Answers

The best way is to use the Ratio Test to see that the series = ∑∞ₙ₋₁ n/5ⁿ converges.

In mathematics, convergence definition is the property (some described by myriad series and functions) that it approaches its limit more and more distinctly as the arguments (variables) of the function increase or decrease, or as the number of terms in the series increases.

For example, the function y = 1/x converges to zero as x increases. Even in this case, the final value of x doesn't affect the value of y to actually be zero, and the marginal value of y is zero, since y can be made arbitrarily small by choosing a large enough "x". The line y = 0 (x-axis) is known as the asymptote of the function.

According to the Question:

Let aₙ= n/5ⁿ. If  lim(n→∞)

|an+1|/ |an| <1, the Ratio Test will imply that  

∑∞ₙ₋₁ aₙ = ∑∞ₙ₋₁ n/5ⁿ converges.

Now,

aₙ₊₁ = n + 1/ 5ⁿ⁺¹

    = n + 1 /5.5ⁿ.

Therefore,

since these terms are positive,

    |aₙ₊₁|/|aₙ| = n + 1 /5⋅5ⁿ

⇒ n +1/ 5ⁿ → 1/5 as n→∞

Hence,

∑∞ₙ aₙ = ∑∞ₙ₋₁ n/5ⁿ converges.

A teacher plans to use a 40-inch long roll of string to form a border around a rectangular space on her bulletin board reserved for student use. What is the maximum amount of space, in square inches, that she can reserve on her bulletin board using this roll of string?

Answers

The maximum amount of space that the teacher can reserve on her bulletin board using the 40-inch long roll of string is 400 square inches.

A rectangle is a two-dimensional shape with four sides and four right angles. It is characterized by having two equal sides that are parallel to each other and two equal sides that are perpendicular to the first two sides.

First, let's consider the perimeter of the rectangle. The perimeter is the total length of the four sides of the rectangle.

So, if we use the entire 40-inch long roll of string to form the border, it will equal the perimeter of the rectangle. We can represent the length and width of the rectangle using variables "l" and "w", respectively.

The perimeter of the rectangle can be calculated using the formula: P = 2l + 2w.

Now, we can set the perimeter equal to 40 inches and solve for l and w.

P = 40

2l + 2w = 40

l + w = 20

Next, we want to find the maximum area of the rectangle. The area of a rectangle can be calculated using the formula: A = l * w.

So, to find the maximum area, we need to maximize the product of l and w. This can be done by setting l and w equal to half of the perimeter, or 20 inches each.

l = w = 20

A = l * w

A = 20 * 20

A = 400 square inches

What is −203 − (−136)?



I need help! :((

Answers

Answer:

-67

Step-by-step explanation:

- 203 - (-136)

The 2 minuses cancel out each other, turning it into a plus sign.

-203 + 136 = -67

Basic addition

Step-by-step explanation:

Because there is a double negative in between 203 and 136 that would turn into a positive

So

-203+136

Now because 203 is negative you would take 203 and subtract 136 to get 67

Because 136 is less then 203 it would still be negative

So

The answer is -67

from 6 positive and 8 negative numbers, 4 numbers are chosen at random (without replacement) and multiplied together. what is the probability that the product is a positive number?

Answers

Let's say event A is the selection of four positive numbers, event B the selection of four negative numbers, and event C the selection of two positive and two negative numbers.

Since four numbers are chosen without replacement,  n(A) = 6 × 5 × 4 × 3 = 360  n(B) = 8 × 7 × 6 × 5 = 1680. In event C, four numbers are to be chosen without replacement such that two numbers are positive and two numbers are negative.

This can be done in following ways:  + + – – OR + – + – OR + – – + OR – + – + OR – – + + OR – + + –  ∴ n(C) = 6 × 5 × 8 × 7 + 6 × 8 × 5 × 7 + 6 × 8 × 7 × 5 + 8 × 6 × 7 × 5 + 6 × 5 × 8 × 7 + 8 × 6 × 5 × 7  = 6 × (8 × 7 × 6 × 5)  =10080  Here, total number of numbers = 14  ∴ n(S) = 14 × 13 × 12 × 11 = 24024

Since A, B, C are mutually exclusive events,

Required probability = P(A) + P(B) + P(C)

= n(A)/n(S) + n(B)/n(S)+ n(C)/n(S)

= 360+1680+10080/24024

Original ratio Amount (spoonfuls) Oil 8 88 Vinegar 1 11 Total dressing 3 33

Answers

Answer:

Step-by-step explanation:

Based on the information in the tape diagram and table, we can see that the ratio of oil to vinegar in Iara's salad dressing is 8 to 1. This means that for every 8 spoonfuls of oil, she uses 1 spoonful of vinegar.

To calculate the amount of oil and vinegar in the dressing, we can use the following formula:

amount = original ratio * total amount of dressing ÷ (original ratio + 1)

For the oil, the formula would be:

oil amount = 8 * 33 ÷ (8 + 1) = 8 * 33 ÷ 9 = 88 spoonfuls

And for the vinegar, the formula would be:

vinegar amount = 1 * 33 ÷ (8 + 1) = 1 * 33 ÷ 9 = 11 spoonfuls

So the final answer is:

Oil: 88 spoonfuls

Vinegar: 11 spoonfuls

if she drove back home using the same path she took out to the university and arrives 7.1 h after she first left home, what was her average speed for the entire trip, in kilometers per hour?

Answers

Her average speed for the entire trip, in kilometers per hour, is equal to 2d / (7.1 * 3600) * 3600 km/h

Let's assume that the total distance of the round trip is d kilometers and that she drove at a constant speed of v km/h for the entire trip. The time it takes for her to travel the entire distance at speed v is given by t = d/v.

Since she drove back home using the same path she took out to the university, her average speed for the entire trip must be equal to her speed on the way out and back. Therefore, the total time it took for her to complete the round trip is 2t = 2d/v.

Since the total time it took for her to complete the round trip is 7.1 hours, we can set up an equation:

2d/v = 7.1 hours

Converting hours to seconds and solving for v, we have:

v = 2d / (7.1 * 3600) km/s

Finally, converting to km/h, we get:

v = 2d / (7.1 * 3600) * 3600 km/h

Therefore, her average speed for the entire trip, in kilometers per hour, is equal to 2d / (7.1 * 3600) * 3600 km/h

 One of the properties of a mirror reflection is that the angle of incidence i.e. the angle at which light strikes the mirror = angle of reflection i.e. the angle at which the light reflects off the mirror

These angles are shown as α and β in the diagram

The two triangles we choose to solve this problem are
ΔABC and ΔCED

Given that ∠BCA is a complementary angle to angle of reflection and ∠ECD is complementary to the angle of incidence, it follows that

m∠BCA = m∠CED

m∠BAC of ΔABC = m∠ECD of ΔECD = 90°

Therefore the third angles of both triangles are also equal

b) By the AA (or AAA) or Angle-Angle Similarity theorem, the two triangles are similar

Heather's school is selling tickets to the annual talent show. One the first day of ticket sales the school sold 3 senior citizen tickets and 4 child tickets for

a total of $46. The school took in $48 on the second day by selling 4 senior citizen tickets and 2 child tickets. What is the price of each ticket type?

Answers

The price of a child ticket is $4 and the price of a senior citizen ticket is $10

Let's call the price of a senior citizen ticket "x" and the price of a child ticket "y".

On the first day, the school sold 3 senior citizen tickets and 4 child tickets for a total of $46, so we can write the equation:

3x + 4y =46

On the second day, the school took in $48 by selling 4 senior citizen tickets and 2 child tickets, so we can write another equation:

4x + 2y = 48

Now that we have two equations, we can use substitution or elimination to find the value of x and y.

For substitution, we can solve one equation for one variable and then substitute that expression into the other equation. For example, let's solve the first equation for x:

x = (46 - 4y)/3

Then, we can substitute this expression for x into the second equation:

4((46 - 4y)/3) + 2y = 48

Expanding the left side of the equation:

(184 - 16y)/3 + 2y = 48

Multiplying both sides by 3:

184 - 16y + 6y = 144

Combining like terms on the left side:

184 - 10y = 144

Subtracting 184 from both sides:

-10y = -40

Dividing both sides by -10:

y = 4

So the price of a child ticket is $4. To find the price of a senior citizen ticket, we can substitute this value back into the equation we solved for x:

x = (46 - 4y)/3 = (46 - 4 * 4)/3 = (46 - 16)/3 = 30/3 = $10

So the price of a senior citizen ticket is $10.

An equation that you can use is 16=
.

Answers

Answer:

16 = 3x

Step-by-step explanation:

We are here given a equilateral triangle in which each side length measure is " x " .

By perimeter we mean the sum of all the side lengths of the figure.

By question , we have each side length as x ,

So its perimeter would be ,

x + x + x = 3x

But it is given that the perimeter is 16in . So they must be equal .

Hence our required equation is ,

16 = 3x

and if we want to solve out for x , divide both the sides by 3 ,

x = 16/3

and we are done!

The bar graph shows the number of games a soccer team played each month. Use the data to find each listed value.

Median =
Lower quartile =
Upper quartile =
Interquartile range =

Answers

By using the data from the bar graph, each of the statistical value are as follows;

Median = 6.

Lower quartile = 4.

Upper quartile = 7.5.

Interquartile range = 3.5

How to calculate the median number of game?

From the information provided in the bar graph above, we can logically deduce the following data set:

Data set = {3, 5, 6, 7, 8}

Median = 6.

For Q₁ of the lower half of the data set, we have:

Lower quartile, Q₁ = {3, 5}

Lower quartile, Q₁ = (3 + 5)/2

Lower quartile, Q₁ = 8/4 = 4.

For Q₃ of the upper half of the data set, we have:

Upper quartile, Q₃ = {7, 8}

Upper quartile, Q₃ = (7 + 8)/2

Upper quartile, Q₃ = 15/2 = 7.5.

Mathematically, interquartile range (IQR) is the difference between lower quartile (Q₁) and upper quartile (Q₃):

IQR = Q₃ - Q₁

IQR = 7.5 - 4

IQR = 3.5

suppose sean makes 10 tables a month, each of which he can sell for $200. given that the average cost of making each table is $150, should sean make more or fewer tables each month?

Answers

It's impossible to say Sean should base his decision on the marginal cost and marginal benefit of creating another table. The marginal cost of making a table is not the same as the average cost of making a table. As a result, there is insufficient information to determine what Sean should do.

The opportunity cost of an activity is the value of what must be sacrificed in order to engage in the activity (plus the cost). A cost that cannot be recovered at the time a decision must be made.

The science of decision-making is often used as a crude definition of economics. This stems from the fact that economics is frequently concerned with making the best decision in the most efficient manner. One way to quantify this is to consider total costs and total benefits.
