jin sells concert tickets at the theater box office. The ratio of student tickets to adult tickets sold is 4 : 5. Each student ticket costs $5, and each adult ticket costs $7. Jin sells 189 tickets altogether. Part A: How many student tickets does Jin sell? How many adult tickets? Explain your reasoning. Part B: How much more money does Jin receive from selling adult tickets than from selling student tickets? Explain your reasoning

Answers

Answer:

Part A: 84, 105

Part B: $315

Step-by-step explanation:

Part A:

4 student tickets + 5 adult ticekts = 9 tickets

The ratio of student tickets to adult tickets to total tickets is

4 : 5 : 9

He sold x times more tickets than the numbers on the ratio.

He sold 9x tickets.

9x = 189

x = 21

Student tickets:

4x = 4(21) = 84

He sold 84 student tickets.

Adult tickets:

5x = 5(21) = 105

He sold 105 adult tickets.

Part B:

Student tickets:

He sold 84 student tickets at $5 each.

The amount of money from the sale of student tickets is:

84 * $5 = $420

Adult tickets:

He sold 105 adult tickets at $7 each.

The amount of money from the sale of adult tickets is:

105 * $7 = $735

Difference:

$735 - $420 = $315

84 student tickets, 105 adult tickets were sold by Jin and $315 more money does Jin receive from selling adult tickets than from selling student tickets

What is Equation?

Two or more expressions with an Equal sign is called as Equation

The ratio of student tickets to adult tickets sold is 4 : 5

4 student tickets + 5 adult ticekts = 189

4x+5x=189

9x = 189

Divide both sides by 9

x = 21

The number of Student tickets:

4x = 4(21) = 84

Jin sold 84 student tickets.

Adult tickets:

5x = 5(21) = 105

Jin sold 105 adult tickets.

Part B:

He sold 84 student tickets at $5 each.

The amount of money from the sale of student tickets is:

84 * $5 = $420

Adult tickets:

He sold 105 adult tickets at $7 each.

The amount of money from the sale of adult tickets is:

105 * $7 = $735

Difference:

$735 - $420 = $315

Hence 84 student tickets, 105 adult tickets were sold by Jin and $315 more money does Jin receive from selling adult tickets than from selling student tickets

In the 1990's about 75% of high school graduates attended college. A survey of 2,000 high school graduates was taken in 2018 that showed 1,453 attended college. Do these responses provide strong evidence that the 75% figure is not accurate for current graduates? State the hypothesis and your conclusion using statistical evidence. What does your conclusion mean in context?

Answers

Answer:

These responses do show strong evidence that the 75% figure is accurate for current high school graduates going off to attend college

Step-by-step explanation:

1453/2000 = .7265 or 72.65%

If 1,453 students of a 2,000 student high school attend college after high school, than 72.65% of the students in the high school on average will attend college after they graduate. This percentage compared to the 1990's are a mere 2.35% behind the 75% mark. In this example that is the difference between 1,453 students and 1,500 students. Since these percentages are relatively similar, a conclusion could be made that the 75% mark is an accurate average representation of how many high school graduates will attend college in the future.

A solid sphere is cut into 4 equal wedges the volume of each wedge is v=1/3r3 solve the volume for r

Answers

Answer:

r = (3V/π)^1/3

Step-by-step explanation:

Given that :

Volume of a sphere = V = 4/3πr³

Dividing into 4

4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³

V = 1/3πr³

Cross multiply

3V = πr³

Divide both sides by π

3V/ π = πr³/ π

3V/ π = r³

Take the cube root of both sides

r = (3V/π)^1/3
